VAV/Zone Controller Overview

The OE326-23I-OR VAV/Zone Controller is designed for pres-sure independent VAV Box and Zone Damper applications. It is supplied with an integral Airfl ow Sensor and is mounted in a plastic enclosure.

The OE326-23D-OR VAV/Zone Controller is designed for pres-sure dependent VAV Box and Zone Damper applications and is mounted in a plastic enclosure.

The OE326-23I-OR and OE326-23D-OR VAV/Zone Controllers utilize terminal block connections for wiring. The 24 VAC power is supplied from a transformer (by others) wired to the VAV/Zone Controller using standard stranded wire and 2 position terminal blocks. The communications wiring is connected between the other VAV/Zone Controllers, CommLink 5, MiniLink PD5, HVAC unit controller or other controllers on the local loop by using 2 conductor 18 gauge twisted pair with shield wire which is connected to the VAV/Zone Controllers via a standard 3 posi-tion terminal block.

Both VAV/Zone Controllers are designed for use with an OE282-01 Zone Damper Actuator. The VAV/Zone Controller connects to the actuator via the modular cable that is included with the actuator.

The VAV/Zone Controller can use a Standard Room Temperature Sensor wired to the provided 3 position terminal block or an E-BUS Digital Room Sensor connected via the integral E-BUS cable connector or to the provided 4 position terminal block. The VAV/Zone Controller also has a 2 position terminal block for wiring a Discharge Temperature Sensor, if desired.

A relay output on the VAV/Zone Controller provides for one stage of electric heat or an On/Off Hot Water Valve if the controlled terminal unit is not a fan terminal unit.

An optional Expansion Module is available for applications us-ing fan terminals and/or more than 1 stage of electric heat, SCR electric heat, or modulating HW heat. The Expansion Module connects to the VAV/Zone Controller by means of a prefabricated E-BUS cable.

OVERVIEW

Mounting and Installation

Mounting & Installation

If you purchased the Round Zone Damper or Rectangular Zone Damper Kits from WattMaster, the controller and actuator are factory mounted and wired in the damper control enclosure. If your VAV/Zone Controllers are pressure independent, an airfl ow probe and pressure sensor will also be factory mounted and wired.

Most terminal unit manufacturers will offer the option of fac-tory mounting the Orion controls in their terminal units for an additional charge. An installation worksheet and instructions are available for the Orion VAV/Zone Controller package which can be shipped with the VAV/Zone control(s) to the terminal unit manufacturer to simplify factory mounting and wiring of the controller.

VAV/Zone Controller Package

NOTE: The VAV/Zone Controller defaults to Direct Acting, which means that when looking at the damper shaft, the damper rotates clockwise to open. If the damper on the terminal unit is not installed for clockwise to open operation, the WattMaster Zone Controller can be confi gured for counterclockwise to open opera-tion via the operator interface or through the Prism software. It must be changed prior to system start-up for the designated units for the zone damper to func-tion properly. See your operator interface or Prism manual for further information on reconfi guring for reverse acting operation. Installation is the same as for clockwise-to-open units except all references to clockwise will now be counter-clockwise direction.

1. The terminal unit damper (by others) should be installed so the damper shaft turns in a clockwise direction to open the damper. This is the software default for the VAV/Zone Controller Pack-age. If this is not possible, the Controller can be re-confi gured for counter-clockwise-to-open operation using the Prism software. See the note above for details. All installation instructions are based on the clockwise-to-open default. Check the damper for proper rotation and mark the end of the damper shaft to indicate open and closed positions.

2. Loosen the (2) shaft mounting bracket nuts on the ends of the damper actuator’s shaft mounting U-bolt and slide damper actua-tor assembly over the terminal unit damper shaft. The actuator may have to be rotated from position shown depending on the terminal unit’s available mounting area and damper shaft loca-tion and whether this is a left or right hand installation. Hand tighten the U-bolt nuts until the damper shaft is loosely secured to the shaft.

Space Temperature SensorsThe Space Temperature Sensors should be mounted in the space served by the equipment the sensor is connected or hard wired to. All Space Sensors should be mounted approximately 5 feet above the fl oor and in an area that does not experience direct sunlight or drafts in order to get accurate readings. Cabling or wiring should be routed so the wire or cable is protected from being pinched or punctured by building fasteners or materials.

Discharge Temperature SensorsThese sensors should be mounted in the supply air duct of the equipment. The Discharge Temperature Sensor should be mount-ed at least 10 feet away from any Heating or Cooling source and be mounted 3 duct diameters from any elbow.

Cabling or wiring should be routed so the wire or cable is pro-tected from being pinched or punctured by building fasteners or materials.

NOTE: If this is a stand-alone damper, this sensor would be mounted upstream of the damper to act as a Supply Air Sensor.

3. After positioning the damper actuator over the damper shaft, secure the damper actuator to the controller enclosure base using the supplied L-bracket and 2 screws.

4 Turn the damper blade to its fully closed position. With the manual override clutch button depressed, rotate the actuator clamp to within approximately 1/16 inch to ⅛ inch distance be-tween the actuator stop and the clamp, depending on the damper seal design. Tighten the (2) shaft mounting bracket nuts on the ends of the damper actuator’s shaft mounting U-bolt with an 8 mm wrench to 3-5 ft-lb of torque. On dampers with edge seals, the actuator will compress the damper blade seal when reaching the end position. Adjust the end stops, if required. Attach the actuator cable between the actuator and controller.


INSTALLATION & WIRING

Important Wiring Considerations

General

Correct wiring of the VAV/Zone Controller is the most important factor in the overall success of the controller installation process. The VAV/Zone Controller wiring has been simplifi ed by the use of modular connectors and prefabricated modular cables.

Voltage and Environment Requirements

The VAV/Zone Controller and expansion modules must be connected to a 24 VAC power source of the proper size for the calculated VA load requirements. All transformer sizing should be based on the VA rating listed in Table 1.

Table 1: Voltage and Environment Requirements

WARNING: When using a single transformer to power more than one controller or expansion module, the correct polarity must always be maintained between the boards. Failure to observe correct polarity will result in damage to the VAV/Zone Controller, actuator, and expansion module.


Please carefully read and apply the following information when wiring the VAV/Zone Controller Package. See Figure 10, page 20 for VAV/Zone Controller Package wiring and connections. See Figure 9, page 17 for connecting and wiring multiple VAV/Zone Controller Packages in a system.

1. Size and wire the transformer to be used for powering the Non-Modular VAV/Zone Controller Package(s) per the instructions. Failure to size the transformer and/or wire the Non-Modular VAV/Zone Controller Package(s) correctly may cause the VAV/Zone Controller Package to operate erratically or not at all. See Figure 8, page 16 for wiring and transformer sizing information.

2. All wiring is to be in accordance with local and nationalelectrical codes and specifi cations.

3. All 24 VAC wiring must be connected so that all ground wires remain common. Failure to follow this procedure can result in damage to the controller and connected devices.

4. Minimum wire size for 24 VAC wiring should be18-gauge.

5. Minimum wire size for all sensors should be 24-gauge. Some sensors require 2-conductor wire and some require3-or 4-conductor wire.

6. Minimum wire size for 24 VAC thermostat wiring should be 22 gauge.

7. Be sure that all wiring connections are properly insertedand tightened into the terminal blocks. Do not allow wire strands to stick out and touch adjoining terminals which could potentially cause a short circuit.

8. Do not pry on the connectors when connecting ordisconnecting the modular cables. Be sure to push in on the connector release clip and then pull straight up.

9. When communication wiring is to be used to intercon-nect VAV/Zone Controllers together or to connect to othercommunication devices, all wiring must be plenum-rated, minimum 18-gauge, 2-conductor, twisted pair withshield. WattMaster can supply communication wire that meets this specifi cation and is color coded for the network or local loop. Please consult your WattMaster distributor for information. If desired, Belden #82760 or equivalent wire may also be used.

10. Before applying power to the VAV/Zone Controller, be sure to recheck all wiring connections and terminations thoroughly.



Wiring Checks

One of the most important checks to make before powering up the system for the fi rst time is to confi rm proper voltage and transformer sizing. Each VAV/Zone Controller Package requires 6 VA of power delivered to it at 24 VAC. See pages 20-21 of this manual for complete wiring and transformer sizing information for the VAV/Zone Controller.

Check all modular connectors to be sure they are completely pushed and locked into their mating connectors. Confi rm that all sensors required for your system are mounted in the appropriate location and that the modular cables are plugged into the correct connectors on the VAV/Zone Controller. Check the actuator cable and be sure it is plugged in and secured to the modular connec-tor on the actuator and the VAV/Zone Controller circuit board modular connector. If using a Standard Room Sensor or terminal connection for an E-BUS Digital Room Sensor, check to make sure the wiring is correct. See Figure 10, page 20 in this manual for wiring details. If attaching an E-BUS Sensor with an E-BUS cable, make sure the E-BUS connector is connected to one end of the E-BUS sensor cable and the other end is connected to the E-BUS sensor connector on the VAV/Zone Controller. Be sure any VAV/Zone Controller Expansion Modules connected to the VAV/Zone Controller are also correctly wired per the VAV/Zone Controller Expansion Module wiring instructions on pages 20 through 23 of this manual.

After all the above wiring checks are complete, apply power to the transformer(s) that is connected to the VAV/Zone Controller.

