Allow the outdoor or indoor temperature sensor to absorb the air for a minimum of fi ve
minutes before taking a reading. See Service Menu 370, which controls Economizer/
Outside air damper behavior. Table 6 shows the Economizer/TOD behaviors of available
settings (Options include 0-4; 0 = OFF, which disables the Economizer function).

note: heat Pump compressor lockouts (shown below) are only available if an
outdoor temperature sensor is applied and confi gured (see table 1).
The options available in Service Menu 140 (below) are dependent on the selected System
Type, Service Menu 110.
DUal FUel heat PUmP anD remote oUtDoor remote sensor
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.

note: there is a minimum 5°F deadband between compressor and auxiliary heat
lockout temperatures.
Operation
When the outdoor temperature is:
• Below the Heat Pump Compressor Lockout Temperature, only the Auxiliary Heat
operates.
• Above the Heat Pump Auxiliary Lockout Temperature, only the Compressor
operates.
• Between the two temperatures, both the Compressor and Auxiliary Heat operate.
