General Installation Information

Safety Considerations

WARNING: Before performing service or maintenance operations on a system, turn off main

power switches to the indoor unit. If applicable, turn off the accessory heater power switch. Electrical shock could cause personal injury.

Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualiﬁ ed service personnel should install, repair or service heating and air conditioning equip- ment. Untrained personnel can perform the basic maintenance functions of cleaning coils and cleaning and replacing ﬁ lters. All other operations should be performed by trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a ﬁ re extinguisher available.

Moving and Storage

Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packaging. Do not stack more than three units in total height. Vertical units may be stored one upon another to a maximum height of two units. Do not attempt to move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage.

Unit Location

Locate the unit in an indoor area that allows for easy removal of the ﬁ lter and access panels. Location should have enough space for service personnel to perform maintenance or repair. Provide sufﬁ cient room to make water, electrical and duct connection(s). If the unit is located in a conﬁ ned space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be difﬁ cult to remove after the unit is installed should be removed prior to setting the unit. On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. Care should be taken when units are located in

unconditioned spaces to prevent damage from frozen water lines and excessive heat that could damage electrical components.

Installing Vertical Units

Prior to setting the unit in place, remove and discard the compressor hold down

shipping bolt located at the front of the compressor mounting bracket. Vertical units are available in left or right air return conﬁ gurations. Top air dis- charge vertical units should be mounted level on a vibration absorbing pad slightly larger than the base to provide isolation between the unit and the ﬂ oor. It is not necessary to anchor the unit to the ﬂ oor (see right). Bottomﬂ ow units should be mounted level and sealed well to ﬂ oor to prevent air leakage. Bottomﬂ ow units require the supply air opening to be cut at least 1/2˝ larger than the unit’s air outlet. Protect the edges of combustible ﬂ ooring with sheet metal over-wrap or other non-combustible material.

2” Extruded Polystyrene

ENVISION RESIDENTIAL INSTALLATION MANUAL

Installing Horizontal Units

Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket prior to setting the unit in place. Horizontal units are available with side or end discharge. Horizontal units are normally suspended from a ceiling by six 3/8-inch diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits furnished with each unit. Lay out the threaded rods per the dimensions below. Assemble the hangers to the unit as shown. Securely tighten the brackets to the unit using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to the bracket, a double nut is required since vibration could loosen a single nut. To allow ﬁ lter access, one bracket on the ﬁ lter side should be installed 180° from the position shown in the ﬁ gure below. The unit should be pitched approximately 1/4-inch towards the drain in both directions to facilitate the removal of condensate. Use only the bolts provided in the kit to attach hanger brackets. The use of longer bolts could damage internal parts. Some residential applications require the installation of horizontal units on an attic ﬂ oor. In this case, the unit should be set in a full size secondary drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible condensate overﬂ ow or water leakage damage to the ceiling. The secondary drain pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration absorbing material.

CAUTION: Do not use rods smaller than 3/8-inch diameter since they may not be strong enough to support the unit. The rods must be securely anchored to the ceiling.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Duct System

An air outlet collar is provided on vertical top air discharge units and all horizontal units to facilitate a duct connection (vertical bottomﬂ ow units have no collar). A ﬂ exible connector is recommended for discharge and return air duct connec- tions on metal duct systems. Uninsulated duct should be insulated with a minimum of 1-inch duct insulation. Application of the unit to uninsulated ductwork in an unconditioned space is not recommended as the unit’s performance will be adversely affected.

If the unit is connected to existing ductwork, check the duct system to ensure that it has the capacity to accommodate the air required for the unit application. If the duct is too small, as in the replacement of heating only systems, larger ductwork should be installed. All existing ductwork should be checked for leaks and repaired if necessary. The duct system should be sized to handle the design airﬂ ow quietly and efﬁ ciently. To maximize sound attenuation of the unit blower, the supply and return plenums should include an internal duct liner of ﬁ berglass or constructed of ductboard for the ﬁ rst few feet. On systems employing a sheet metal duct system, canvas connectors should be used between the unit and the ductwork. If air noise or excessive airﬂ ow is a problem, the blower speed can be changed.