Powering Up

When the Controller and Modules are fi rst powered up, the POWER LED should light up and stay on continuously. If it does not light up, check to be sure that you have 24 VAC connected to the controller, that the wiring connections are tight, and that they are wired for the correct polarity. The 24 VAC power must be connected so that all ground wires remain common. If after mak-ing all these checks, the POWER LED does not light up, please contact WattMaster Controls Technical Support for assistance.

Power Wiring

One of the most important checks to make before powering up the system for the fi rst time is to confi rm proper voltage and transformer sizing for each controller. Each VAV/Zone Control-ler requires 6 VA of power delivered to it at 24 VAC. You may use separate transformers for each device (preferred) or power several devices from a common transformer. If several devices are to be powered from a single transformer, correct polarity must be followed.

WARNING: Observe Polarity! All boards must be wired with GND-to-GND and 24 VAC-to-24 VAC. Failure to observe polarity will result in damage to one or more of the boards.

Check all wiring leads at the terminal block for tightness. Be sure that wire strands do not stick out and touch adjacent terminals. Confi rm that all sensors required for your system are mounted in the appropriate location and wired into the correct terminals on the VAV/Zone Controller.

After all the above wiring checks are complete, apply power to the VAV/Zone Controller.

120 / 24VAC

Some installers like to use one large 24 VAC transformer to power several devices. This is allowable as long as polarity is maintained to each deviceon the transformer circuit.

Usingseparate transformers also allows redundancy in case of a transformer failure. Instead of having 8 controllers inoperative because of a malfunctioningtransformer you have only 1 controller off line. If the installer does decide to use a large transformer to supply power to several devices, the followingtransformer and wire sizing information is presented to help the installer correctly supply 24 VAC power to the devices.

Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.

Each GPC-XP Controller requires 8 VA @ 24VAC power. In the examples below we have a total of 8 GPC-XP Controllers.

8 GPC-XP Controllers @ 8 VA each................ 8 x 8 VA = 64 VA.

The above calculation determines that our transformer will need to be sized for a minimum of 64 VA if we are to use one transformer to power all thecontrollers.

Next we must determine the maximum length of run allowable for the wire gauge we wish to use in the installation. Each wire gauge below has avoltage drop per foot value we use to calculate total voltage drop.

18ga wire.................................0.00054 = voltage drop per 1’ length of wire16ga wire.................................0.00034 = voltage drop per 1’ length of wire14ga wire.................................0.00021 = voltage drop per 1’ length of wire

For our example we will use 18 gauge wire. WattMaster recommends 18 gauge as a minimum wire size for all power wiring.

Next use the voltage drop per foot value for 18 gauge wire from the list above and multiply by the total VA load of the 8 controllers to be installed.

0.00054 (Voltage drop per foot for 18 gauge wire) x 64VA controller load = Volts/Ft.

WattMaster controllers will operate efficiently with a voltage drop no greater than 2 Volts. Divide the total allowable voltage drop of 2 Volts by thenumber you arrived at above and you have the maximum number of feet you can run the 18 gauge wire with an 75 VA transformer with no more than a2 Volt drop at the farthest controller from the transformer..

2 (Volts total allowable voltage drop)= 57.80

0.0346 (Voltage drop per 1 ft. @ 64VA load)

Parallel circuiting of the wiring instead of wiring all 8 controllers in series allows for longer wire runs to be used with the same size wire (as shown inour examples below).

Warning: If polarity is not maintained, severe damage to the devices may result. WattMaster Controls recommendsusing a separate transformer for each device in order to eliminate the potential for damaging controllers due to incorrect polarity.

0.0346

feet

It is often necessary for the installer to calculate and weigh the cost and installation advantages and disadvantages of wire size,transformer size, multiple transformers, circuiting, etc., when laying out an installation. No matter what layout scheme is decided upon, it is mandatorythat the farthest controller on the circuit is supplied with a minimum of 22 Volts.

Use WattMaster 2Conductor Twisted PairWith Shield Cable OrBelden 82760 OrEquivalent To ConnectBetween Each VAV/ZoneController ActuatorPackage And From TheUnit Controller, MiniLinkPD Or CommLink To TheFirst VAV/Zone ControllerActuator Package AsRequired By YourApplication.

24VAC Transformer (By Others)See Zone Controller TransformerSizing Information For CalculatingVA Requirements.

WARNING: If Multiple Controllers Are Wired To ASingle Transformer As Shown, Polarity Must BeObserved On All 24 VAC Wiring Or Damage To TheControllers Will Result.

CAUTION: Size PowerWiring Per Wire SizingInformation In This Manual.Be Sure Wiring Is Sized ForMinimum Voltage Drop ForYour Length Of Wiring Run.

NOTE: A Single Transformer Supplying Each VAV/Zone ControllerIndividually Can Be Used Or A Transformer Supplying Several VAV/ZoneControllers Can Be Used. Each Controller Requires 6 VA Minimum Power.Do Not Exceed 16 Controllers Attached To One Transformer (96 VA). AlsoSee Warning Note Regarding Polarity.

Figure 9: VAV/Zone Controllers Communication & Power Wiring Diagram





VAV/Zone Controller Inputs

Analog Space Sensor or Digital Space SensorA Standard Room Temperature Sensor that hard wires to the Space Sensor wiring terminals on the VAV/Zone Controller is used when an analog sensor is desired. When an E-BUS Digital Room Temperature Sensor is desired, it can connect to the Digital Space Sensor wire terminals on the VAV/Zone Controller or it can be connected to the E-BUS connector on the VAV/Zone Control-ler using an E-BUS pre-fabricated cable of the desired length. Discharge Temperature SensorThis sensor can be used for monitoring the discharge air tempera-ture of the terminal unit, round damper or rectangular damper used with the VAV/Zone Controller. The sensor is typically used when the terminal unit has reheat installed so the true temperature of the air being supplied to the space can be monitored. It should be mounted in the discharge duct downstream of the terminal unit where the VAV/Zone Controller is installed.

NOTE: If this is a stand-alone damper, this sensor would be mounted upstream of the damper to act as a Supply Air Sensor.

Occupied SwitchThis input is used when you have a motion switch or window switch to determine room occupancy and allows for setback of the heating or cooling during occupied periods.

Window Open Detection ModeIf the “Window Open Detection” button is checked, and the “Oc-cupied Switch” contacts (located on the VAV/Zone Controller) are open, the VAV/Zone controller will control to the Unoccupied Cooling and Heating Setpoints and the Damper will completely close. When the contacts are shorted, the unit will control to the Occupied Cooling and Heating Setpoints. If the “Reverse Contact Polarity” button is checked, then the unit controls to the Unoc-cupied Cooling and Heating setpoints when the Occupied Switch contacts are shorted, and control to the Occupied Cooling and Heating Setpoints when the contacts are open.

Motion Sensor Occupancy DetectionThis operation only occurs in the scheduled Occupied Mode. If the Motion Sensor Occupancy Detection button is checked, then the Occupancy Detection Time and Occupancy Duration Timeout setpoints are used to determine the cooling and heating setpoints of the VAV/Zone controller. A motion sensor is con-nected to the Occupied Switch contacts (located on the VAV/Zone Controller) and when motion is detected (contacts shorted together) for the Occupancy Detection Time period, the control-ler will display “Occupied Mode” and control to the Occupied Cooling and Heating setpoints. If no motion is detected for a period longer than the Occupancy Duration Timeout setpoint, (the

contacts will open) the controller will display “Occupied Room Empty” and the controller will go to the Occupancy Cooling and Heating Setback temperatures, until motion is detected again. If the “Reverse Contact Polarity” button is checked, then the unit controls the opposite. When no motion is detected (contacts shorted) the controller will display “Occupied Room Empty” and unit will control to the Occupancy Cooling and Heating Setback temperatures, until motion is detected. When motion is detected (contacts open) for the Occupancy Detection Time period, the controller will display “Occupied Mode” and control to the Oc-cupied Cooling and Heating setpoints.

Airfl ow SensorIf the OE326-23I-OR Pressure Independent VAV/Zone Control-ler is being used, the terminal unit’s pressure pick-up tube must be connected with FRP tubing to the barb fi ttings on the side of the VAV/Zone Controller. No wiring connections are required as the pressure sensor is integral to the VAV/Zone Controller. This pressure sensor input is used for CFM (airfl ow) calculations.

VAV/Zone Controller Outputs

Auxiliary Reheat RelayThis relay has a dry contact on the VAV/Zone Controller and can be confi gured for Auxiliary Heat or Box Re-heat. Box Re-heat is used when you only need 1 stage of electric heat or On/Off Hot Water Valve. Auxiliary Heat is selected when you are using Baseboard or some other Heating Source. Use this relay if the controlled terminal unit is not a fan terminal unit. When you are using a fan terminal unit or have more than 1 stage of electric heat, SCR electric heat, or modulating HW heat, the OE325-03 VAV/Zone Controller Expansion Module must be used.

Confi gure the relay for Auxiliary Heat if the heat being controlled by the controller is baseboard type heat or any other type heat that does not require airfl ow through box. The relay will be energized whenever the Space Temperature drops 0.5° below the Auxiliary Heat Setpoint and the damper will remain in the position determined by the mode of operation.

If the relay is confi gured for Box Reheat, then the relay will be energized whenever the Space Temperature drops below the Oc-cupied Heating Setpoint and the damper will go to the Minimum Damper During Box Heating Mode Setpoint. The stages of box reheat will need to be set to 1.

VAV/Zone Controller Inputs and Outputs



VAV/Zone Controller Expansion Module OutputsAs previously stated, when you are using a fan terminal unit or have more than 1 stage of electric heat, have SCR electric heat, or have modulating HW heat, the OE325-03 VAV/Zone Controller Expansion Module is required.

Binary Input - Proof of FlowThis input is for an airfl ow Proving Switch. It is only an option with Stand-Alone damper applications using electric reheat.

Relay #1 - Fan EnableThis relay is used for energizing the Fan on Series or Parallel Fan Terminal units.

Relay #2 - Heating Stage 1If you have at least 1 stage of Heat, this relay is used to energize the 1st stage of terminal unit Heat. This Heating Stage can either be used with Electric Heat or On/Off Hot Water Valve control.

Relay #3 - Heating Stage 2If you have 2 stages of Electric Heat, this relay controls the 2nd

stage of Electric Heat.

Relay #4 - Heating Stage 3If you have 3 stages of Electric Heat, this relay controls the 3rd

stage of Electric Heat.

Analog OutputIf you are using SCR Electric Heat or a modulating Hot Water Valve or modulating Steam Valve for Heating, this output can supply a 0-10 VDC signal for proportional control of the Valve or SCR Electric Heater.

VAV/Zone Controller Expansion Module Inputs and Outputs

Other Connections

E-BUS ConnectorsThe EBC E-BUS modular connectors are used to connect the optional OE325-03 VAV/Zone Controller Expansion Module to the VAV/Zone Controller. The expansion module is only required when staged electric heat (more than 1 stage), SCR electric heat, modulating HW heat, and/or fan terminal control is required.

The E-BUS connector can also be used to connect an E-BUS Digital Room Temperature Sensor to the VAV/Zone Controller if desired. Actuator Modular ConnectorThis modular connector is used to connect a modular cable from the VAV/Zone Controller to a damper actuator.

Communications Terminal BlockThis three position terminal block is used for connecting the communications wiring between each VAV/Zone Controller and/or to the MiniLink, HVAC Unit Controller, or other installed controller on the local communications loop. Communications wiring should be 18 gauge minimum 2 conductor twisted pair with shield Belden #82760 or its equivalent.

24 VAC Power Terminal Block

This two position terminal block is used to wire the 24 Volt power to the VAV/Zone Controller Packages. If desired, a single transformer can be used to power multiple VAV/Zone Control-ler Packages together, or a separate transformer can be used for each controller.

WARNING: If multiple controllers are to be wired to the same transformer, polarity must be observed or damage to the controller will result.

Slaved Zone Damper Wiring

For large zones, it may be necessary to have more than one air damper controlled by a VAV/Zone Controller Package and its associated space sensor. The Orion system allows for connecting up to two additional Slaved Zone Dampers to the master VAV/Zone Controller Package. Slaving is not available for pressure independent damper applications.

NOTE: Each slaved actuator is considered a modular device rated at 6 VA each. This 6 VA load must be included in the transformer sizing. See the previous section regarding transformer sizing for complete information.

Two Slave Wiring Adapters consisting of a slave wiring interface card and modular cable are supplied with the OE523 Round Slaved Zone Damper, OE738 Slaved VAV/Zone Rectangular Damper Kit, and the OE282-03 Slaved VAV/Zone Damper Kit. These are required when attaching slave actuator(s) to the master zone damper. One slave wiring interface card should be mounted near the control enclosure of the master VAV/Zone Controller Package. It is mounted by fastening the plastic snap-track to suit-able sheet metal mounting surface with the sheet metal screws provided. The other card is mounted in the control enclosure of the slaved zone damper. Run 24 AWG minimum wire between the slave wiring interface cards. Connect modular cables to the slave wiring interface cards and to the zone actuators as shown. See Figure 15, below for complete wiring details.

Controller Addressing & Baud Rate Setting

Before applying power for the fi rst time, it is very important to correctly address the controller and run through a few simple checks.

If the VAV/Zone Controller is to operate as a Stand Alone con-troller (not connected to any other HVAC unit or VAV/Zone Controller(s)), the controller address switch should be set for address 1. When the VAV/Zone Controller is to be connected to other VAV/Zone Controllers on a communication loop, each VAV/Zone Controller’s address switch must be set with a unique address between 1 and 58.

START-UP & COMMISSIONING

Initialization and Operator Interfaces

Figure 17: Operator Interfaces

Initialization

On system power-up, the “STAT 1” & “STAT 2” LEDs are ex-tinguished for a few seconds, and then STAT1 fl ashes a set of 3 fl ashes fi ve times. After that, STAT2 fl ashes the number of the address switch setting, so if the address switch is set to 7, STAT2 will fl ash 7 times. If the address is higher than 9, both STAT 1 and 2 will fl ash with STAT1 fl ashing the 10s and STAT2 fl ashing the 1s. For example, if the address is 34, STAT1 will fl ash 3 times and STAT2 will fl ash 4 times. After the address is fl ashed, there is a short delay and then the controller will go into damper calibration and the ACTUATOR LEDs will come on. The CW LED will be on while the actuator is driving clockwise, and the CCW LED will light when the damper is driving counter-clockwise. When the calibration is completed, the normal diagnostic fl ashes of STAT2 will be begin. If everything is operating correctly, STAT2 LED will blink once every 10 seconds. If there is a problem with the controller, STAT2 LED will blink more than once. These diagnostic fl ashes are described in the Troubleshooting section of this manual..

Operator Interfaces

The next step is confi guring the controller for your specifi c re-quirements. In order to confi gure the VAV/Zone Controller, you must use an operator interface. Four different operator interfaces are available for programming and monitoring of the VAV/Zone Controller. See Figure 17. They are as follows:

• Modular Service Tool SD• Modular System Manager SD• Computer with Prism 2 Software & CommLink 5 Installed• System Manager TS-L (Touch Screen - Limited Access)

Any of these devices or a combination of them can be used to access the status, confi guration, and setpoints of any controller on your communications loop.

If using the Modular Service Tool SD or the Modular System Manager SD for programming, refer to your HVAC Unit Control-ler’s Operator Interface SD Technical Guide. If using a computer and the Prism 2 software for programming, refer to the Prism 2 Technical Guide. If using the System Manager TS-L for moni-toring, please see the System Manager TS-L Technical Guide.

No matter which operator interface you use, we recommend that you proceed with the programming and setup of the VAV/Zone Controller in the order that follows:

1. Confi gure the controller for your application. 2. Program the Controller setpoints. 3. Review Controller Status Screens to verify system

operation and correct Controller confi gurations.



Configuration & Setup



VAV/Zone Controller Confi guration & SetupConfi guration can be accomplished by using either the Modular Service Tool SD, Modular System Manager SD, or a computer with Prism 2 software installed. Several options are available to confi gure the VAV/Zone Controller for the appropriate equip-ment it is installed on. All of these options can be set from the Confi guration Menu or Confi guration Screens with the exception of “AHU Heating Call Setpoint” which is set from the Setpoints Menu or Setpoints Screens.

Box Control MethodSet this confi guration item for the type of box the VAV/Zone Controller is used on. All options below are available with and without reheat. The options are:

• Cooling Only Box (VAV)• Heating/Cooling Changeover Box (Zoning)• Series Fan Powered Box (VAV & Zoning)• Parallel Fan Powered Box (VAV & Zoning)

Damper Operating ModeThis option sets the direction of rotation the damper moves when driving towards its full open position. The options available are:

• Direct Acting ( Clockwise-to-Open Damper)• Reverse Acting ( Counterclockwise-to-Open Damper)

NOTE: The Default is Direct Acting, which means that when looking at the damper shaft, the damper rotates clockwise to open. When the operating mode is changed, the damper will re-calibrate.

Voting ZoneWhen the VAV/Zone Controller is being used on a Zoning sys-tem as opposed to a true VAV system, this option must be set to allow the MiniLink to determine if this controller should be included in the zoning system voting process. If this is set to Yes, this controller will be included in the voting process. If this is a zoning system and it is set to No, this controller will not vote in the zoning system voting process. If this is a true VAV system, the option should be set to No. A maximum of 16 voting zones can be confi gured. The options available are:

• Yes• No

Pressure Independent Boxes-Airfl ow @ 1” W.C.If this is a pressure independent box, this option allows you to calibrate the box CFM correctly using the box manufacturer’s “K” factor. Enter the correct “K” ( CFM) factor for the inlet diameter of the box you are confi guring. See the “K” factor table that fol-lows if you are using the Round VAV/Zone Dampers.

NOTES: K-Factor in the table is corrected to 70 °F @ 1000 ft. elevation. For other elevations add 2% for each additional 1000 ft. of elevation.

Add 1% for each additional 10 degrees of temperature increase.

Expansion Relays - Steps of ReheatIf the box has Reheat supplied by an Electric Coil, this option must be set for the number of Electric Heating stages on the box. If the box has Hot Water Heat with a 2 position Hot Water Valve, set the number of stages to 1. For Hot Water Heat with a proportional Hot Water Valve, this must be set for 0. Options available are:

• No Staging• 1 Stage of Reheat• 2 Stages of Reheat• 3 Stages of Reheat

Proportional Heating SignalIf the box has Hot Water Reheat using a proportional Hot Water Valve, set this option to match the voltage signal required by the Hot Water Valve you are using. Options available are:

• 0-10 VDC Voltage Signal• 2-10 VDC Voltage Signal

Allow Box Heat With AHU HeatIf the box you are using has Reheat or Auxiliary Heat, confi gur-ing this setting to 1=Yes will allow the box Heat to operate at the same time as the HVAC unit Heat. Options available are:

• No• Yes

Multiple Daily Setpoints/SchedulesBy clicking on the “Use Schedule Space Setpoints” box, in the Prism Setpoints/Confi guration screen, you can set up to 5 Tem-perature Setpoint periods in a 24 hour period. You can select a Cooling and Heating Setpoint for the period from Midnight to the fi rst event, then different setpoints from the fi rst event to second event, then the second event to third event, then the third event to fourth event, and fi nally from the fourth event to midnight. Each of the event times and temperatures are confi gurable.

Table 2: Airfl ow K-Factor ( CFM) Requirements


START-UP & COMMISSIONINGVAV/Zone Controller Configuration & Setup

Main Fan StatusIf the VAV/Zone Controller is installed on a non-fan powered box that has Reheat, set this option to Yes in order to enable box Reheat only when the HVAC unit fan is running. A full description of how this setting affects the various box types in the occupied and unoccupied modes is contained in the Occupied Mode Sequences and Unoccupied Mode Sequences that follow later in this manual. Options available are No - Heat can operate without fan or Yes - Heat cannot operate without fan.

Push-Button Override Group ID#During Unoccupied Mode, all VAV/Zone Controllers with a cor-responding Group ID# will resume Occupied operation whenever any of the VAV/Zone Controllers with the same Group ID # has its push-button depressed to initiate an override condition. This allows you to group zones in various areas of the building. For example, individual tenants with several offi ces could restore occupied mode for just their zones and not affect other zones in the building.

The default group ID number for all VAV/Zone Controllers is set at the factory as 1. If you don’t want a specifi c zone(s) to be part of that group, you must give each one a distinct group number between 2 and 16.

NOTE: WattMaster recommends that your groups consist of at least 3 zones to ensure minimum airfl ow across the HVAC unit coil.

Dump ZoneThe dump zone is a controller without an actuator that is used to control a duct heater or Auxiliary Heat. If this VAV/Zone Controller is to be used as a Dump Zone, set this confi guration to 1=Yes. Options available are Yes or No.

AHU Heating CallThis setting is located under the Setpoints Menu or Setpoints Screens and is used only for the Unoccupied mode. For Non-Fan Powered Terminal units, this temperature setpoint is used to al-low a heating device such as baseboard heaters to be energized in an attempt to satisfy the heating demand prior to initiating the HVAC unit’s Supply Air Heating Mode. For Fan Powered Terminal Units, this setpoint can be used to operate the Series or Parallel box to satisfy the heating demand by using plenum air and reheat prior to initiating the HVAC Supply Air Heating Mode.

During unoccupied mode, when the temperature in the space drops below the AHU Heat Call setpoint, the VAV/Zone Control-ler sends a signal to the Unit Controller to initiate the HVAC unit Supply Air Heating Mode. This setpoint temperature can be set higher or lower than the Space Heating Setpoint.

NOTE: This setpoint follows the Unoccupied Heating Setpoint Setback.

Auxiliary HeatThe Auxiliary Heat option allows for a separate setpoint that is different from the other heating setpoints. The Auxiliary Heat Relay energizes at 0.5ºF below the Auxiliary Heat Setpoint and de-energizes 0.5ºF above the Auxiliary Heat Setpoint. The Auxiliary Heat will continue to function regardless of the HVAC Mode the Unit Controller is in or at any airfl ow condition. This is typically used to control baseboard or other perimeter heat sources. See Table 3, page 31 for a complete layout of the vari-ous fan and heat relay staging points.

Expansion Relays – Steps of ReheatIf only 1 stage of box heat is required and this is not a Fan Termi-nal Unit, use the Auxiliary Heat relay on the VAV/Zone Controller and select “Used for BOX Re-heating” in the Confi guration. Also in “Stages of Box Re-Heat” confi gure for 1 stage.

If the box requires more than 1 stage of reheat, the OE325-03 VAV/Zone Controller Expansion Module must be used and 2 or 3 stages of heat must be selected. If a Fan Terminal Unit is used, use the OE325-03 VAV/Zone Controller Expansion Module for all stages of heat.

Box ReheatThe box heat will be energized whenever the Space Temperature drops below the Occupied Heating Setpoint and the damper will go to the Minimum Damper During Box Heating Mode setpoint.

Window Open DetectionWhen this feature is selected, if the contacts on terminals BIN and GND are open, the controller will control to the Unoccupied Cooling and Heating Setpoints, and when the contacts are closed, it will go control to the Occupied Cooling and Heating Setpoints. Normally closed operation can be selected by confi guring reverse contact polarity. See the VAV/Zone Controller Inputs and Outputs section for more details.

Motion Sensor Occupancy DetectionWhen this feature is selected, if the contacts on terminals BIN and GND are open, the controller will control to the Occupancy Cooling and Heating Setback Setpoints. When the contacts are closed, it will go back to the Occupied Cooling and Heating Set-points. Normally closed operation can be selected by confi guring reverse contact polarity. See the VAV/Zone Controller Inputs and Outputs section for more details.

Scheduling & Operation Modes


SEQUENCE OF OPERATIONS

HVAC Modes of OperationThere are 7 possible modes of operation for the HVAC Unit and the VAV/Zone Controller. These modes are determined by the Supply Air Temperature (SAT) and/or space demand conditions. They are:

• Supply Air Vent Mode (Based on HVAC Unit SAT) This mode occurs when the Supply Air Temperature is within 2°F of the Space Temperature and stays in this mode until the Supply Air Temperature is above or below the Space Temperature plus or minus the Supply Air HVAC Mode Deadband.

Space Vent Mode (Based on VAV/Zone Controller Space Temp) This mode occurs when the Space Temperature is below the Cooling Setpoint and 1.0°F above the Heating Setpoint.

Scheduling Occupied/ Unoccupied Mode The VAV/Zone Controller monitors the communications loop for its Occupied and Unoccupied mode of operation command. Either the Unit Controller or a GPC-XP Controller can transmit the Oc-cupied command to the VAV/Zone Controller. This requires the VAV/Zone Controller Packages to all be connected to the system communication loop through their RS-485 connector and to be properly addressed for the command to be received.

Push-button Override OperationDuring unoccupied hours, you can force the VAV/Zone Controller and Unit Controller back to occupied operation by pressing the override button on the Modular Room Sensor or Digital Room Sensor. The operation for the push-button override sequence is different depending on which sensor you are using.

Standard Room SensorPushing the override button for less than 3 seconds initiates the override which will continue for a confi gurable duration of time (0-8 hours). If during the override period the button is pressed a second time for less than 3 seconds, an additional confi gurable du-ration of time (0-8 hours) will be added to the remaining override duration that is left at the time of pushing the button. Depressing the button between 3 and 10 seconds will cancel the override.

Digital Room SensorPushing the override button momentarily initiates the override which will continue for a confi gurable duration of time (0-8 hours). If during the override period the button is pressed a second time, it will cancel

Damper PositionsThe actual values for the minimum damper positions that are described in the following paragraphs can be confi gured by changing the values in the setpoint screens for the VAV/Zone Controller. These minimums are expressed in damper open percentages for pressure dependent terminal units or in CFM for pressure independent terminal units.

Cooling MinimumWhen the HVAC unit is in the Supply Air Cooling Mode but the space does not require cooling, the VAV/Zone damper will move to the Cooling Minimum position.

Heating MinimumWhen the HVAC unit is in the Supply Air Heating Mode but the space does not require Heating, the VAV/Zone damper will move to the Heating Minimum position.

Vent MinimumThis is the position the VAV/Zone damper will move to when the HVAC unit is in the Supply Air Vent Mode.

Supply Air Cooling Mode (Based on HVAC Unit SAT) This mode occurs when the Supply Air Temperature falls to less than the Space Temperature minus the Supply Air HVAC Deadband. To cancel the Supply Air Cooling Mode, the Supply Air Temperature must rise to within 2°F of the Space Temperature.

Space Cooling Mode (Based on VAV/Zone Controller Space Temp) This mode occurs when the Space Temperature rises above the Space Cooling Setpoint.

Supply Air Heating Mode (Based on HVAC Unit SAT) This mode occurs when the Supply Air Temperature rises to a temperature that is greater than the Space Temperature plus the Supply Air HVAC Deadband. To cancel the Supply Air Heating Mode, the Supply Air Temperature must fall to within 2°F of the Space Temperature.

Space Heating Mode (Based on VAV/Zone Controller Space Temp) This mode occurs when the Space Temperature falls below the Space Heating Setpoint.

Off Mode - (Not displayed) During Unoccupied Mode, the mode is considered OFF if the Space Temperature does not generate a Heating Mode or Cooling Mode based on the Unoccupied Heating & Cooling Setpoints.


