Test Operation
• Turn on the power to the Heat Pump.
• On the thermostat, slide the Mode Switch to HEAT. Press the COOLER
or WARMER button until the set temperature is 10 degrees above room
temperature. The HVAC unit should energize in the heating mode.
Note: You may need to wait up to five minutes for heating to energize
due to the compressor lockout feature. There is a two minute minimum
run-time for first stage heating.
• On the thermostat, slide the Aux Heat Switch to the NORMAL position.
The Aux Heat icon will appear indicating that the thermostat has
energized Aux Heat (page 7).
• TWO STAGE OPERATION - The 2nd stage of heat (auxiliary heat) is
turned on when the room temperature is equal to or less than: the
setpoint minus the 1st stage deadband (one degree, non-adjustable),
minus the 2nd stage deadband (two degrees, non-adjustable).
