OPERATION

Unit Heat Control Operation - HeatPump With Electric Heat

If the ambient indoor temperature is below the heat demand threshold (1.5˚F below the heat set point temperature), and the

compressor is not locked out, turn on compressor. If the ambient indoor temperature is .25˚F above the heat set point turn off the

compressor..

Figure 348 (Heat Control (Heat Pump & Electric Heat)

If the compressor is locked out & electric heat is available:

1. Turn on the electric heat until the compressor is not locked out.

2. After lockout, turn off the electric heat, wait 5 seconds, then turn on the compressor.

If Electric Heat is Available:After the Heat button is initially pressed, the unit will run the electric heater rst until the initial set point is satised

(Hot Start Feature). After the initial start, the unit will switch to Heat Pump heat and decide between Heat Pump heat and Electric heat based on the

following two monitored conditions:

Condition 1

If the outdoor coil temperature sensor drops to 30 ˚F or less for 2 consecutive minutes, the unit will switch to electric heat if available. Thereafter, the

unit will switch back to Heat Pump heat if the outdoor coil temperature sensor rises to 45 ˚F or greater.

If Electric Heat is not available (out of order) and the outdoor coil temperature sensor drops to 30 ˚F or less for 2 consecutive minutes, then the

compressor and fan will turn off. Thereafter, the unit will switch back to Heat Pump heat if the outdoor coil temperature rises to 45 ˚F or greater.

Condition 2

If the delta (set point temperature minus the ambient indoor temperature) is greater than 5 ˚F, then the unit will switch to electric heat, if available.

The unit will continue to operate with electric heat until the heat demand is satised. Note that the electric heat switches on after the delta temp

passes 5°F and the heat pump switches off. Also note that the electric heat will run until the heat demand is satised. When another heat demand

cycle is initiated, the heat pump will run unless the delta temp is greater than the electric heat threshold.