SEQUENCE OF OPERATIONSVAV/Zone Occupied Mode Sequences

When the HVAC unit is in the Supply Air Cooling Mode, the damper is normally held at the Minimum Cooling Position until the Space Temperature begins to rise above the Occupied Cool-ing Setpoint. As the Space Temperature rises to within 0.5ºF of the Occupied Cooling Setpoint, the Damper/Airfl ow calculation causes the air valve to open proportionally until the Maximum Setpoint is achieved at 1.5ºF above the setpoint. This is a 2ºF Proportional Window starting 0.5ºF below the Occupied Cooling Setpoint to 1.5ºF above the Occupied Cooling Setpoint.

The Damper Position/Airfl ow is never allowed to modulate out-side the user-adjustable Minimum and Maximum setpoints. The Maximum Damper Position/Airfl ow Setpoint applies to Heating and Cooling modes of operation only. All of the modes have their own individual minimum setting.

Series Flow Fan TerminalsIf the VAV/Zone Controller has been confi gured as a Series Fan Powered terminal unit, the series fan relay will activate and run the series box fan continuously anytime the HVAC unit fan is running.

In all cases, before the series box fan can be activated, the air damper is driven fully closed and held that way for 30 seconds to make sure the series box fan hasn’t inadvertently started to spin backwards. Once the series box fan starts, it waits an additional 10 seconds to allow the fan to spin up before it starts to open the damper and introduce airfl ow from the HVAC unit fan.

Parallel Flow Fan TerminalsDuring normal cooling or vent mode and adequate air supply, the parallel fan will be off. During the Occupied Cooling Mode, the fan will only activate if the damper/airfl ow is below a user-defi ned low limit setting. This causes it to be used as a supplemental air source. When the damper/airfl ow rises 15% above the low limit setpoint, the fan will be deactivated.

NOTE: A VAV/Zone Controller Expansion Module is required for each VAV/Zone Controller used when you are using a Fan Terminal even if you do not have any heat requirements. All Single Duct Terminal Units with multiple heat stages or modulating heat also require a VAV/Zone Controller Expansion Module.

Night MinimumThis is the position that the damper moves to during the Unoc-cupied mode. When using non-fan powered terminal units, the VAV/Zone damper will position itself in the Night Minimum position. In order for fan powered terminal units to position the damper to the Night Minimum position, the check for main fan status must be selected, and the HVAC unit fan must be operating.

Box Heating MinimumThis is the position that the damper moves to when Reheat is initiated. If the VAV/Zone Controller is used on a terminal unit that has reheat, the VAV/Zone damper will move to the Reheat position whenever a Space Heating demand occurs and the HVAC unit is in Supply Air Cooling or Vent Mode. When the HVAC unit is in Supply Air Heating Mode, the VAV/Zone damper will modulate as required to maintain the Space Heating Setpoint.

Occupied Mode Sequences

Space Vent ModeThis mode only applies to the Occupied Mode of operation. If the equipment is in the Unoccupied Mode, then a lack of heating or cooling demand would generate the Off Mode.

If the HVAC unit is in Supply Air Vent Mode, you can adjust the damper position on pressure dependent terminal units and the airfl ow on pressure independent terminal units to provide a fi xed amount of ventilation air into the space when there are no heating or cooling demands. During this time, the damper does not modulate on pressure dependent terminal units. On pressure independent terminal units, it only modulates to the extent re-quired to maintain the Vent Minimum Airfl ow setting.

If the VAV/Zone Controller detects that the HVAC unit is in Sup-ply Air Heating Mode, indicating that the air handler has activated its heat, the Heating Airfl ow Minimum will be substituted for the Vent Minimum.

If the VAV/Zone Controller detects that the HVAC unit is in Sup-ply Air Cooling Mode, indicating that the air handler has activated its cooling, the Cooling Airfl ow Minimum will be substituted for the Vent Minimum.

Space Cooling ModeOccupied Space Cooling mode is initiated by the temperature in the space rising to within 0.5ºF of the Occupied Cooling Setpoint.

If the HVAC unit is in the Supply Air Heating Mode and another VAV/Zone Controller has a cooling demand, the Damper Posi-tion/Airfl ow for the VAV/Zone Controller requiring cooling will position itself to provide the Heating Minimum Damper Position/Airfl ow Setpoint amount of air into the space. No modulation open will occur because the space does not want the warm air currently being supplied by the air handler.

VAV/Zone Occupied Mode Sequences



Space Heating ModeOccupied Space Heating mode is initiated by the temperature in the space falling to within 0.5ºF of the Occupied Heating Setpoint.

If the HVAC unit is in the Supply Air Cooling Mode and another VAV/Zone Controller has a heating demand, the damper/airfl ow for the VAV/Zone Controller requiring heating will position itself to provide the Cooling Minimum amount of air into the space. No modulation open will occur because the space does not want the cold air currently being supplied by the air handler.

When the HVAC unit is in the Occupied Supply Air Heating Mode, the damper will be held at the Heating Minimum posi-tion until the space temperature falls to within 0.5ºF of the Oc-cupied Heating Setpoint. As the Space Temperature falls below the Heating Setpoint, the damper/airfl ow calculation causes the air valve to open proportionally until the maximum setpoint is achieved at 1.5ºF below the setpoint. This is a 2ºF proportional window starting 0.5ºF above the Heating Setpoint to 1.5ºF below the Heating Setpoint.

Two different confi gurations are available for the Occupied Space Heating Mode. If the box is confi gured to allow reheat during Supply Air Heating Mode, the reheat relays can be activated even when the HVAC unit is in the Supply Air Heating Mode. If the box is confi gured not to allow reheat when the HVAC unit is in Supply Air Heating Mode, the box heat relays will be de-energized when the HVAC unit is in Supply Air Heating mode. In either confi guration, when the HVAC unit is in the Supply Air Heating Mode, the damper will modulate open proportionally to the space demand. The proportional window for the space temperature is to 1.5ºF below the Heating Setpoint. This allows the space to take advantage of the warm supply air in the duct.

The VAV/Zone Controller can activate auxiliary heating relays. Multiple heat stages or modulating heat can activate if the Ex-pansion Module has been connected and the correct number of additional heating stages (2 or 3) has been confi gured. During demands for Heat, the fi rst stage will activate whenever the space temperature drops below the Heating Setpoint. The second stage will activate if the Space Temperature falls 1.0ºF below the Heat-ing Setpoint. The third stage will activate if the Space Tempera-ture falls 2.0ºF below the Heating Setpoint. There is a two-minute delay between staging. This prevents stages from activating at the same time. Once a Heating Stage has been activated, it must remain on for at least one minute. Once it has been deactivated, it must remain off for at least two minutes. The third stage relay will deactivate when the Space Temperature rises to within 1.0ºF of the Heating Setpoint. The second stage relay will deactivate when the Space Temperature rises to the Heating Setpoint. The fi rst stage relay will deactivate when the Space Temperature rises above the Heating Setpoint by 1.0ºF. See Table 3 for a complete layout of the various Fan & Heat relay staging points.

Modulating ( Proportional) HeatThe VAV/Zone Controller Package with the Zone Controller Expansion Module provides an analog output for control of a Modulating Hot Water Valve or SCR Electric Heater. It provides a 0-10 VDC signal to control the heating device. When the space temperature drops to 0.5ºF above the Heating Setpoint the output starts at 0 VDC and ramps up to 10 VDC at 1.5 below the Heat-ing Setpoint.

Auxiliary HeatThe Auxiliary Heat option allows for a separate setpoint that is different from the other heating setpoints. The Auxiliary Heat Relay energizes at 0.5ºF below the Auxiliary Heat Setpoint and de-energizes 0.5ºF above the Auxiliary Heat Setpoint. The Auxiliary Heat will continue to function regardless of the HVAC Mode the Unit controller is in or at any airfl ow condition. This is typically used to control baseboard heat or an external duct heater. See Table 3 for a complete layout of the various fan and heat relay staging points.

VAV/Zone Unoccupied Mode Sequences



Series Flow Fan TerminalsIf the VAV/Zone Controller has been confi gured as a Series Fan Powered terminal unit, the series fan relay will activate and run the series box fan continuously anytime the HVAC unit fan is running.


Parallel Flow Fan TerminalsOn parallel fan powered terminal units, the fan will run when-ever Space Heating Mode is active. At all other times, the fan will only activate if the damper/airfl ow is below a user defi ned low limit setting. This causes it to be used as a supplemental air source. When the damper/airfl ow rises 15% above the low limit setpoint, the fan will be deactivated if there are no heating stages active, and no space demand exists.

The check for main fan status setting has no effect on the Parallel Fan box when in the occupied mode. The Parallel Fan will only be energized when in the Space Heating Mode.

Unoccupied Mode Sequences

Space Vent ModeThis mode only applies to the Occupied Mode of operation. If the equipment is in the Unoccupied Mode, then a lack of Heating or Cooling demand would generate “No Space Demand” on the Unit Controller display.

Space Cooling ModeDuring Unoccupied Mode, the HVAC unit is normally off. Unoc-cupied Space Cooling Mode is initiated by the temperature in the space rising to within 0.5ºF of the Unoccupied Cooling Setpoint.

If the HVAC unit is in the Unoccupied Supply Air Heating Mode because one or more of the VAV/Zone Controllers has a Heating demand and another VAV/Zone Controller has a Cooling demand, the damper/airfl ow for the VAV/Zone Controller requiring Cool-ing will position itself to provide the Heating Minimum Setpoint amount of air into the space. No modulation open will occur because the space does not want the warm air currently being supplied by the air handler.

