• All Total Green Mfg. forced air units will have separate terminal strips labeled  “thermostat/zone board” and “air handler/furnace” for low voltage and are PLC  “controlled.
• For proper equipment function, the thermostat or zone board must be tied to the  “thermostat/zone board terminal” strip. The air handler or furnace must be tied to the “air handler/furnace” terminal strip. There will also be additional terminal strips  for various functions based on the model type you may be working with. The information provided here is to supplement the installation manual specific to your unit.
• IMPORTANT: For WGxA, WG2AH and WG2AD unit’s, if using a cased coil over a furnace, do NOT program your thermostat for dual fuel mode or, use the furnace settings. Leave the thermostat set to electric aux. heat, otherwise, you may interfere with proper PLC function. Follow the dual fuel function option for the unit model you are installing. This information is detailed in your unit installation manual. You will also want to check the aux. heat cycle rate (CPH) setting in the thermostat and set this to 1 or, the lowest available value depending on your thermostat brand and model.

WG1A Forced Air Only– List of functions

1. The PLC checks that the LOW/HIGH pressure and discharge temperature switches are made. An open pressure switch input has a 60 second delay before setting a lockout and fault signal to  “X”. This is to prevent nuisance calls, especially at the beginning of the cooling season when the Earth Loops are at their coldest. “X” is set with any hard lockout condition. Turning the low voltage si awọn konpireso kuro ki o si pada lori awọn atunto awọn lockout bi gun bi awọn yosita otutu yipada ni ko sisi. Yipada iwọn otutu itusilẹ ni bọtini atunto afọwọṣe.

2. A “Y” call starts heating or cooling. A 20-minute timer will bring on AUX heat should that time elapse without having satisfied the heating call. Once aux. heat is called, aux. heat will stay called until the thermostat fully satisfies.
3. There is an installed jumper on the field wiring terminal block marked “A” and “S”. With the jumper installed, the unit will function with an aux heat strip as normal. If the jumper is removed, the PLC goes into dual fuel mode stopping the compressor when there is a call for aux heat. Once the aux heat call completes, a 5-minute cool down timer prevents the compressor from restarting on a “Y” call until the time elapses. This allows time for the furnace to cool so hot air doesn’t cause high discharge pressure or a lockout when the compressor restarts.
4. When the thermostat is set to cooling mode, the “O” signal energizes the reversing valve and locks out the aux heat output.
5. In an effort the reduce energy consumption, the PLC turns power off to the crank case heater when the compressor runs.
6. This PLC program also allows the use of almost any heat/cool thermostat. Total Green Mfg. Strongly recommends using Honeywell 8000 series thermostats.
7. If either the compressor unit or, the air handler/cased coil sensor detects a refrigerant leak, the unit will go into lockout mode disabling the compressor and backup heat source. The blower on forced air units will be activated and, the “LA” (Leak Alert) light along with the “X” (Lock Out) will turn on along with the “LA” terminal being energized with 24 volts AC. This terminal can be used as a trigger, if required by your local building codes, to set off a remote alarm and/or trigger a mechanical room exhaust fan in the event of a refrigerant leak.

WG2A Forced Air Only– List of functions

1. The PLC checks that the LOW/HIGH pressure and discharge temperature switches are made. An open pressure switch input has a 60 second delay before setting a lockout and fault signal to“X”. During this 60 second time period, the compressor will only operate in 1st stage giving the system a chance to recover before setting a hard lock out. This is to prevent nuisance calls, especially at the beginning of the cooling season when the Earth Loops are at their coldest. “X” is set with any hard lockout condition.

If the system is air zoned, a Zone Override terminal “D” will energize to 24 volts. As described in your unit installation manual, this 24-volt signal can be used along with a field supplied isolation relay to call open the  largest zone and hold that damper open so the blower doesn’t see high static pressure during those 5 minutes. The maintenance cycle locks any other call out until completion. After the maintenance cycle, or if a “Y2” call is made before the maintenance cycle occurs, the
4.  counter resets back to zero. This makes our system zone friendly as it allows for true 2 stages alapapo ati itutu.
   There is an installed jumper on the field wiring terminal block marked “A” and “S”. With the jumper installed, the unit will function with an aux heat strip as normal. If the jumper is removed, the PLC goes into dual fuel mode stopping the compressor when there is a
   call for aux heat. Once the aux heat call completes, a 5-minute cool down timer prevents the compressor from restarting on a “Y” call until the time elapses. This allows time for the furnace to cool so hot air doesn’t cause high discharge pressure or a lockout when the compressor restarts.
5.  When the thermostat is set to cooling mode, the “O” signal energizes the reversing valve and locks out the aux heat output.

8. If either the compressor unit or, the air handler/cased coil sensor detects a refrigerant leak, the unit will go into lockout mode disabling the compressor and backup heat source. The blower on forced air units will be activated and, the “LA” (Leak Alert) light along with the “X” (Lock Out) will turn on along with the “LA” terminal being energized with 24 volts AC. This terminal can be used as a trigger, if required by your local building codes, to set off a remote alarm and/or trigger a mechanical room exhaust fan in the event of a refrigerant leak.