CAUTION: Be sure to remove the shipping material from the blower discharge before connecting ductwork.

Water Piping

The proper water ﬂ ow must be provided to each unit whenever the

Figure 4: Swivel Connections (Residential Units)

unit operates. To assure proper ﬂ ow, use pressure/temperature ports to determine the ﬂ ow rate. These ports should be located at the supply and return water connections on the unit. The proper ﬂ ow rate cannot be accurately set without measuring the water pressure drop through the refrigerant-to-water heat exchanger. All source water connections on commercial units are ﬁ ttin g s that accept a male pipe thread (MPT). Insert the connectors by hand, then tighten the ﬁ tting with a wrench to provide a leakproof joint. When con- necting to an open loop (groundwater) system, thread any copper MPT

Locking Ring

Gasket Support Sleeve

ﬁ tting into the connector and tighten in the same manner as described above. All source water connections on residential units are swivel piping ﬁ ttings (see Figure 4) that accept a 1-inch male pipe thread (MPT) . The swivel connector has a rubber gasket seal similar to a rubber hose gasket, which when mated to the ﬂ ush end of any 1-inch threaded pipe provides a leak-free seal without the need for thread sealing tape or compound. Check to ensure that the rubber seal is in the swivel connector prior to attempting any connection. The rubber seals are shipped attached to the waterline. To make the connection to a ground loop system, mate the brass connector (supplied in CK4L connector kit) against the rubber gasket in the swivel connector and thread the female locking ring onto the pipe threads, while maintaining the brass connector in the desired direction. Tighten the connectors by hand, then gently snug the ﬁ tting with pliers to provide a leak-proof joint. When connecting to an open loop (ground water) system, thread any 1-inch MPT ﬁ tting (SCH80 PVC or copper) into the swivel connector and tighten in the same manner as noted above. The open and closed loop piping system should include pressure/temperature taps for serviceability. Never use ﬂ exible hoses smaller than 1-inch inside diameter on the unit. Limit hose length to 10 feet per connection. Check carefully for water leaks.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Water Quality

In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualiﬁ ed service mechanic, as special solutions and pumping equipment are required. Desuperheater coils can likewise become scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional ﬂ ushing.

Units with cupronickel heat exchangers are recommended for open loop applications due to the increased resistance to build-up and corrosion, along with reduced wear caused by acid cleaning.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Freeze Protection

Set the freeze sensing switch SW2-2 on the printed circuit board for applications using a closed loop antifreeze solution

to “LOOP”. On applications using an open loop/ground water system (or closed loop no antifreeze), set this dip switch to “WELL”, the factory default setting. (Refer to the Dip Switch Field Selection table on page 24.)

Condensate Drain

On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a

3/4-inch PVC female adapter and a ﬂ exible connecting hose. The female adapter may exit either the front or the side of the cabinet. The adapter should be glued to the ﬁ eld-installed PVC condensate piping. On vertical upﬂ ow units, a condensate hose is inside all cabinets as a trapping loop; therefore, an external trap is not necessary. On horizontal units, a PVC stub is provided for condensate drain piping connection. An external trap is required (see below). If a vent is necessary, an open stand pipe may be applied to a tee in the ﬁ eld-installed condensate piping.

Closed Loop Ground Source Systems

Note: For closed loop systems with antifreeze protection, set SW2-2 to the “loop” position (see table on page 28).

Once piping is completed between the unit, pumps and the ground loop (see ﬁ gure below), ﬁ nal purging and charging of the loop is required. A ﬂ ush cart (or a 1.5 HP pump minimum) is needed to achieve adequate ﬂ ow velocity in the loop to purge air and dirt particles from the loop itself. Antifreeze solution is used in most areas to prevent freezing. Flush the system adequately to remove as much air as possible then pressurize the loop to a static pressure of 40-50 PSI (summer) or 50-75 PSI (winter). This is normally adequate for good system operation. Loop static pressure will ﬂ uctuate with the seasons. Pressures will be higher in the winter months than during the cooling season. This ﬂ uctuation is normal and should be considered when initially charging the system.

