Since residential thermostats are designed 24 volt ac you would need to use one that has alternate battery power as DrewE said. Motorhome thermostats are designed for 12 volt dc operation. I have 2 heat pumps and 2 furnaces so in my case, I would need 2 thermostats, one for each a/c furnace combination. Also most newer motorhomes use remote sensors and home thermostats typically sense at the thermostat, making location difficult.
To answer Doug's question. Modern home thermostats have a 3rd selection "AUTO" for auto change over from heat to cool with a built in differential between the heat and cool setting of no less than 2 degrees differance. If heat is set to 70, cool can't be set lower than 72. Referred to as the thermostats "dead zone".
