With both the Modular Service Tool and the Modular System ManagerYou must enter the ID (Address) of the controller you wish to program

Unit Selection Enter Unit ID# Selected ID#: xxxx

With the main menu screen displayed, press the function key associatedwith the operation (setpoints, configuration, etc.) you want to perform.The screen shown above will appear asking you to enter a unit I.D.#(controller address). Put in the ID# of the controller you wish to com-municate with then press the “ENTER” key.

If this is Multiple Loop Network System the Unit ID is actually twoseparate numbers, combined into one value. The first part of the num-ber contains the Loop Address at which the controller is located. Thesecond part of the number contains the actual controller address. SeeExamples #1 & #2 below.

EXAMPLE #1You would like to view the 3rd controller on the 5th loop. Enter “503”as the Unit ID.

EXAMPLE #2You would like to view the 12th controller on the 24th loop. Enter “2412”as the Unit ID

EXAMPLE #3You would like to view the only controller on the loop. Enter 1 as theUnit ID. No loop number is required since there is only one loop.

Hit the “Enter” key after entering the unit ID. If you are using the ModularService Tool you will be taken directly to the first screen for the opera-tion you are trying to program.


System Manager Initialization Screens

When the System Manager is powered up, the first screen displays thecurrent version of the software installed in your System Manager andwhether your system is configured for Network or Stand-Alone opera-tion. On a Networked System, all controllers on the communicationsloop are available for programming by entering their loop address (ID).

If the System Manager is configured for Stand-Alone operation, onlythe HVAC unit controller that the System Manger is connected to isavailable for programming. The Stand-Alone feature is only used forservicing and testing. For normal operation the System Manager mustbe configured for Network mode.

The screen above will appear a few seconds later. The last line of thedisplay will have the letters SA (Stand Alone Mode), MM (MultipleSystem Manager Mode) or NM (Network Mode) followed by the cur-rent outdoor air temperature. The System Manager normally ships fromthe factory set for NM (Network Mode). If you have only one SystemManager, the system must be set for NM (Network Mode). If you havemultiple System Managers on your system, the system must be set forMM (Multiple System Managers Mode). If you believe your system isincorrectly configured, please follow the instructions that follow. If yoursystem is configured correctly, proceed to the System Manager Net-work Mode Loop

Configuring For Stand-Alone Mode, MultipleSystem Managers Mode or Network Mode

As previously described the System Manager must be configured forthe correct mode of operation for your system. Again, there are 3 modesof operation available for the WattMaster VAV System. They are “StandAlone Mode”, “Multiple MGRS Mode” or “Network Mode”.

Look at the bottom line of the display as mentioned in the previousparagraph and determine which one your System Manager is currentlyset for. If you have a single System Manager for your entire system,then you need to operate in “Network Mode” and the first two charac-ters on the bottom line of the display should be “NM”. If you havemultiple System Managers on your system then you need to operate in“Multiple MGRS Mode” and the first two characters on the bottomline of the display should be “MM”. The System Manager should neverbe set to “Stand-Alone” mode unless you have been instructed to con-figure this setting by WattMaster Technical Support.

If your display indicates a different mode than the one you need, pressthe “Enter” key and the following screen will appear.

Modular Service ToolThe Modular Service Tool is very similar to the System Manager in itsoperations as stated previously. Two exceptions to this are that the Ser-vice Tool unlike the System Manager does not check the entire systemwhen performing an “Alarm” or “Override” search and it does not haveany passcoding capability.

Note: When the Alarms or Overrides buttons are pressed onthe Modular Service Tool it will search only the loopnumber of the unit ID that has been entered, thereforeeach local loop must be searched individually to accessall alarms or overrides on the system.

The WMVAV controller does not require that you start configuring yourheating or cooling stages first and it doesn’t require that you utilizeconsecutive relays until all heating or cooling stages have been defined.All relays can be used for any of the above options in any order youdesire. This method allows the greatest flexibility in the field, but itrequires close attention to the wiring of the heating and cooling stagesto prevent incorrect and possibly harmful operation.

The controller assumes there will only be one relay configured for Morn-ing Warm-up Mode although it doesn’t prevent multiple relays frombeing selected. Since this relay is used to send a signal to VAV boxes todrive to their maximum airflow position, redundant relays are not re-quired.

Relays #2 through #21 can be individually configured. This should beenough to handle up to 8 stages of heating and 8 stages of cooling onlarge HVAC units. Only the heating and cooling relays can be config-ured with multiple outputs. If any other option is selected more thanonce, it will simply activate redundant relays but no multiple stagingwill occur.