After pressurization, be sure to open the plug 1 turn in the end of the loop pump motor(s) (if applicable) to allow trapped air to be discharged and to ensure that the motor housing has been ﬂ ooded. Ensure that the loop pumps provide adequate ﬂ ow through the unit(s) by checking the pressure drop across the heat exchanger and comparing it to the unit capacity data in the speciﬁ cation catalog. 2.5 to 3 GPM of ﬂ ow per ton of cooling capacity is recommended in earth loop applications.

Multiple Units on One Flow Center

When two units are connected to one loop pumping system, pump control is automatically achieved by connecting the SL terminals on connector P2 in both units with 2-wire thermostat wire. These terminals are polarity dependant (see Figure 8). The loop pump(s) may be powered from either unit, whichever is more convenient. If either unit calls, the loop pump(s) will automatically start. The use of two units on one ﬂ ow center is generally limited to a total of 20 GPM capacity.

Open Loop Ground Water Systems

Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Insure proper water ﬂ ow through the unit by checking pressure drop across the heat exchanger and comparing it to the ﬁ gures in unit capacity data tables in the speciﬁ cation catalog. 1.5-2 GPM of ﬂ ow per ton of cooling capacity is recommended in open loop applications. Due to only minor differences in ﬂ ow rate from low to high, only one solenoid valve should be used. The valve should be sized for full ﬂ ow .

Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local codes, i.e. recharge well, storm sewer, drain ﬁ eld, adjacent stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal. Consult your local building and zoning departments to assure compliance in your area.

Note: For open loop/groundwater systems or systems that do not contain an antifreeze solution, set SW2-Switch #2 to the “WELL ” position. (Refer to the table on page 28.) Slow opening/closing solenoid valves ( type VM) are recommended to eliminate water hammer.

Desuperheater Connections

To m a x i m i ze t h e b e n e ﬁ ts of the desuperheater a minimum 50- gallon water heater is recommended. For higher demand applications, use an 80 -gallon water heater or two 50 -gallon water heaters connec ted in a series as shown below. Electric water heaters are recommended. Make sure all local electrical and plumbing codes are met for installing a desuperheater.

Note: Under certain conditions, Envision dual capacity units operate with very low refrigerant discharge temperatures, producing little or no water heating capability. This scenario occurs when the unit is operating with cold entering source water (loop or well). Allowing the desuperheater pump to operate during these conditions actually removes heat from the DHW circulating through the unit. To overcome this, En vision unit microprocessors have been programmed to disengage the desuperheater pump during such conditions. (Dur ing low capac ity c ooling oper ation, the pump will operate only if the DHW temperature entering the unit is less than the liquid line temperature plus 35º F. During high capacity cooling operation, the pump will operate only if the DHW temperature is less than the l i quid line t emperature plus 60º F.) Using a preheat tank, as shown in Figure 12, will maximize desuperheater capabilities.

Water Tank Preparation

To install a unit with desuperheater, follow these installation guidelines.

Turn off the power to the water heater.

1. Attach a water hose to the water tank drain connection and run the other end of the hose to an open drain or

2. outdoors. Close the cold water inlet valve to the water heater tank.

3. Drain the tank by opening the valve on the bottom of the tank, then open the pressure relief valve or hot water

4. faucet. Flush the tank by opening the cold water inlet valve to the water heater to free the tank of sediments. Close when

5. draining water is clear. Disconnect the garden hose and remove the drain valve from the water heater.

6. Refer to Plumbing Installation and Desuperheater Startup on page 12.

Residential units with desuperheaters contain an internal circulator and ﬁ ttings.

CAUTION: Elements will burn out if energized dry.

Plumbing Installation

1. Inspect the dip tube in the water heater cold inlet for a check valve. If a check valve is present it must be removed or damage to the desuperheater circulator will occur.

