Thermostat needed for OWB

[WMcroyal]

am new to this site so excuse me if this has been asked in the past. I have a 90 + Comfortmaker furnace that burns very expensive propane. I have 4 wires going to my existing stat that operates the furnace in heat and cool mode. My question is can I just hook up a 2 stage heat 2 stage cool thermostat and program it to run just the blower based on temp and not start the burners.

yes you may install a 2-stat stat. The w1 one the stat would go to the fan relay on furnace, and the w2 on stat would go to heat relay on furnace....Good luck, should work just fine!
