FX10 Microprocessor and BAS System

The FX10 is a microprocessor based control that not

only monitors and controls the heat pump but also can

communicate any of this information back to the building

automation system (BAS). This means that not only does

the control monitor the heat pump at the unit you can also

monitor and control many of the features over the BAS.

This clearly puts the FX10 in a class of its own.

The control will enumerate all fault conditions (HP, LP,

LOC, and Freeze Detection) over a BAS as well as display

them on a medium user interface (MUI). HP, LP, and Freeze

Detection faults can all be reset over a BAS. A Loss Of

Charge fault can not be reset or bypassed until the problem

has been corrected. A MUI is invaluable as a service tool for

the building service team.

The unit can be commanded to run by applying Y1, Y2, and

B commands to the terminal board or commanded through

a BAS. The control board is wired with quick connect

harnesses for easy field change out of a faulty control

board. An alarm history can be viewed through the MUI and

will be held in memory until the unit is power cycled.

The FX10 control has unused analog and digital inputs for

field installed items such as water temperature or current

status switches. The control has unused binary and PWM

outputs that can be commanded over the BAS for field use.

A Medium User Interface (MUI) for control setup and

advanced diagnostics is standard on all reversible chiller

models.

Control and Safety Feature Details Emergency Shutdown

The emergency shutdown mode can be activated by a

command from a facility management system or a closed

contact on BI-2. The default state for the emergency

shutdown data point is off. When the emergency

shutdown mode is activated, all outputs will be turned

off immediately and will remain off until the emergency

shutdown mode is de-activated. The first time the

compressor starts after the emergency shutdown mode

has been de-activated, there will be a random start delay

present.

Lockout Mode

Lockout mode can be activated by any of the following

fault signals: refrigerant system high pressure, refrigerant

system low pressure, or freeze detection. When any valid

fault signal remains continuously active for the length

of its recognition delay, the controller will go into fault

retry mode, which will turn off both compressors. After

the compressor short cycle delay, the compressors will

attempt to operate once again. If three consecutive faults

occur in 60 minutes, the unit will go into lockout mode,

turning off the compressor(s), enabling the alarm output

until the controller is reset. If the control faults due to the

low pressure input being open during the pre-compressor

startup check, the control will go into lockout mode

immediately, disabling the compressors from starting and

enabling the alarm output. The lockout condition can be

reset by powering down the controller, by a command from

the BAS, or by the holding the ESC and Return keys on the

user interface for 5 seconds. NOTE: See freeze detection section for more detail.

NXW REVERSIBLE CHILLER SPECIFICATION CATALOG

Envision Controls - FX10 cont.

Reversible Chiller Advanced Freeze Detection SystemThe reversible chiller source and load heat exchangers are

protected by a multi-sourced temperature logic strategy. The

temperature logic is based upon the refrigerant temperature

sensed as the refrigerant is about to enter the heat

exchanger; while entering and leaving water temperatures

are being used as correlating factors. The detection scheme

is shown as basic and advanced algorithms.

Basic Freeze Detection Operation: “Comp1 or Comp2 Freeze” Alarm

This alarm can be triggered by one of two detection

schemes.

Hard Limit Freeze DetectionIf the refrigerant temperature drops below the freeze

detection setpoint by 1.8°F, the associated compressor

is locked out immediately regardless of any other

factors and requires a manual reset. NOTE: This Lockout produces a “Comp 1 or Comp 2 Freeze” error on the MUI display.

Freeze DetectionThe refrigerant temperature is compared to the freeze

detection setpoint (15°F [antifreeze] or 33°F [water]

field selectable), and if the temperature falls below the

setpoint for 30 continuous seconds, the associated

compressor will be halted. This function becomes

enabled after the first two minutes of compressor

operation. Three such events in 60 minutes will trigger a

compressor lockout that requires a manual reset. NOTE: This Lockout produces a “Comp 1 or Comp 2 Freeze” error on the MUI display.

In addition to the above: Entering Water Temperature InfluenceIf the entering water temperature of the evaporative

heat exchanger is within 10°F of the freeze setpoint,

the previously mentioned two minute delay will be

eliminated. This allows the freeze detection to operate

immediately when the compressor starts based on

entering water temperature.