2. Remove drain valve and ﬁ tti n g .

3. Thread the 3/4-inch NPT x 3-1/2-inch brass nipple into the water heater drain port.

4. Attach the center port of the 3/4-inch FPT tee to the opposite end of the brass nipple.

5. Attach the 1/2-inch copper to 3/4-inch NPT adaptor to the side of the tee closest to the unit.

6. Install the drain valve on the tee opposite the adaptor.

7. Run interconnecting tubing from the tee to DHW water out.

8. Cut the cold water “IN” line going to the water heater.

9. Insert the reducing solder tee in line with cold water “IN” line as shown.

10. Run interconnecting copper tubing between the unit DHW water “IN” and the tee (1/2-inch nominal). The recommended maximum distance is 50 feet.

11. To prevent air entrapment in the system, install a vent coupling at the highest point of the interconnecting lines.

12. Insulate all exposed surfaces of both connecting water lines with 3/8-inch wall closed cell insulation. Note: All plumbing and piping connections must comply with local plumbing codes

Desuperheater Startup

1. Close the drain valve to the water heater.

2. Open the cold water supply to the tank.

3. Open a hot water faucet in the building to bleed air from the system. Close when full.

4. Open the pressure relief valve to bleed any remaining air from the tank, then close.

5. If so equipped, unscrew the indicator plug 1 turn on the motor end of the pump until all air is purged from the pump, then tighten the plug. Use vent couplings to bleed air from the lines.

6. Carefully inspect all plumbing for water leaks and correct as required.

7. Before restoring electrical supply to the water heater, adjust the temperature setting on the tank.

• On tanks with both upper and lower elements, the lower element should be turned down to the lowest setting, approximately 100°F. The upper element should be adjusted to 120°F to 130°F. Depending upon the speciﬁ c needs of the customer, you may want to adjust the upper element differently.

• On tanks with a single element, lower the thermostat setting to 120°F.

8. After the thermostat(s) is adjusted, replace the access cover and restore electrical supply to the water heater.

9. Make sure that any valves in the desuperheater water circulating circuit are open.

10. Turn on the unit to ﬁ rst stage heating.

11. The DHW pump should be running. When the pump is ﬁ rst started, open the inspection port 1 turn (if equipped) until water dribbles out, then replace. Allow the pump to run for at least ﬁ ve minutes to ensure that water has ﬁ lled the circulator properly. Be sure the switch for the DHW pump (SW4) is “ON”. The DHW “OFF” LED on the unit should not be illuminated.

12. The temperature difference between the water entering and leaving the desuperheater should be 5°F to 15°F. The water ﬂ ow should be approximately 0.4 GPM per ton of nominal cooling.

13. Allow the unit to heat water for 15 to 20 minutes to be sure operation is normal.

CAUTION: Never operate the DHW circulating pump while dry. If the unit is placed in operation before the desuperheater piping is connected, be sure that the pump switch is set to the OFF position.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Microprocessor Control

Startup

The unit will not operate until all the inputs and safety controls are checked for normal conditions. At ﬁ rst power-up, a four-minute delay is employed before the compressor is energized.

Component Sequencing Delays

Components are sequenced and delayed for optimum space conditioning performance.

Accessory Relay

An accessory relay on the control board allows for ﬁ eld connection of solenoid valves, electronic air cleaners, etc. The accessory relay has a normally open output and a normally closed output.

Short Cycle Protection

The control employs a minimum "off" time of four minutes to provide for short cycle protection of the compressor.

Condensate Overﬂ ow Protection

The Envision control board incorporates an impedance sensing liquid sensor at the top of the drain pan. Upon a continuous 30-second sensing of the condensate, compressor operation is suspended (see Fault Retry), and the condensate overﬂ ow lockout LED begins ﬂ ashing.

Shutdown Mode

A 24VAC common signal to the “shutdown” input on the control board puts the unit into shutdown mode. Compressor, hot water pump and fan operation are suspended.

Safety Controls

The Envision control receives separate signals for a high pressure switch for safety, a low pressure switch to prevent loss of charge damage, and a low suction temperature thermistor for freeze sensing. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended, the appropriate lockout LED begins ﬂ ashing. (Refer to the "Fault Retry" section below.)

Testing

The Envision control allows service personnel to shorten most timing delays for faster diagnostics. (Refer to the Field Selection DIP switch SW2-1 on page 24.)

