I am using only 1 thermostat with my OWB, I currently have forced air/heat pump with a heat exchanger. I was told just use my current thermostat (to run the blower)and throw the breakers on the outdoor heat pump, so if the water temp get cool the aux. heat (indoor furnace) will kick on and provide heat untill the water temp rises. It seems to work fine other than a hum at the outdoor unit when the blower kicks on.
Let me know good, bad?
Thanks