When the HVAC unit is in the Unoccupied Supply Air Cooling Mode, the damper will be held at the Night Minimum Position until the Space Temperature begins to rise above the Cooling Setpoint. As the Space Temperature rises to within 0.5ºF of the Unoccupied Cooling Setpoint, the damper/airfl ow calculation causes the air valve to open proportionally until the maximum setpoint is achieved at 1.5ºF above the setpoint. This is a 2ºF proportional window starting 0.5ºF below the Cooling Setpoint to 1.5ºF above the Cooling Setpoint.

The damper/airfl ow is never allowed to modulate outside the user-adjusted minimum and the maximum setpoints. The Maximum Damper/Airfl ow Setpoint applies to Heating and Cooling Modes of operation only. All of the modes have their own individual minimum setting.

Series Flow Fan TerminalsIf the VAV/Zone Controller has been confi gured as a Series Fan Powered terminal unit and “Check for Main Status” has been selected, the series fan relay will activate and run the series box fan continuously anytime the HVAC unit fan is running. The damper will be held at the Night Minimum Position until the Space Temperature begins to rise above the Cooling Setpoint. If “Check for Main Status” has not been selected, the series fan relay will activate and run the series box fan when in the Space Cooling Mode. The damper will be in the fully closed position until the Space Temperature begins to rise above the Cooling Setpoint.


Parallel Flow Fan TerminalsIn the Unoccupied Cooling Mode, the parallel fan will be off whether “Check for Main Status” has been selected or not. If “Check for Main Status” has been selected, the damper will be held at the Night Minimum Position until the Space Temperature begins to rise above the Cooling Setpoint. If “Check for Main Status” has not been selected, the damper will be held in the fully closed position until the Space Temperature begins to rise above the Cooling Setpoint.


SEQUENCE OF OPERATIONSVAV/Zone Unoccupied Mode Sequences

Space Heating ModeDuring Unoccupied Mode, the HVAC unit is normally off. Un-occupied Space Heating Mode is initiated by the temperature in the space falling to within 0.5ºF of the Unoccupied Space Heating Setpoint.

If the HVAC unit is in the Unoccupied Supply Air Cooling Mode because one or more of the VAV/Zone Controllers has a cooling demand and another VAV/Zone Controller has a heating demand, the damper/airfl ow for the VAV/Zone Controller requiring heat-ing will position itself to provide the Night Minimum Position Setpoint amount of air into the space. No modulation open will occur because the space does not want the cold air currently being supplied by the air handler.

When the HVAC unit is in the Unoccupied Supply Air Heating Mode, the damper will be held at the Night Minimum Position until the Space Temperature begins to fall below the Unoccupied Heating Setpoint. As the Space Temperature falls to 0.5ºF below the Unoccupied Heating Setpoint, the damper/airfl ow calculation causes the air valve to open proportionally until the maximum setpoint is achieved at 1.5ºF below the setpoint. This is a 2ºF proportional window starting 0.5ºF above the Heating Setpoint to 1.5ºF below the Heating Setpoint.

As with the Occupied Mode of operation, two different confi gura-tions are available for the Unoccupied Space Heating Mode. If the box is confi gured to allow reheat during Supply Air Heating Mode, the reheat relays can be activated even when the HVAC unit is in the Supply Air Heating Mode. If the box is confi gured not to allow reheat when the HVAC unit is in Supply Air Heating Mode, the box heat relays will be de-energized when the HVAC unit is in Supply Air Heating Mode. In either confi guration, when the HVAC unit is in the Supply Air Heating Mode, the damper will modulate open proportionally to the space demand. The proportional window for the space temperature is 0.5ºF above to 1.5ºF below the Heating Setpoint. This allows the space to take advantage of the warm supply air in the duct.

If “Check for Main Status” is not selected and the VAV/Zone terminal unit has auxiliary heat (baseboard heat etc.) that does not require the HVAC unit fan to operate, reheat can be used without the HVAC unit fan operating. If “Check for Main Status” is selected, the reheat will only operate when the HVAC unit fan is operating.

The VAV/Zone Controller can activate auxiliary heating relays. Multiple heat stages or modulating heat can activate if the Ex-pansion Module has been connected and the correct number of additional heating stages (2 or 3) has been confi gured. During demands for Heat, the fi rst stage will activate whenever the Space Temperature drops below the Heating Setpoint. The second stage will activate if the Space Temperature falls 1.0ºF below the Heat-ing Setpoint. The third stage will activate if the Space Tempera-ture falls 2.0ºF below the Heating Setpoint. There is a two-minute

delay between staging. This prevents stages from activating at the same time. Once a heating stage has been activated, it must remain on for at least one minute. Once it has been deactivated, it must remain off for at least two minutes. The third stage relay will deactivate when the Space Temperature rises to within 1.0ºF of the Heating Setpoint. The second stage relay will deactivate when the Space Temperature rises to the Heating Setpoint. The fi rst stage relay will deactivate when the Space Temperature rises above the Heating Setpoint by 1.0ºF. See Table 3, page 31 for a complete layout of the various fan & heat relay staging points.

Modulating ( Proportional) HeatThe VAV/Zone Controller Package also provides an analog output for control of a Modulating Hot Water Valve or SCR Electric Heater. It provides a 0-10 VDC signal to control the heating device. When the Space Temperature drops to 0.5ºF above the Unoccupied Heating Setpoint, the output starts at 0 VDC and ramps up to 10 VDC at 1.5 below the Heating Setpoint.

Auxiliary HeatThe Auxiliary Heat option allows for a separate setpoint that is different from the other heating setpoints. The Auxiliary Heat Relay energizes at 0.5ºF below the Auxiliary Heat Setpoint and de-energizes 0.5ºF above the Auxiliary Heat Setpoint. The night offsets would apply to these values. The Auxiliary Heat will continue to function regardless of the HVAC Mode the Unit Controller is in, or at any airfl ow condition. This is typically used to control baseboard heat or an external duct heater.

Series Flow Fan TerminalsIf the VAV/Zone Controller has been confi gured as a Series Fan Powered terminal unit, the series fan will run continuously when the VAV/Zone Controller is in the Space Heating Mode, no matter whether check for main fan status has been selected or not. If the HVAC unit is in Supply Air Heating Mode, the damper will modulate to maintain the Space Heating Setpoint.

Any series fan terminal unit that has “Check for Main Status” selected will also operate its series box fan anytime the HVAC unit controller is broadcasting that the HVAC unit fan is operating, regardless of whether it is calling for heat or not. The damper will be held at the closed position until the main fan status broadcast is received. Once the broadcast is received, the damper will then move to its Reheat Minimum position. If “Check for Main Status” has not been selected, the series box fan will only activate and run when it is in Space Heating Mode. When in Space Heating Mode, the damper will move to its Reheat Minimum position. When in Supply Air Heating Mode, the damper will modulate to maintain the Unoccupied Heating Setpoint.



SEQUENCE OF OPERATIONS VAV/Zone Damper Control

Parallel Flow Fan TerminalsIf the VAV/Zone Controller has been confi gured as a Parallel Fan Powered terminal unit, the Parallel fan will run continuously when the VAV/Zone Controller is in the Space Heating Mode no matter whether “Check for Main Status” has been selected or not. At all other times, the fan will be off.

If “Check for Main Status” is selected, the damper will remain in the closed position until the HVAC unit controller is broadcast-ing that the HVAC unit fan is operating, regardless of whether it is calling for heat or not. The damper will be held at the closed position until the main fan status broadcast is received. Once the broadcast is received, the damper will then move to its Night Minimum position. If “Check for Main Status” has not been selected, the damper will stay in the closed position until Space Heating Mode is initiated. When in Space Heating Mode the damper will move to its Reheat Minimum position. When in Supply Air Heating Mode the damper will modulate to maintain the Unoccupied Heating Setpoint.

Damper ControlThe damper position is calculated by the demand from the space. This calculation can also include an optional Integral function. This prevents the damper/airfl ow from stagnating at a position somewhere above the setpoint because the Supply Air Temperature or Duct Pressure isn’t quite enough to satisfy the space at the currently calculated proportional position. The Integral causes the calculation to keep adding a small amount of the proportional error back into the damper/airfl ow position each time a new position is calculated. The amount the Integral adds back in is user-adjustable. This value is presented as a number between 0.0 and 10.0. That means that if the integral is less than 1.0, you are adding a percentage from 0 to 100% of the error back into the calculation. If you increase the Integral above 1.0, you are adding more than 100% back in.

With just proportional control, a 1ºF error would cause a 50% increase in damper/airfl ow if the Integral is not included. (1°F is half of the 2ºF Proportional Window).

If you had set the Integral to 1.0, the calculation would add 2% to the current damper/airfl ow calculation each time. The calcula-tion occurs once every 10 seconds, so it would take a little over 4 minutes to reach the programmed 100% maximum.

Example:

1. 50% Remaining / 2% Integral = 25 moves to get to a 100% Maximum2. 25 Moves times 10 seconds = 250 seconds or a little over 4 minutes to reach the 100% maximum damper/ airfl ow position.

Of course, different Space Temperature errors and different In-tegral values cause this calculation to operate slower or faster. It is up to the user to determine the optimum setting that provides the tightest temperature control without causing the damper to continue to hunt or modulate which causes premature wear of the actuator gears and motor.

