Litaelo tsa Tšebeliso ea Sehlahisoa
Mosebetsi o Nepahetseng oa Thepa:
Ensure the thermostat or zone board is connected to the
designated terminal strip, and the air handler or furnace is
connected to its respective terminal strip. Additional terminal
strips may be present based on the model type.
Heating and Cooling Functions:
- A Y call initiates heating or cooling. After 20 minutes, AUX
heat will activate if needed. AUX heat remains on until the
thermostat is fully satisfied. - In cooling mode, the O signal triggers the reversing valve and
e thibela tlhahiso ea mocheso oa aux. - To save energy, the PLC cuts power to the crank case heater
when the compressor runs.
WG2AH Forced Air with Hydronic Heating Function:
In addition to WG2A features, WG2AH units offer switching
priority from forced air to hydronic heating and Split Zone
tshebetso.
Switching Priority:
Use a jumper on the field wiring terminal strip between R and AW
to prioritize air heating over hydronic heating. Removing the
jumper makes hydronic heating the priority call.
Split Zone Feature:
Split Zone lets you heat one zone with hydronic heat and another
with forced air. Activate Split Zone by moving the jumper from R
and AW to R and SZ on the field wiring terminal block.
Lipotso tse atisang ho botsoa (FAQ)
Q: Can I use any thermostat with the Smart Logic
Molaoli?
A: Yes, the PLC program allows for the use of almost any
heat/cool thermostat, but Total Green Mfg. recommends using
Honeywell 8000 series thermostats for optimal performance.

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.

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.

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.

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.

2) 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.
3) 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.
4) 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.
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.
