Auxiliary resistance heat is the expensive mode. Big thermostat setbacks trigger it on recovery, so a steady setting usually beats aggressive setbacks.
Cold-climate models hold useful capacity well below freezing; older units fall back to strips much sooner.
Keeping the outdoor coil clear of snow, leaves and shrubs protects the efficiency you paid for.
