My Trane heat pump does a good job of heating my house without the use of electric strips. I do have the outdoor sensor that will disable the heat strips at temps above 40 degrees but even using intelligent recovery, my heat strips come on way too often. I set back my thermostat from 70 to 68 at night. Also, during the day I notice my heat strips are cycling on and off even with the temperature the same as the set point. My tech changed the CPH rate but the aux heat still comes on when it is not needed.
The tech said I could change setting 170 (SYSTEM TYPE) from 7 (2 HEAT/1 COOL HEATPUMP WITH AUX HEAT) to 2 (1 HEAT/1 COOL HEATPUMP NO AUX HEAT) and that would completely disable the heat strips. That sounds fine with me as I would rather be a little uncomfortable and save money as my electric bill is very high when the strips come on. My question is will changing that setting harm my heat pump? Any reason I shouldn't change it? Will that change indeed disable the heat strips?
When I do need the strips, I can always change it back right? Thank you very much for any help.
