You must use a battery powered thermostat- if it needs power through the RC or RH connections, it will not work with the DuoTherm. The furnace does not hook to the thermostat- it is connected to the air conditioner.
Thanks for the help chris.....the thermostat is battery powered i changed the batteries yesterday to make sure they were good.....the rep from lux corp had me touching wires together to check for power and nothing was working.....he said they usually check the fan motor because that is independent....