On pressure dependent terminal units, the damper position is maintained to within ± 3% of the calculated position. No attempt is made to position the damper exactly on the calculated posi-tion. This reduces wear and tear on the actuator gears and motors and the amount of airfl ow involved is not affected by that small amount of damper error.

On pressure independent terminal units, the airfl ow is maintained to within roughly 3% of the terminal unit size constant but no tighter than 16 CFM on the smallest terminal units. The actual control window is based on the formula:

Window = Terminal unit size X Square Root (1 / 750)where Terminal unit size refers to the total rated CFM of the terminal unit

This sliding window allows the control to be much tighter on the smaller terminal units than can be achieved on the larger terminal units as far as CFM readings. On a large terminal unit, 25 CFM may not be noticeable, but on a small terminal unit, 25 CFM may be more than the minimum airfl ow setting for the space.

If the pressure sensor is disconnected or fails on a pressure in-dependent terminal unit, the controller automatically reverts to pressure dependent operation and generates an alarm to alert the user that a failure has occurred.

On either type of terminal unit, a space sensor failure will force the damper to position itself to the 50% of the maximum damper position setpoint, and it will not change until the sensor is repaired or replaced.


SEQUENCE OF OPERATIONSZoning

Zoning

The Orion Control System can be confi gured to operate as a true zoning system with the addition of a MiniLink PD 5. The Mini-Link PD 5 acts as a loop manager receiving information from the VAV/Zone Controller Packages, interpreting this information, and then sending a heat, cool, or vent signal to the Unit Control-ler. Only 16 zones can be confi gured as voting zones per loop. Additional zones will be non-voting.

Zone PollingThe MiniLink PD 5 must be confi gured for zoning operation using the Modular Service Tool SD, System Manager SD, or Prism 2 computer software. During the setup and confi guring, the user is required to enter the last Zone address on the loop. Once confi gured, the MiniLink PD 5 begins polling each VAV/Zone Controller for its temperature and setpoint information. A zone poll cycles through all confi gured zones in one pass without interruption.

The following is a list of status information required by the MiniLink PD 5 to correctly perform its HVAC mode calculations.

Zone Temperature Current Cooling Setpoint Current Heating Setpoint Current Zone Operating Mode Status & Alarm Conditions

A zone is considered Missing if it fails to respond to 5 consecu-tive polling requests. A Missing Zone alarm can be generated in less than 2 minutes. This alarm can generate an alarm callout to maintenance or a supervisor if the system has been properly setup. See the “Alarm Detection And Reporting” section for more information.

Zone VotingIf a zone has been confi gured for the Voting mode, the Mini-Link will perform the following tests based on the data received during the zone polling operation. These tests ensure that only properly operating zones can have an effect on the HVAC Mode calculation.

The zone has not been reported as Missing

The zone is not currently undergoing Damper Calibration

The zone damper does not have an alarm condition

The zone temperature readings are between 40°F and 105ºF

The Zone Cooling Setpoint is between 55°F and 105ºF

The Zone Heating Setpoint is between 48°F and 99°F

The zone has not been declared Maverick by the MiniLink

The zone has been confi gured as a Voting zone

If all the above tests are passed, the zone temperature and set-points are then included in the HVAC mode decision; otherwise, this zone is ignored.

Testing for Maverick ZonesDuring the HVAC mode decision process, a zone cannot be in-cluded in the Voting if it has been declared as Maverick. A zone is determined to be a Maverick if it stays 4ºF below the Space Heating Setpoint for 1 hour or 4ºF above the Space Cooling Set-point for 1 hour. During this 1 hour time period, the zone is still included in the voting, but it generates a Priority call for Heating or Cooling to the MiniLink. During this 1 hour time period, if the Space Temperature moves to within 2ºF of its Space Heating or Space Cooling Setpoint, the Priority and Maverick are both canceled. If the zone stays in Priority for greater than 1 hour, it then becomes a Maverick zone. At that point, its Priority is canceled and the zone is ignored in the voting process until the Space Temperature changes to within 2ºF of its Space Heating or Space Cooling Setpoint. If at least 75% of the zones go Maverick simultaneously, the MiniLink assumes an abnormal condition has occurred in the building and resets all the zones back to normal. It then restarts the 1 hour Maverick test over again for all zones. Maverick testing can be disabled if your system is connected to a computer with Prism 2, the Modular System Manager SD, or the Modular Service Tool SD.


SEQUENCE OF OPERATIONSAlarms & Tenant Override Logs

Alarm Detection and ReportingThe VAV/Zone Controller continuously performs self diagnostics during normal operations to determine if any operating failures have occurred. These failures can be reported to the user in sev-eral ways, depending on the type of system and options installed by the user. If a System Manager TS-L is connected, the alarms will be reported on the Status Screens. If the Prism 2 computer software is installed, the alarms will be reported on the main screen of the program and be logged to disk. If the remote com-munications option is installed, all alarms can initiate an e-mail to alert someone to the alarm condition. See the Prism 2 Technical Guide for further information on this topic.

VAV/Zone Controller Alarms

Space Sensor Failure Alarm If the controller detects an open or short on the Space Sensor input, this alarm will be generated.

CFM Sensor Failure AlarmIf the Airfl ow Constant (K Factor) is set to any value other than zero, and the controller does not detect the Airfl ow Sensor, this alarm will be generated.

Damper Opening AlarmAfter initial calibration, if the damper is called to be fully open and cannot reach that position within approximately 2 minutes, this alarm will be generated.

Damper Closing AlarmAfter initial calibration, if the damper is called to be fully closed and cannot reach that position within approximately 2 minutes, this alarm will be generated.

High Space Temp AlarmIf the zone temperature is above the Cooling Setpoint by the High Zone Alarm Offset (user adjusted) for the Zone Alarm Delay Period (user adjusted), this alarm will be generated.

Low Space Temp AlarmIf the zone temperature is below the Heating Setpoint by the Low Zone Alarm Offset (user adjusted) for the Zone Alarm Delay Period (user adjusted), this alarm will be generated.

Damper Feedback Failure AlarmIf the controller fails to detect the actuator feedback signal, this alarm will be generated.

Tenant Override LogsIf you require tenant billing for push-button override usage, a MiniLink PD 5 must be installed on each local loop. The Mini-Link PD 5 has the ability to track the amount of override time gen-erated by each space sensor equipped with push-button override.

Storing and retrieving these logs requires a dedicated computer running the Prism 2 front-end software program. No other method exists for retrieving these logs. This means that all of your units must be connected together on the communications loop and the loop must be terminated at a CommLink device connected to the on-site computer.

WARNING: The computer must be on 24 hours a day 7 days a week running the Prism 2 software in order for tenant logging to be tracked.

The tenant logs are kept on the dedicated jobsite computer’s hard drive. The only limitation to the number of logs stored is the capacity of the hard drive on the computer to which it is being logged.

NOTE: For proper time and date stamping of the tenant log, you must confi gure the air handler to broadcast the time so that the VAV/Zone Controllers can read it and use it in their tenant and trend logs.



Internal Trend LoggingIn order to retrieve and utilize these logs, a computer with Prism 2 computer software installed must be connected to the Orion Controls System. The VAV/Zone Controller continuously main-tains an Internal Trend Log, which records a fi xed set of values at an interval confi gured by the user.

There are 120 log values available. Once all 120 log values have been recorded, the oldest value is replaced by each subsequent new value. This means the user is required to retrieve the logs at an interval that is shorter than the duration of the last 120 logs. Shown below are some log intervals and the duration of 120 logs.

1 minute interval ...................... 2 hour duration15 minute interval .................... 30 hour duration30 minute interval .................... 60 hour duration60 minute interval .................... 120 hour duration

The fi xed items in the log are listed below with the column header in parentheses:

NOTE: For proper time and date stamping of the tenant log, you must confi gure the Unit Controller to broadcast the time so that the VAV/Zone Controllers can read it and use it in their tenant and trend logs.

CAUTION: These logs are subject to loss if a power outage occurs.

Internal Trend Logs & Force Modes or Overrides

Force Modes or OverridesThe VAV/Zone Controller damper can be forced to one of several positions. These force modes aid the user during troubleshooting or air balancing, etc.

Force Damper Full Open (ignores Airfl ow reading) Force Damper Full Closed (ignores Airfl ow reading) Force to Maximum Airfl ow/Damper Setpoint Force to Minimum Airfl ow/Damper Setpoint Force to Fixed Airfl ow/Damper Setpoint Force Damper to Re-Calibrate

The Force to Fixed Airfl ow/Damper Mode also has a setpoint associated with it. This allows the user to provide a non-changing fi xed amount of air into the space that doesn’t affect the mini-mum or maximum setpoints. This means the user doesn’t have to disturb the real minimum and maximum setpoints to achieve a nonstandard setting during their troubleshooting or air balanc-ing modes.

The Force to Minimum Mode uses the currently active minimum setting based on the Vent, Cooling, or Heating Modes. Whatever mode the VAV/Zone Controller is in determines the minimum used by the force mode.

The damper force modes will remain in effect until cancelled by the user or until the power is removed. Unlike the Unit Control-lers which require the initiating device to be present at all times during a force mode, the damper force modes are more permanent since they are less likely to damage any equipment. There are no force commands available for the auxiliary relays.

