Heat Mode in Cool with Electric Heat Units

When the t-stat is in the Heat Mode, if the indoor ambient temperature is below the heat set point, the fan turns on 5 seconds prior then the electric heat will turn on. When the t-stat is satisfied, the electric heat will turn off. The fan turns off 15 seconds later.

Heat Pump With Electric Heat Operation

This heating has two heating methods. If the ambient indoor temperature is below the heat set point and the compressor is not locked out, the compressor turns on. If the ambient temperature rises above the t-stat’s heat set point, the compressor turns off.

If the Compressor is Locked Out on the 3 Minute Time Delay and Electric Heat is Available

1.The control turns on the electric heat until the compressor is not locked out.

2.After lockout, the control turns off the electric heat, waits 5 seconds, then turns on the compressor. (The wired remote wall t-stat’s time delay may override this feature).

Condition 1

Thereafter, the unit will switch back to Heat Pump heat until the outdoor coil temperature sensor rises to 45 or greater.