If you used a 1.5 multiplier and the optimal start hadcalculated a 30 minute pre-start, the soak multiplier would add an ad-ditional 15 minutes to the pre-start for a total of 45 minutes (1.5 x 30).The system would then start 45 minutes earlier than the normally sched-uled occupied mode schedule to bring the space temperature undercontrol.

WMVAV Schd ID 59 Sunday Event #2 Start Time..: xxxx Stop Time..: xxxx

If you are using the internal scheduling capability of the WMVAV con-troller, set the schedule hours and holiday periods from the menu shownabove. You can also force the unit to operate continuously in occupiedor unoccupied mode by selecting the Schedule Override menu item andentering the desired command.

If you are using an external contact closure to signal the occupied mode,you must access the Week Schedule screens and set all start and stoptimes to zero to prevent the internal schedule from bringing the equip-ment on when you don’t want it to operate.

The screens will step through the Start Time and then the Stop Time foreach day of the week. You can quit at any point in the process by press-ing the “Escape” key. There are two Start/Stop events available per dayso the screen will show which event is being programmed. If you needonly one event, leave Event #2 times to ZERO.

All times are in 24-hour military format, so 5:00 PM would be enteredas 1700.

If both the Start and Stop Times are ZERO, the schedule is in a continu-ous OFF mode. (Use for Remote Signal Contact)

If both the Start and Stop Times are 2359, the schedule is in a continu-ous ON mode.

Note: The second line displays which day of the week is cur-rently being programmed. This automatically incrementsas you finish the Event #2 screen and continue to thenext days Event #1 screen.

Caution: The controller ships with all schedules set to zero sothat the controller will not attempt to heat or coolbefore the user has configured his system.

HC Box Spts IDxxxx Damper/Airflow SptIntegral [Ki]..: xxx

The Box Controller normally opens it’s damper based on a ProportionalError from Setpoint. That means if the zone temperature is 4°F fromsetpoint, the damper would be 100% open or it would be modulating toprovide the Maximum CFM on Pressure Independent boxes. If the er-ror is less than 4°F, the damper may stagnate at that position and neversatisfy the zone. If you add Integral into the damper calculation pro-cess, this will cause the damper or airflow calculations to continue toincrease as long as the zone temperature is still above the setpoint. Thatmeans it can provide 100% or Maximum CFM before the 4°F error isachieved, bringing the zone under control faster than it normally would.Start with a small ( 5 or 10 ) value, if you use this, and monitor the effectit has. If you enter too large a value, you can create “hunting” situationsthat can cause the damper actuator to prematurely wear out.

HC Box Spts IDxxxx Damper/Airflow SptNt/Rh Min.: xxx %Fan On Min: xxx %

The Nt/Rh Min (Night or Reheat Minimum Damper Position) has dif-ferent functions depending on whether the VAVBOX controller is inthe occupied or unoccupied mode and whether the VAVBOX controlleris used on a fan powered or non-fan powered terminal unit.

Occupied ModeIf the VAVBOX controller is used on a non-fan-powered terminal unitthat has reheat, the VAVBOX damper will move to the Nite/Reheat po-sition whenever a Space Heating demand occurs and the HVAC unit isin Supply Air Cooling or Vent modes. When the HVAC unit is in Sup-ply Air Heating mode the VAVBOX damper will modulate as requiredto maintain the Space Heating setpoint. This setting has no effect on fanpowered terminal units when they are in the occupied mode.

Unoccupied ModeWhen using non-fan powered terminal units, the VAVBOX damper willposition itself in the Nite/Reheat minimum position. In order for fanpowered terminal units to position the damper to the Nite/Reheat mini-mum position, the check for main fan status must be selected and theHVAC unit fan must be operating.

The Fan On Min is used for Parallel Fan boxes only. This is the damperposition that will cause the Parallel Fan to start if the damper/airflowdrops below this value. Normally the Parallel Fan only operates whenthe Reheat stages are activated. If this is not a Parallel Fan box, the lastline will remain blank. Series Fan boxes are not affected by this settingas the fan is always on anytime the HVAC unit fan is running.

Damper Force ModesDamper Force Modes are available for testing or balancing the system.These Force Modes can be accessed and programmed from either theSystem Manager or the Modular Service Tool.