Fault Retry

All faults (except for low RPM faults with the ECM2 fan motor) are retried twice before ﬁ nally locking the unit out. An output signal is made available for a fault LED at the thermostat. The “fault retry” feature is designed to prevent nuisance service calls.

Diagnostics

The Envision control board allows all inputs and outputs to be displayed on the LEDs for fast and simple control board diagnosis. (Refer to the Field Selection DIP Switch SW2-1 on page 24.)

Resistance Heat Control (208-230 Units)

The electric heat control module contains the appropriate high-voltage control relays. Control signals energize the relays in the proper sequence, and the LED display board indicates which stages are energized.

Hot Water High Limit (Domestic Hot Water Option)

This mode occurs when the hot water input temperature is at or above 130°F for 30 continuous seconds. The DHW limit status LED on the unit illuminates and the hot water pump de-energizes. Hot water pump operations resume on the next compressor cycle or after 15 minutes of continuous compressor operation during the current thermostat demand cycle.

Hot Water Justiﬁ ca tion

Since compressor hot gas temperature is dependant on loop temperature in cooling mode, loop temperatures may be too low to allow proper heating of water. The control will monitor water and refrigerant temperatures to determine if conditions are satisfactory for heating water. The DHW limit status LED on the unit illuminates when conditions are not favorable for heating water.

Heating Operation

Heat, 1st Stage (Y1)

The fan motor is started on low speed immediately (PSC ON), the loop pump is energized 5 seconds after the “Y1” input is received, and the compressor is energized on low capacity 10 seconds after the “Y1” input. The fan is switched to medium speed 15 seconds after “Y1” input (ECM only). The hot water pump is cycled 30 seconds after the "Y1" input.

Heat, 2nd Stage (Y1,Y2) Single-Speed Units

The hot water pump is de-energized, which directs all heat to satisfying the thermostat, and the fan changes to high speed 15 seconds after the "Y2" input (ECM only).

eat, 2nd Stage (Y1,Y2) Dual Capacity Units

The Comfort Alert will delay the second stage compressor until 5 seconds after it receives a “Y2” from the board.

Heat, 3rd Stage (Y1,Y2,W) Single-Speed Units

The ﬁ rst stage of resistance heat is energized 10 seconds after “W” input, and with continuous 3rd stage demand, the additional stages of resistance heat engage sequentially every 5 minutes.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Microprocessor Control (cont.)

Heat, 3rd Stage (Y1,Y2,W) Dual Capacity Units

The hot water pump is de-energized which directs all heat to satisfy the thermostat. The 1st stage of resistance heat is energized 10 seconds after “W” input, and with continuous 3rd stage demand, the additional stages of resistance heat engage sequentially every 5 minutes.

Emergency Heat (W only)

The fan is started on high speed, and the ﬁ rst stage of resistance heat is energized 10 seconds after the "W" input. Continuing demand will engage the additional stages of resistance heat sequentially every 2 minutes.

Cooling Operation

In all cooling operations, the reversing valve directly tracks the “O” input. Thus, anytime the “O” input is present, the reversing valve will be energized.

Cool, 1st Stage (Y1,O)

The blower motor and hot water pump are started immediately, the loop pump(s) is energized 5 seconds after the “Y1” input is received. The compressor will be energized (on low capacity for Dual Capacity units) 10 seconds after the “Y1” input. The ECM blower will shift from low to medium speed 15 seconds after the “Y1” input (85% of medium speed if in dehumidiﬁ cation mode).

Cool, 2nd Stage (Y1, Y2, O) Single Speed Units

The fan changes to high speed (85% of high speed if in dehumidiﬁ cation mode) 15 seconds after the “Y2” input (ECM only).

Cool, 2nd Stage (Y1, Y2, O) Dual Capacity Units

The second stage compressor will be activated 5 seconds after receiving a “Y2” input as long as the minimum ﬁ rst stage compressor run time of 1 minute has expired. The ECM blower changes to high speed 15 seconds after the “Y2” input (85% of high speed if in dehumidiﬁ cation mode). The Comfort Alert will delay the second stage compressor until 5 seconds after it receives a “Y2” from the board.