Leaving Water Temperature InfluenceIf the leaving water temperature of the evaporative

heat exchanger is within 10°F of the freeze setpoint, the

previously mentioned 30 second delay will begin to be

proportionately reduced, ending at a 1 second delay

when the leaving water temperature is 1.5°F above the

freeze setpoint.

Dual Circuited Heat Exchanger ProtectionA low temperature condition on either refrigerant circuit

will prevent the start of both compressors. If the low

temperature condition exists for 5 minutes when both

compressors are off, a lockout is triggered for both

compressors. However, if for instance both compressors

are operating and circuit 1 experiences a refrigerant

temperature below the freeze detection setpoint such

that compressor 1 is halted, compressor 2 will not be

halted as a result.

Advanced Freeze Detection Operation: “Pre Freeze” Alarm

Predictive freeze condition detection:If the refrigerant temperature is within 7.2°F of the

freeze detection setpoint, the predictive freeze

detection algorithm is enabled, and if the logic

determines that a freeze condition is likely to happen

based on current conditions, the compressor of the

involved refrigerant circuit is immediately stopped.

Three (3) such events in 60 minutes will trigger a

compressor lockout that requires a manual reset. In the

absence of such a condition, the compressor is allowed

to operate so that the refrigerant temperature may

eventually be at the threshold of the freeze detection

setpoint. NOTE: This Lockout produces a “Pre Freeze” detection error on the MUI display.

Capacity Limiting

If the leaving water temperature drops to 1.8°F above the

freeze detection setpoint, the lead compressor is halted.

When the leaving water temperature rises to 3.6°F above

the freeze detection setpoint, it will be allowed to resume

operation. This limiting is allowed to repeat indefinitely with

no lockout or indication on the display.

If the leaving water temperature drops to the freeze

detection setpoint, the lag compressor is halted. When the

leaving water temperature rises to 1.8°F above the freeze

detection setpoint, it will be allowed to resume operation.

This limiting is allowed to repeat indefinitely with no lockout

or indication on the display.

High Pressure

The high-pressure switch shall be a normally closed (NC)

switch that monitors the systems refrigerant pressure. If the

input senses the high-pressure switch is open it must disable

the compressor output immediately and count the fault. The

compressor minimum on time does not apply if the high-

pressure switch opens. The compressor will not restart until

the compressor short cycle time delay has been satisfied.

Page 13: Commercial Reversible Chiller - 60 Hz

13

NXW REVERSIBLE CHILLER SPECIFICATION CATALOG

Envision Controls - FX10 cont.Low Pressure

The low-pressure switch shall be a normally closed (NC)

switch that monitors the systems refrigerant pressure. The

input 15 seconds before compressor start up and then

ignored for the first 2 minutes after the compressor output

(BO-2) is enabled. If the switch is open continuously for

30 seconds during compressor operation the compressor

output (BO-2) will be disabled. The compressor will not

restart until the compressor short cycle time delay has been

satisfied.

Alarm Outputs

The control has two alarm outputs, one for each compressor

circuit. These 24VAC outputs are designated as LC1

(compressor 1) and LC2 (compressor2) on the low voltage

terminal board.

Test Mode

By holding the ESC and down arrow keys on the MUI for 5

seconds will put the control into test mode. In test mode

the random start delay and the compressor fixed on delay

time will both be shortened to 5 seconds and the reversing

valve will be allowed to cycle with out shutting down the

compressor. If an MUI is connected to the control LED 8 will

flash and the words “Test Mode Enabled” will be shown on

the LCD display when the control is in test mode. Test mode

will be disabled after a power cycle, 30 minute timeout, or

by holding the ESC and Up arrow keys on the MUI.

Sequence of OperationPower Fail Restart

When the controller is first powered up, the outputs will be

disabled for a random start delay. The delay is provided to

prevent simultaneous starting of multiple heat pumps. Once

the timer expires, the controller will operate normally.

Random Start Delay

This delay will be used after every power failure, as well as

the first time the compressor is started after the control exits

the unoccupied mode or the emergency shutdown mode.

