I installed a programmable thermostat this Fall for my heatpump. I more or less accepted the default schedule as it fit my daily schedule fine. I notice the aux heat (resistance coils) kick in a lot when the heatpump first comes on. I assume this is due to the temperature differential between the initial warming air the heatpump creates and how cool it is in the house. I see no way to control this in the thermostat. Somehow the thermostat is making a calculation and determining when to kick in the aux heat. I'd like to lower this threshold if possible to keep it from kicking in as often. It almost seems to do it every time it comes on.