Lockout Conditions

During lockout mode, the appropriate unit and thermostat lockout LEDs will illuminate. The compressor, loop pump, hot water pump, and accessory outputs are de-energized. Unless the lockout is caused by an ECM2 low RPM fault, the fan will continue to run on low speed. If the thermostat calls for heating, emergency heat operation will occur. Comfort Alert lockouts cannot be reset at the thermostat. All other lockout modes can be reset at the thermostat after turning the unit off, then on, which restores normal operation but keeps the unit lockout LED illuminated. Interruption of power to the unit will reset a lockout without a waiting period and clear all lockout LEDs.

High Pressure

This lockout mode occurs when the normally closed safety switch is opened momentarily (set at 600 PSI).

Low Pressure This lockout mode occurs when the normally closed low

pressure switch is opened for 30 continuous seconds (set at 40 PSI). A low pressure fault may also be indicated when a Comfort Alert lockout has occurred.

Freeze Sensing (Water Flow)

This lockout mode occurs when the freeze thermistor temperature is at or below the selected freeze sensing point (well 30°F or loop 15°F) for 30 continuous seconds.

Condensate Overﬂ ow This lockout mode occurs when the condensate overﬂ ow

level has been reached for 30 continuous seconds.

Fan RPM The control board monitors fan RPM to sense operation.

This lockout mode occurs if the fan RPM falls below the low RPM limit (100 RPM) for 30 continuous seconds (ICM only).

Fan (G only)

The fan starts on low speed (PSC ON). Regardless of fan input “G” from thermostat, the fan will remain on low speed for 30 seconds at the end of each heating, cooling or emergency heat cycle.

A DIP switch on the Envision control allows ﬁ eld selection of 15% reduced fan speeds for cooling in the dehumidiﬁ cation mode or medium and high fan speeds for cooling in the normal mode.

Note: Fan speed can change automatically only with an ECM Motor.

ECM2 Airﬂ ow Selection DIP Switches (SW1)

A 12-position DIP switch package on the Envision control allows the airﬂ ow levels to be set for low, medium and high speed. (Refer to the ECM Blower Table on page 15.)

Only three of the DIP switches can be in the “on” position. The ﬁ rst “on” switch (the lowest position number) determines the “low speed fan” setting. The second “on” switch determines the “medium speed fan” setting, and the third “on” switch determines the “high speed fan” setting, (see page 15).

ENVISION RESIDENTIAL INSTALLATION MANUAL

Microprocessor Control (cont.)

Compressor Monitoring/Comfort Alert

The comfort Alert displays abnormal compressor conditions through a unique ﬂ ash code and communicates the conditions to the heat pump microprocessor control. The heat pump microprocessor will determine which fault to act on and ignore. Fault codes 2 (system pressure), 4 (locked rotor), 6 (open start circuit), and 7 (open run circuit) will result in a lockout. All other fault codes are passive. All compressor alerts are displayed on the module by ﬂ ashing the yellow Alert LED a speciﬁ c number of times consecutively followed by a pause, and then repeated. The number of consecutive ﬂ ashes or “Flash Code” correlates to a speciﬁ c abnormal condition. The red “TRIP” LED means there is a thermostat demand signal “Y” present but the compressor is not running. The green “POWER” LED means the module has power.

Green "POWER" LED - module has power Red "TRIP" LED - Thermostat "Y" demand signal is present, but the compressor is not running.

Comfort Alert Flash Codes

1. Initiate a control signal to energize the blower motor. Check blower operation.

2. Initiate a control signal to place the unit in the cooling mode. Cooling setpoint must be set below room temperature.

3. First stage cooling will energize after a time delay.

4. Be sure that the compressor and water control valve or loop pump(s) are activated.

5. Verify that the water ﬂ ow rate is correct by measuring the pressure drop through the heat exchanger using the P/T plugs and comparing to unit capacity data in speciﬁ cation cata lo g .

6. Check the temperature of both the supply and discharge water (see pages 35-36).

7. Check for an air temperature drop of 15°F to 25°F across the air coil, depending on the fan speed and entering water temperature.