WG2AH Forced Air with Hydronic Heating Function

In addition to the function and features as described for WG2A units, The PLC program for the WG2AH units allows for switching priority call from forced air to hydronic heating as well as a  feature called “Split Zone” that are installer optioned by choosing jumper settings as described  below.

1. A jumper is used on the field wiring terminal strip between the “R” and “AW” terminals to prioritize air heating over hydronic heating. When this jumper is removed, hydronic heating becomes the priority call.
2. Split Zone is a feature which allows you the ability to heat one zone or floor with hydronic heat and another zone or floor with forced air. Split Zone is active by removing the priority call jumper across “R” and “AW” moving it across the “R” and “SZ” of the field wiring terminal block.
3. While in “Split Zone” mode, the compressor unit will provided forced air heating to the air zone. When the buffer storage tank calls for heat, the compressor unit will shift to heat water. Should a call for the air zone take place while the compressor unit is heating water, the call goes directly to the aux heat source to maintain the air zone. Once the tank temperature is satisfied, the system diverts back to normal air heating with the compressor unit.
   1. When a hydronic heat call from the buffer tank takes place, the compressor turns off if it is running. 1 minute after that, the 3 way valve energizes and the SV1 valve de-energizes. 30 seconds after that stage, the water pumps starts to establish good water flow. 30 seconds after that stage, the compressor starts. Once the tank thermostat is satisfied, the compressor stops and the pump will continue to run for 30 seconds before turning off to gain any residual heat from the heat exchanger. 1 minute after the compressor stops, the 3-way valve de-energizes. 1 minute after that the compressor can restart for an air zone call. These timed cycles reduce system component wear by not having to shift under pressure or load.
4. The Hydronic heating function is disabled anytime the “O’ terminal is energized placing the unit in cooling mode.
5. If either the compressor unit or, the air handler/cased coil sensor detects a refrigerant leak, the unit will go into lockout mode disabling the compressor and backup heat source. The blower on forced air units will be activated and, the “LA” (Leak Alert) light along with the “X” (Lock Out) will turn on along with the “LA” terminal being energized with 24 volts AC. This terminal can be used as a trigger, if required by your local building codes, to set off a remote alarm and/or trigger a mechanical room exhaust fan in the event of a refrigerant leak.

• A jumper is used on the field wiring terminal strip between the “R” and “AW” terminals to prioritize air heating/cooling over domestic water heating. When this jumper is removed, domestic water heating becomes the priority call.
• When a water heating call from the water tank takes place, the compressor turns off if it is running. 1 minute after that, the 3 way valve energizes and the SV1 valve de-energizes. 30 seconds after that stage, the water pumps starts to establish good water flow. 30 seconds after that stage, the compressor starts. Once the tank thermostat is satisfied, the compressor stops and the pump will continue to run for 30 seconds before turning off to gain any residual heat from the heat exchanger. 1 minute after the compressor stops, the 3-way valve de-energizes. 1 minute after that the compressor can restart for an air zone call. These timed cycles reduce system component wear by not having to shift under pressure or load.
• An added functional PLC feature exclusive to the WG2AD model which allows water heating up 120 degrees, is the unit’s ability to maintain compressor stability by throttling the compressor load as needed to control discharge pressure.
• If either the compressor unit or, the air handler/cased coil sensor detects a refrigerant leak, the unit will go into lockout mode disabling the compressor and backup heat source. The blower on forced air units will be activated and, the “LA” (Leak Alert) light along with the “X” (Lock Out) will turn on along with the “LA” terminal being energized with 24 volts AC. This terminal can be used as a trigger, if required by your local building codes, to set off a remote alarm and/or trigger a mechanical room exhaust fan in the event of a  refrigerant leak.

WG1H 100% Hydronic Heated and Chilled Water Only– List of functions

1. The PLC checks that the LOW/HIGH pressure, HX Low and Discharge temperature switches are made. An open safety switch input has a 60 second delay before setting a lockout and fault signal to “X”. This is to prevent nuisance calls, especially at the beginning of the cooling season when the Earth Loops are at their coldest. “X” is set with any hard lockout condition.

2. An “N” call starts the circulator pump for 30 seconds prior to the compressor to allow for full flow through the HX (heat exchanger) prior to starting the compressor. Once the call is complete, the pump will run an addition 30 seconds after the compressor stops to purge the HX of any residual heat. This occurs regardless of either a heated or chilled water call.
3. If the compressor unit sensor detects a refrigerant leak, the unit will go into lockout mode disabling the compressor. The “LA” (Leak Alert) light along with the “X” (Lock Out) will turn on along with the “LA” terminal being energized with 24 volts AC. This terminal can be used as a trigger, if required by your local building codes, to set off a remote alarm and/or trigger a mechanical room exhaust fan in the event of a refrigerant leak.
