• 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.

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.

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

WG2AH Aer forțat cu funcție de încălzire hidraulică

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. pompele de apă încep să stabilească un debit bun. 30 de secunde după aceeatage.g., compresorul pornește. Odată ce termostatul rezervorului este satisfăcut, compresorul se oprește și pompa va continua să funcționeze timp de 30 de secunde înainte de a se opri pentru a recupera căldura reziduală de la schimbătorul de căldură. La 1 minut după ce compresorul se oprește, supapa cu 3 căi se dezactivează. La 1 minut după aceea, compresorul poate reporni pentru o solicitare a zonei de aer. Aceste cicluri temporizate reduc uzura componentelor sistemului, nefiind necesară schimbarea sub presiune sau sarcină.
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.

WG2AD Aer forțat cu funcție de încălzire a apei menajere

Pe lângă funcțiile și caracteristicile descrise pentru unitățile WG2A, așa cum este descris în prima secțiune a acestui document, programul PLC pentru unitățile WG2AD permite comutarea apelului prioritar de la încălzirea cu aer forțat la încălzirea apei menajere.

• 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. pompele de apă încep să stabilească un debit bun. 30 de secunde după aceeatage.g., compresorul pornește. Odată ce termostatul rezervorului este satisfăcut, compresorul se oprește și pompa va continua să funcționeze timp de 30 de secunde înainte de a se opri pentru a recupera căldura reziduală de la schimbătorul de căldură. La 1 minut după ce compresorul se oprește, supapa cu 3 căi se dezactivează. La 1 minut după aceea, compresorul poate reporni pentru o solicitare a zonei de aer. Aceste cicluri temporizate reduc uzura componentelor sistemului, nefiind necesară schimbarea sub presiune sau sarcină.
• 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.

Comutatoarele de presiune și temperatură joasă HX sunt automate.
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.