8. Decrease the cooling set point several degrees and verify high-speed blower operation.

9. Adjust the cooling setpoint above the room temperature and verify that the compressor and water valve or loop pumps deactivate.

10. Initiate a control signal to place the unit in the heating mode. Heating set point must be set above room temperature.

11. First stage heating will energize after a time delay.

12. Check the temperature of both the supply and discharge water (see pages 35-36).

13. Check for an air temperature rise of 20°F to 35°F across the air coil, depending on the fan speed and entering water temperature.

14. If auxiliary electric heaters are installed, increase the heating setpoint until the electric heat banks are sequenced on. All stages of the auxiliary heater should be sequenced on when the thermostat is in the Emergency Heat mode. Check amperage of each element.

15. Adjust the heating setpoint below room temperature and verify that the compressor and water valve or loop pumps deactivate.

16. During all testing, check for excessive vibration, noise or water leaks. Correct or repair as required.

17. Set system to desired normal operating mode and set temperature to maintain desired comfort level.

18. Instruct the owner/operator in the proper operation of the thermostat and system maintenance.

Note: Be certain to ﬁ ll out and forward all warranty registration papers.

Troubleshooting

Standard Microprocessor Controls

To check the unit control board for proper operation:

1) Disconnect thermostat wires at the control board.

2) Jumper the desired test input (Y1, Y2, W, O or G) to the R terminal to simulate a thermostat signal.

3) If control functions properly:

• Check for thermostat and ﬁ eld control wiring (use the diagnostic inputs mode).

4) If control responds improperly:

• Ensure that component being controlled is functioning (compressor, blower, reversing valve, etc.).

• Ensure that wiring from control to the component is functioning (refer to the LED Deﬁ nition table below and use the diagnostic outputs mode).

• If steps above check properly, replace unit control.

Refrigerant Systems

To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Compare the change in temperature on the air side as well as the water side to the tables on pages 35-36. If the unit’s performance is not within the ranges listed, and the airﬂ ow and water ﬂ ow are known to be correct, gauges should then be installed and super- heat and subcooling numbers calculated. If superheat and subcooling are outside recommended ranges, an adjustment to the refrigerant charge may be necessary.

Note:

Refrigerant tests must be made with desuperheater turned “OFF”.

Verify that air and water ﬂ ow rates are at proper

levels before servicing the refrigerant circuit.

ENVISION RESIDENTIAL INSTALLATION MANUAL

Preventive Maintenance

Water Coil Maintenance

1. Keep all air out of the water. An open loop system should be checked to ensure that the well head is not allowing air to inﬁ ltrate the water line. Lines should always be airtight.

2. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the discharge line to prevent loss of pressure during off cycles. Closed loop systems must have positive static pressure.

Note: On open loop systems, if the installation is in an area with a known high mineral content (125 PPM or greater) in the water, it is best to establish with the owner a periodic maintenance schedule so the coil can be checked regularly. Should periodic coil cleaning be necessary, use standard coil cleaning procedures which are compatible with either the cupronickel or copper water lines. Generally, the more water ﬂ owing through the unit the less chance for scaling.

Other Maintenance

Filters

Filters must be clean to obtain maximum performance. They should be inspected monthly under normal operating condi-

tions and be replaced when necessary. Units should never be operated without a ﬁ lter.

Condensate Drain

In areas where airborne bacteria produce a slime in the drain pan, it may be necessary to treat chemically to minimize the problem. The condensate drain can pick up lint and dirt, especially with dirty ﬁ lters. Inspect twice a year to avoid the possibility of overﬂ ow.

Blower Motors

ECM blower motors are equipped with sealed ball bearings and require no periodic oiling.

PSC blower motors should only be lubricated if dry operation is suspected.

Desuperheater Coil

See Water Coil Maintenance section above.

Air Coil

The air coil must be cleaned to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or vacuum (with a brush attachment) clean. Care must be taken not to damage the aluminum ﬁ ns while cleaning.

CAUTION: Fin edges are sharp.