The delay should not be less than 1 second and not longer

than 120 seconds. If the control is in test mode the random

start delay will be shortened to 5 seconds.

Lead Compressor Start Delay Time

The Lead Compressor Fixed On Delay Time will ensure that

the lead compressor output is not enabled for 90 seconds

after the control receives a call to start the compressor. This

delay is adjustable from 30 – 300 seconds over a BAS or a

MUI. If the control is in test mode the Lead Compressor Start

Delay Timer will be shortened to 5 seconds.

Lag Compressor Start Delay Time

The Lag Compressor Fixed On Delay Time will ensure that

the lead compressor output is not enabled for 90 seconds

after the control receives a call to start the compressor. This

delay is adjustable from 30 – 300 seconds over a BAS or a

MUI. If the control is in test mode the Lag Compressor Start

Delay Timer will be shortened to 5 seconds.

Compressor Minimum On Delay

The compressor minimum on delay will ensure that the

compressor output is enabled for a minimum of two (2)

minutes each time the compressor output is enabled. This

will apply in every instance except in the event the high

pressure switch is tripped or emergency shutdown then the

compressor output will be disable immediately.

Compressor Minimum Off Delay Time

The compressor minimum time delay will ensure that the

compressor output will not be enabled for a minimum of five

(5) minutes after it is disabled. This allows for the system

refrigerant pressures to equalize after the compressor is

disabled.

Compressor Lead/Lag

Compressor lead/lag is a standard part of the FX10 control

system. The unit is shipped from the factory with lead/

lag disabled. Lead/lag can be activated through the unit

mounted user interface. The default lead/lag time is 24

hours, but can be adjusted through the user interface.

Heating Cycle

The control will run the unit in heating mode when there is a

command on the O/B terminal on the terminal board.

Cooling Cycle

The control will run the unit in cooling mode when there is

no command on the O/B terminal on the terminal board.

MUI Alarm History Reporting

If a fault occurs the fault will be recorded in history for

display on the medium user interface in the History Menu.

The Closed Loop Heat Pump Concept

The basic principle of a water source heat pump is the

transfer of heat into water from the space during cooling,

or the transfer of heat from water into the space during

heating. Extremely high levels of energy efficiency are

achieved as electricity is used only to move heat, not to

produce it. Using a typical WaterFurnace Envision Series,

one unit of electricity will move four to five units of heat.

When multiple water source heat pumps are combined

on a common circulating loop, the ultimate in energy

efficiency is created: The WaterFurnace units on cooling

mode are adding heat to the loop which the units in

heating mode can absorb, thus removing heat from the

area where cooling is needed, recovering and redistributing

that heat for possible utilization elsewhere in the system. In

modern commercial structures, this characteristic of heat

recovery from core area heat generated by lighting, office

equipment, computers, solar radiation, people or other

sources, is an important factor in the high efficiency and

low operating costs of WaterFurnace closed source heat

pump systems.

In the event that a building's net heating and cooling

requirements create loop temperature extremes, Envision

Series units have the extended range capacity and

versatility to maintain a comfortable environment for

all building areas. Excess heat can be stored for later

utilization or be added or removed in one of three ways; by

ground-source heat exchanger loops: plate heat exchangers

connected to other water sources, or conventional cooler/

boiler configurations. Your WaterFurnace representative

has the expertise and computer software to assist in

determining optimum system type for specific applications.

The Closed Loop Advantage

A properly applied water source heat pump system offers

many advantages over other systems. First costs are

low because units can be added to the loop on an "as

needed basis"- perfect for speculative buildings. Installed

costs are low since units are self-contained and can be

located adjacent to the occupied space, requiring minimal

ductwork. Maintenance can be done on individual units

without system shut-down. Conditions remain comfortable

since each unit operates separately, allowing cooling in

one area and heating in another. Tenant spaces can be

finished and added as needed. Power billing to tenants

is also convenient since each unit can be individually

metered: each pays for what each uses. Nighttime and/or

weekend uses of certain areas are possible without heating

or cooling the entire facility. A decentralized system also

means if one unit should fault, the rest of the system will

continue to operate normally, as well as eliminating air

cross-contamination problems and expensive high pressure

duct systems requiring an inefficient electric resistance

reheat mode.

