I am thinking that my aux heat is kicking in too much. I thought perhaps a newer thermostat with an outdoor sensor might help a bit.
I have a heat pump with back up electric heat in the air handler. Due to spouse illness, I want a thermostat that keeps as steady heat as possible, plus or minus 1. I would like a thermostat that is lit all the time, not just when I hit a button.
Any ideas of what I should look at? Thanks.
