Hey everyone, i have a split system air and electric furnace with a 2 wire thermostat. I would like to be able to use only 1 thermostat to be able to control my OWB, air, and my electric furnace as back up so the electric furnace will come on if in case something happens and the OWB can't make the temp. Like if i may be away from home for a few days. Can i use a 2-stage heat and a 1 stage air like the honeywell RTH7500D for this kind of hook-up? http://www.honeywellcentral.com/product/0-85267-25724-4.html I realize that i will have to run new thermostat wire or will i have to use 2 seperate thermostats? Any ideals on this set-up or any suggestions?
THANKS, Rodney