The Envision Approach

There are a number of proven choices in the type of

Envision Series system which would be best for any given

application. Most often considered are:

• Closed Loop/Ground-Source Systems utilize the stable

temperatures of the earth to maintain proper water source

temperatures (via vertical or horizontal closed loop heat

exchangers) for Envision Series extended range heat

pump system. Sizes range from a single unit through many

hundreds of units. When net cooling requirements cause

closed loop water temperatures to rise, heat is dissipated

into the cooler earth through buried high strength plastic

pipe "heat exchangers." Conversely if net space heating

all of the advantages of horizontal and vertical closed loop

systems. Due to the extended loop temperatures, AHRI/

ISO 13256-1 Ground Water or Ground Loop Heat Pumps are

required for this application.

In cooling dominated structures, the ground-source surface

water systems can be very cost effective especially where

local building codes require water retention ponds for short

term storage of surface run-off. Sizing requirements for the

surface water is a minimum of 500 sq. ft./ton of surface

area at a minimum depth of 8 feet. WaterFumace should be

contacted when designs for heating dominated structures

are required.

• Closed Loop/Ground Water Plate Heat Exchanger Systems utilize lake, ocean, well water or other water

sources to maintain closed loop water temperatures in

multi-unit Envision systems. A plate frame heal exchanger

isolates the units from any contaminating effects of the

water source, and allows periodic cleaning of the heat

exchanger during off peak hours.

Operation and benefits are similar to those for ground-

source systems. Due to the extended loop temperatures,

AHRI/ISO 13256-1 Ground Loop Heat Pumps are required

for this application. Closed loop plate heat exchanger

systems are applicable in commercial, marine, or industrial

structures where the many benefits of a water source heat

pump system are desired, regardless of whether the load is

heating or cooling dominated.

Envision Application Notes cont.

Closed Loop/Ground SourceSurface Water

demands cause loop heat absorption beyond that heat

recovered from building core areas, the loop temperature

will fall causing heat to be extracted from the earth. Due to

the extended loop temperatures, AHRI/ISO 13256-1 Ground

Loop Heat Pumps are required for this application.

Because auxiliary equipment such as a fossil fuel boiler

and cooling tower are not required to maintain the loop

temperature, operating and maintenance costs are very

low. Ground-source systems are most applicable in

residential and light commercial buildings where both

heating and cooling are desired, and on larger envelope

dominated structures where core heat recovery will not

meet overall heating loads. Both vertical and horizontally

installed closed-loops can be used. The land space required

for the "heat exchangers" is 100-250 sq. ft./ton on vertical

(drilled) installations and 750-1500 sq. ft./ton for horizontal

(trenched) installations. Closed loop heat exchangers can

be located under parking areas or even under the building

itself.

On large multi-unit systems, sizing the closed loop heat

exchanger to meet only the net heating loads and assisting

in the summer with a closed circuit cooling tower may be

the most cost effective choice.

• Closed Loop/Ground-Source Surface Water Systems also

utilize the stable temperatures of Surface Water to maintain

proper water source temperatures for Envision Series

extended range heat pump systems. These systems have

Page 17: Commercial Reversible Chiller - 60 Hz

• Closed Loop /Cooler-Boiler Systems utilize a closed heat

recovering loop with multiple water source heat pumps

in the more conventional manner. Typically a boiler is

employed to maintain closed loop temperatures above

60°F and a cooling tower to maintain loop temperatures

below 90°F. These systems are applicable in medium

to large buildings regardless of whether the load is

heating or cooling dominated. Due to the moderate loop

temperatures, AHRI/ISO 13256-1 Water Loop Heat Pumps

are required for this application.

GeneralReversible chiller systems may be successfully applied in a wide range of commercial and industrial applications. It is the responsibility of the system designer and installing contractor to ensure that acceptable water quality is present and that all

applicable codes have been met in these installations.

Water TreatmentDo not use untreated or improperly treated water. Equipment damage may occur. The use of improperly treated or untreated water in this equipment may result in scaling, erosion, corrosion, algae or slime. The services of a qualified water treatment specialist should be engaged to determine what treatment, if any, is required. The product warranty specifically excludes liability for corrosion, erosion or deterioration of equipment.

