We are having a new single stage Furnace installed downstairs and we'd like to have them use the same Thermostat that we have upstairs on our 2-Stage furnace. It's a Honeywell FocusPro has a really HUGE display. My Dad is very old and already knows how to use it. I think it would save confusion for him if we could use the same Thermostat in both locations.
Can a 2-Stage Thermostat be used on a single stage furnace? Any advice greatly appreciated.