System Manager InstructionsTo access the Damper Force Modes from the System Manager, pressthe “Setpoints” key. You will then see the unit ID screen. Enter the unitID of the controller you wish to access and press "Enter". The followingscreen will appear.


Press “3” on the keypad and then the "Enter" key. You will then see theunit ID screen. Enter the unit ID of the controller you wish to accessand press "Enter". At this time the password screen will be displayed.Enter your level 2 password. Press "Enter" and the damper force modesscreen will be displayed.


Press the “2” key to access the Damper Force Modes screen. OutputsForce is not available with the System Manager.

Modular Service Tool InstructionsWhen using the Modular Service Tool simply press the “Balance-Test”key. You will then see the unit ID screen. Enter the unit ID of the con-troller you wish to access and press "Enter". The damper force modesscreen will be displayed.


Press the “2” key to access the Damper Force Modes screen. OutputsForce is available with the Modular Service Tool but is not used withthe VAVBOX controller.

Damper Force Mode ScreensIf the unit ID you entered is for a WMVAV controller that has VAVBOXcontrollers connected to its communication loop, the Damper ForceMode will act as a “Global” Damper Force Mode. That is, all VAVBOXcontrollers on that WMVAV controllers communication loop will beforced to the same Damper Force Mode setting. If the unit ID you en-tered is for a VAVBOX controller, the Damper Force Mode setting willonly apply to that VAVBOX controller.

Damper Force ID 159Enter Force Mode.: 00=Auto 1=Open 2=Clsd 3=Max 4=Min 5=Fixd

Set the appropriate Damper Force Mode by entering numbers 0 through5. The Force Modes for each of these settings is outlined below.

0 = Auto This is the default setpoint. With this settingthe damper will operate normally and modulateaccording to the controller setpoints.

1= Open This setting will force the dampers to their fullyopen position.

2= Clsd This setting will force the damper to it’s fullyclosed position.

3= Max This setting will force the damper to the dampersmaximum airflow position set under SetpointScreen #4

4= Min This setting will force the damper to the currentmodes, minimum position setpoint. These modesare Vent Mode, Heat Mode and Cool Mode. Theymay each have a different minimum depending onhow you configured the setpoints.

5=Fixd This setting will force the damper to a fixedposition based on the fixed position setpoint.

See VAVBOX controller Setpoint Screen #7 foravailable setpoint information.

Caution: The Damper Force Modes should only be used by quali-fied service personnel. Serious damage to the ductworkcould result if the dampers are all forced closed andthe HVAC unit fan is operating.

Programming The MiniLink PD

ConfigurationIn order to correctly setup the MiniLink PD you must first configureseveral parameters in regard to the type of system and operating param-eters for the system it is installed on. Most of these values and operatingparameters are only set once, at the initial system setup and are neverchanged.

System Manager InstructionsFrom any menu screen press the “Setpoint” key. The unit selection screenwill appear requesting that you enter the unit ID number. All MiniLinkPDs are set at address 60. Enter the correct unit loop number for theloop the MiniLink Polling Device is connected to (Loop 1 you wouldenter 1) and then enter 60. Press the “Enter” key. You will see thescreen shown below.


Press “2” on the keypad to enter the first unit configuration screen.

Modular Service Tool InstructionsFrom any menu screen press the “Configuration” key. The unit selec-tion screen will appear requesting that you enter the unit ID number.Enter the correct unit ID number of the controller you want to configureand hit the “Enter” key. You will then see unit configuration screen #1.


Polling Unit Config Last Polled Zone Address: xx [Enter Last Zone]

Enter the address of the last controller (largest address number) for thelocal loop the MiniLink PD is connected to.


Polling Unit Config Optimal Start Zone Target Unit: xx [Enter Target Zone]

This is the unit ID of the Zone that you want to be satisfied by thenormally scheduled start time. If you enter “-1” into this box it willaverage all zones instead of picking a specific zone. If you do not re-quire optimal start enter “0”.

Configuration Screen #3-62

Polling Unit ConfigEnable Alarm Polling Unit xx : YES [0=NO 1=YES]

Enabling Alarm Polling for the controller whose unit ID you have en-tered, allows any alarm from that controller to be polled and reported bythe MiniLink Polling Device. If alarming is enabled when an alarmcondition is encountered, the alarm light on the System Manager willbe lit and the various alarms can be displayed for that controller at theSystem Manager by pressing the “Alarms” button. You must configurethis setting to “YES” for each controller on the loop that you wish toreceive alarms from.
