I have a thermostat question...hoping someone can help.
I currently have a approx 2900 finished sqft house, have a natural gas forced air furnace and electric central A/C system. Have a thermostat, older but digital, on the first floor. Wires includes Y,G,W, and Rh, no C wire. Works fine.
However, we are also installing a Quadrafire pellet stove for primary heat during the winter. The furnace will (hopefully) be used only as a backup if pellets run out during the night or during very cold nights.
I have a simple thermostat which is programmable which we purchased compatible with the stove. I am told that the stove requires a 12 volt thermostat with cold contact closure. This requires "2 wire" thermostat wire.
I would like to move/install a new thermostat. Ideally, I could find one thermostat that could control the central air, gas heat and pellet stove. I forsee somewhat of a two-stage system where the pellet stove is primary and the heater only kicks on if the house fails to heat appropriately with the pellets.
I would LOVE the Nest thermostat. This is a 24 volt thermostat however, and I'm told perhaps this is not compatible with the 12 volt required by the pellet stove.
Is there a way to combine all 3 devices on a single, integrated thermostat? Maybe a different one, not a Nest? Or would the Nest work? I could also install thermostats but would like to avoid this if possible. Using the Nest for my A/C and forced air is less than ideal since I intend to use the forced air heat minimally, using the pellet stove primarily during the winter, which kind of defeats the point of the Nest.