The heat exchangers in the units are 316 stainless steel plates with copper brazing. The water piping in the heat exchanger is steel. There may be other materials in the building’s piping system that the designer may need to take into consideration when deciding the parameters of the water quality.

If an antifreeze or water treatment solution is to be used, the designer should confirm it does not have a detrimental effect

on the materials in the system.

Contaminated WaterIn applications where the water quality cannot be held to prescribed limits, the use of a secondary or intermediate heat exchanger is recommended to separate the unit from the contaminated water.

Water QualityThe following table outlines the water quality guidelines for unit heat exchangers. If these conditions are exceeded, a secondary heat exchanger is required. Failure to supply a secondary heat exchanger where needed will result in a warranty exclusion for primary heat exchanger corrosion or

failure.

StrainersThese units must have properly sized strainers upstream of both brazed plate heat exchangers to protect them against particles in the fluid. Failure to install proper stainers and perform regular service can result in serious damage to the unit, and cause degraded performance, reduced operating life and failed compressors. Improper installation of the unit (which includes not having proper strainers to protect the heat exchangers) can also result in voiding the warranty.

Field supplied strainers with 20-40 mesh (530-1060 microns) are recommended, with 30 mesh (800 microns) being the optimum choice. The strainers selected should have a mesh open area of at least 6 square inches (39 square centimeters) for each unit being serviced by the strainer. Using strainers with a smaller amount of open area will result in the need for more frequent cleaning.

Strainers should be selected on the basis of acceptable pressure drop, and not on pipe diameter. The strainers selected should have a pressure drop at the nominal flow rate of the units; low enough to be within the pumping capacity of the pump being used.

WARNING: Must have intermediate heat exchanger when used in pool applications.

The performance standard AHRI/ASHRAE/ISO 13256-2 became effective January 1, 2000. This new standard has three ma-

jor categories: Water Loop, Ground Water, and Ground Loop.

Unit of Measure: The Cooling COPThe cooling efficiency is measured in EER (US version measured in Btuh per Watt. The Metric version is measured in a

cooling COP (Watt per Watt) similar to the traditional COP measurement.

Pump Power Correction CalculationWithin each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using

the following formula. This additional power is added onto the existing power consumption.

• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300

Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water

flow in feet of head.

ISO Capacity and Efficiency CalculationsThe following equations illustrate cooling calculations:

• ISO Cooling Capacity = Cooling Capacity (Btuh) x 3.412

• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]

The following equations illustrate heating calculations:

• ISO Heating Capacity = Heating Capacity (Btuh) x 3.412

• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]

NOTE: * When using water. Use 485 for 15% methanol/water or Environol solution.

ELT = entering load fluid temperature to heat pump

EER = cooling energy effciency (TC/KW)

LLT = leaving load fluid temperature from heat pump

PSI = pressure drop in pounds per square inch

LGPM = load flow in gallons per minuteFT HD = pressure drop in feet of head

SGPM = source flow in gallons per minuteCOP = coefficient of performance (HC/KW x 3.413)

SWPD = source heat exchanger water pressure dropHC = heating capacity in MBTUHHE = heat of extraction in MBTUH

Notes to Performance Data Tables

The following notes apply to all performance data tables:Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water •

systems with a minimum of 50°F EST. The middle flow rate shown is the minimum geothermal closed loop flow rate.

The highest flow rate shown is optimum for geothermal closed loop systems and the suggested flow rate for boiler/

tower applications.

Entering water temperatures below 40°F assumes 15% antifreeze solution. •

Interpolation between ELT, EST, and GPM data is permissible. •

Operation in the gray areas is not recommended.•

Catalog performance can be corrected for antifreeze use. Please use the following table and note the example given.

Antifreeze Correction ExampleAntifreeze solution is Propylene Glycol 20% by weight for the source and Methanol 10% for the load. Determine the

corrected heating at 30°F source and 90°F load as well as pressure drop at 30°F for an Envision Series NXW120. Also,

determine the corrected cooling at 90°F source and 50°F load.

