I have a Goodman 3 Ton Heat Pump with backup electric heat and my thermostat is a Honeywell TH6000. The problem is the electric AUX heat kicks on every time I go over 2 degrees, which can be confusing since the thermostat will show 70 when it's really 69.x - which to the thermostat means 2 degrees from "70" is actually 71.

I tried to reduce the CPH for auxiliary heat, but that didn't do anything. I finally set my thermostat mode to 1 Cool/1 Heat (Heat Pump w/o AUX).

Is there a way to change the temperature swings for AUX heat?

Or is it best energy-wise to let it use electric heat if I want to climb more than 2 degrees?