LED Troubleshooting

Using LEDs To Verify Operation

The VAV/Zone Controller is equipped with LEDs that can be used to verify operation and perform troubleshooting. See Figure 18. for the LED locations. The LEDs and their uses are as follows:

Operation LEDs - Factory Troubleshooting

COMM - This orange LED will light up and blink continuously to indicate communications are working properly.

POWER - This green LED will light up to indicate that 24 VAC power has been applied to the controller.

APP HB - This green LED will light up and blink continuously to indicate the application software is working properly.

Analog Space Temperature SensorIf the Space Temperature Sensor is not reading a valid tempera-ture, make sure the wiring terminal connections are tight and that any wiring splices are properly connected. You can check the operation of the Space Temperature Sensor by measuring the resistance or voltage using a digital multimeter. Set the meter to DC Volts. Place the positive probe on the AIN terminal and the negative probe on the GND terminal. Read the DC Volts and fi nd that voltage in Table 5, page 42. Read the temperature corresponding with that voltage and determine if this is close to the actual temperature the sensor is exposed to. If the tempera-ture from the chart is different by more than a few degrees, you probably have a defective or damaged sensor. You can also check the sensor resistance to determine correct operation. To read the resistance, set the meter to Ohms. Unplug the sensor connector from the board and measure the resistance across the discon-nected wires. This resistance should match the corresponding temperature from Table 5, page 42.

E-BUS Digital Room Temperature SensorIf the E-BUS Digital Room Temperature Sensor is not displaying a valid temperature, fi rst make sure that the E-BUS modular cable connector is fi rmly plugged into the E-BUS modular connector on the board and at the Temperature Sensor. If the problem persists, try swapping the sensor with a known good Room Temperature Sensor. If that sensor works when connected to the VAV/Zone Controller, you can assume you have a defective or damaged sen-sor. If you are using a terminal connector to connect the sensor, follow the instructions for the Analog Space Temperature Sensor .

Supply Air Temperature SensorIf you suspect the Supply Air Temperature Sensor is not reading correctly, make sure the wiring terminal connections are tight and that any wiring splices are properly connected. You can check the operation of the Supply Air Temperature Sensor by measuring the resistance or voltage using a digital multimeter. Set the meter to DC Volts. Place the positive probe on the AIN terminal and the negative probe on the GND terminal. Read the DC Volts and fi nd that voltage in Table 5, page 42. Read the temperature corresponding with that voltage and determine if this is close to the actual temperature the sensor is exposed to. If the temperature from the chart is different by more than a few degrees, you probably have a defective or damaged sensor. You can also check the sensor resistance to determine correct opera-tion. To read the resistance, set the meter to Ohms. Unplug the sensor connector from the board and measure the resistance across the disconnected wires. This resistance should match the corresponding temperature from Table 5, page 42.

Airflow SensorIf the Airfl ow Sensor seems to be reading incorrectly, check the Airfl ow Sensor tubing connections at the airfl ow pickup tubes. The high pressure port of the sensor needs to be connected to the upstream pickup tube. The low pressure port of the sensor needs to be connected to the downstream pickup tube.

The “Air Valve Sizing Constant” setting under the confi guration settings for the VAV/Zone Controller must be set to a number other than 0. This number is normally referred to as the “K” factor and is supplied by the terminal unit manufacturer. It represents the airfl ow through the box inlet at 1” W.G. constant static pres-sure. This factor must be entered in the confi guration screen or the airfl ow through the box will be incorrect.

If none of the procedures above solves the problem, remove power from the VAV/Zone Controller. Shut down the HVAC unit supplying the duct that the VAV/Zone damper is located on. Be sure that no airfl ow is present in the duct. Reapply power to the board and wait for the VAV/Zone Controller to run through its calibration sequence. Restart the HVAC unit and check the VAV/Zone Controller CFM readings. If the CFM reading still seems to be in error, you probably have a defective Airfl ow Sensor and will need to replace it.

TROUBLESHOOTING

Zone Damper Actuator

Check the Modular cable between the controller and the actuator. Be sure both ends of the cable are fi rmly connected to the mating connectors on the actuator and the VAV/Zone Controller. Be sure the damper moves freely and is not bound. Do this by pressing the actuator clutch button and rotating the damper shaft in both directions to verify smooth operation. If binding is present, fi x the problem as required. Remove power from the VAV/Zone Controller. Reapply power and observe the damper rotation. If the actuator does not drive the damper in both directions, the actuator is probably defective or damaged. Another test that can be performed is to swap cables with another known operating actuator to determine if the cable could be bad. If the problem goes away, you have a defective cable that must be replaced. You can also try swapping a functioning actuator with the suspected defective actuator. If this solves the problem, the defective actua-tor will need to be replaced.

Diagnostics

VAV/Zone Controller Expansion Module

If the VAV/Zone Controller Expansion Module does not seem to operate correctly, fi rst make sure the E-BUS cable between the Expansion Module and the VAV/Zone Controller is fi rmly con-nected at both ends. Be sure that the Expansion Module has been confi gured correctly. The Expansion Module must be confi gured using the Modular Service Tool SD, Modular System Manager SD, or Prism 2 computer software for your application before it will operate. You must confi gure the number of heat stages, and if it is a fan terminal you must confi gure whether it is a Series Flow or Parallel Flow Fan Terminal unit. On a single duct non-fan terminal unit when a call for heat is initiated, the LED labeled RLY2 should light up. If the Expansion Module is confi gured as a fan terminal, on a call for the fan, the LED labeled RLY1 should light up. If the LEDs do not light up, the Expansion Module is probably defective and must be replaced.

Temperature Sensor Testing

Temperature Sensor Testing

The following sensor voltage and resistance table is provided to aid in checking sensors that appear to be operating incorrectly. Many system operating problems can be traced to incorrect sen-sor wiring. Be sure all sensors are wired per the wiring diagrams in this manual.

If the sensors still do not appear to be operating or reading cor-rectly, check voltage and/or resistance to confi rm that the sensor is operating correctly per the table. Please follow the notes and instructions in Figure 19, below when checking sensors.

TROUBLESHOOTING

Single Loop VAV/Zoning

If you have a single HVAC unit that will be using VAV terminal units or are using a zoning system and don’t have any CV units you should select the Single Loop Zoning System. On a Variable Volume Variable Temperature Zoning System up to 16 VAV/Zone Controllers can be confi gured as voting zones, and additional zone controllers can be non-voting zones. For VAV systems you can have up to 58 total VAV/Zone Controllers in addition to the HVAC unit controller for the VAV boxes.

The Unit Controller(s) are connected to a MiniLink communi-cations interface which provides communications between all controllers on the local communications loop and the System Manager TS-L end-user interface, Modular System Manager SD operator interface, Prism 2 operator interface, or CommLink communication interface. The MiniLink provides for alarm poll-ing of all VAV/Zone Controllers.

Each of the controllers are connected together and to the MiniLink by means of local loop communications cable. All communication wiring must be plenum-rated, minimum 18 gauge, 2-conductor, twisted pair with shield cable. WattMaster can supply commu-nication wire that meets this specifi cation and is color coded for the network or local loop or if desired, Belden #82760 or its equivalent wire may also be used.

The System Manager TS-L is an operator interface that can be used for monitoring of the system. It has a color touch screen display and intuitive graphical user interface.

In addition or as an alternative a CommLink communication interface can be provided that allows for connection to any computer which has the free Prism 2 software installed to pro-vide for confi guring and monitoring of the system. Prism 2 is a Windows®-based color graphical computer front end software package designed by WattMaster. An optional IP Module is also available to provide Internet connectivity to the control system.

Multiple Loop VAV/Zoning

If you have a multiple HVAC units that will be using VAV Ter-minal Units or will be using a Zoning System and don’t have any CV units you should select the Multiple Loop Zoning System. On a Zoning System each local loop allows up to 16 VAV/Zone Controllers can be confi gured as voting zones, and additional controllers to be non-voting zones. For VAV systems you can have up to 58 total VAV/Zone Controllers in addition to the HVAC unit controller for the VAV boxes.

Each local loop is connected to its own MiniLink communications interface which provides communications between all control-lers on the local communications loop and the System Manager TS-L end-user interface, Modular System Manager SD operator interface, Prism 2 operator interface, and/or the CommLink com-munication interface. The MiniLink provides for alarm polling of all the zone controllers.

On this type of system the CommLink communications interface is required and acts as the main hub for all the local loops on the system and passes communications between and across all the local loops . The wiring between the CommLink and all the MiniLink devices is called the network loop

Each of the controllers on the local loops are connected together and to that loops MiniLink by means of local loop communica-tions cable. Each of the MiniLink devices are connected together and to the CommLink on the network loop using network com-munications cable. All communication wiring must be plenum-rated, minimum 18 gauge, 2 conductor, twisted pair with shield cable. WattMaster can supply communication wire that meets this specifi cation and is color coded for the network loop or local loop, or if desired, Belden #82760 or its equivalent wire may also be used.

The System Manager TS-L is an operator interface that can be used for monitoring of the entire control system. It has a color touch screen display and intuitive graphical user interface. It can be located on any local loop on the system. Multiple System Manager TS-L operator interfaces can also be used if desired.

The CommLink communication interface is standard on this type of system and allows for connection to any personal com-puter which has the free Prism 2 software installed to provide for confi guring and monitoring of the system. Prism 2 is a Windows®-based color graphical computer front end software package designed by WattMaster. An optional IP Module is also available to provide Internet connectivity to the control system.