The corrected heating capacity at 30°F/90°F would be:

113.1 MBtuh x 0.913 x 0.986 = 101.8 MBtuh

The corrected cooling capacity at 90°F/50°F would be:

125.9 MBtuh x 0.969 x 0.961 = 117.2 MBtuh

The corrected pressure drop at 30°F and 30 GPM would be:

3.8 psi x 1.270 = 4.8 psi

source liquid temperatures between 30°F [1.1°C] and 110°F

[43.3°C] in cooling, and between 20°F [-6.7°C] and 90°F

[32.2°C] in heating.

Factory Quality

Each unit shall be run tested at the factory using water.

Quality control system shall automatically perform via

computer: triple leak check, pressure tests, evacuate and

accurately charge system, perform detailed heating and

cooling mode tests, and quality cross check all operational

and test conditions to pass/fail criteria. Units tested

without water flow are not acceptable. The units shall be

warranted by the manufacturer against defects in materials

and workmanship for a period of 12 months from startup or

18 months from shipment.

enclosure shall be factory installed. The optional

acoustical enclosure shall be constructed of heavy

gauge G60 galvanized sheet metal (Top panel – 18

gauge, Corner panels – 18 gauge, and side panels – 20

gauge) and polyester, powder coated, gloss white.

Paint shall be rated for 1,000 hours of salt spray using

ASTM B117. All panels shall be lined with 1/2 inch [12.7

mm] thick, 1-1/2 lb./cu. ft. density, acoustic type, glass

fiber insulation. All insulation must meet NFPA 90A.

This material shall also provide acoustical benefit. The

unit must have a minimum of three access panels for

serviceability of the compressor compartment. Units

having only one access panel to compressor/heat

exchangers/expansion device/refrigerant piping shall

not be acceptable.

The control box shall have separate holes and knockouts

for entrance of line voltage and low voltage control

wiring. All factory-installed wiring passing through factory

knockouts and openings shall be protected from sheet

metal edges at openings by plastic ferrules.

Refrigerant Circuit

All units shall contain 2 sealed refrigerant circuits, each

containing a hermetic motor scroll compressor,

bidirectional, thermal expansion valve assemblies, reversing

valve, braze plate heat exchangers, factory installed high

and low pressure safety switches, freeze detection, service

ports, and liquid line filter dryers. Compressors shall be

designed for heat pump duty with internal isolation and

mounted on rubber vibration isolators. Compressor motors

shall have internal overload protection. A high density

sound attenuating blanket shall be factory installed around

the compressor to reduce sound. The water to refrigerant

heat exchangers shall be interlaced copper-brazed and

316 stainless steel plate, capable of withstanding 650

psig [4489 kPa] working pressure on the refrigerant side

and 450 psig [3108 kPa] on the water side. The thermal

expansion valve assembly shall provide proper superheat

over the liquid temperature range with minimal “hunting.”

The assembly shall operate bidirectionally without the use

of check valves. Externally mounted pressure controlled

water regulating flow valves are not acceptable.

Piping and Connections

The units shall have one set of water in and water out

connections (heat exchangers are internally piped in

parallel). The connection shall be a 2 in. [50.8 mm] Victaulic

type grooved mechanical fitting. Grooved couplings shall

meet the requirements of ASTM F-1476. Pipes shall be

carbon steel, A-53B/A-106B. Pipe ends to be grooved in

accordance with standards conforming to ANSI/AWWA

C-606. Coupling shall be cast of ductile iron conforming to

ASTM A-536, Grade 65-45-12 or malleable iron conforming

to ASTM A-47, Grade 32510. Gaskets shall be Grade “E”

EPDM compound conforming to ASTM D-2000 Designation

2CA615A25B24F17Z.

Electrical

Controls and safety devices will be factory wired and

mounted within the unit. Controls shall include 24 Volt

activated compressor contactors, 24VAC-75VA transformer

with built in circuit breaker, reversing valve coils, and

anti short-cycle protection. A terminal block with screw

in terminals will be provided for field control wiring.

To prevent short cycling when the safety controls are

activated, the reset relay shall provide a lockout circuit that

requires resetting of low voltage supply or main circuit

breaker. A lockout signal shall be provided to the display

to indicate a lockout situation. Units shall be name-plated
