The options available in Service Menu 140 (below) are dependent on the selected
System Type, Service Menu 110.
In this operation, there is no external fossil fuel kit (dual fuel kit) installed; the thermostat
controls this function:
1. Choose the correct heat pump application in Service Menu 110, System Type.
2. Choose Outdoor Temperature Sensor (Options 3 or 5) for Control Option in Service
Menu 170, Remote Sensor.
3. Go to Service Menu 140, Auxiliary Heat, and choose “1.”
4. Choose an appropriate temperature balance point in Service Menu 180, Heat Pump
Compressor Lockout.
Operation in Heat Mode Above Balance Point (Outdoor Temperature)
When the outdoor temperature is above the selected balance point temperature (Service
Menu 180), only the compressor operates and the fan (G Terminal) energizes when the
thermostat calls for heat.
Operation in Heat Mode Below Balance Point (Outdoor Temperature)
When the outdoor temperature is below the selected balance point temperature (Service
Menu 180), only the Fossil Fuel (auxiliary heat) operates and the fan (G Terminal) does not
energize when the thermostat calls for heat.
If Service Menu 140 is set to “1” (fossil fuel Auxiliary Heat), the lockout control is as
follows:
