I live in a townhome with a 2 stage system - a heat pump outside and then my recycler inside with the coils. I have an old manual thermostat to use and I wanted to upgrade to a digital thermostat. So how do I know what type of thermostat to get? Is there one specifically for a 2 stage systeam. My thermostat now is a White-Rodgers and the inside says : 2 stage Heat / 1 Cool, HTG. 1.0 Amps Max, CLG. 1.5 amps Max, Max. 30 volsts A.C. , Type 1F58W-58. thanks for the help!
