The fan for the bedroom heat is not coming on and I've narrowed it down  to the thermostat being the problem.  

The fan works just fine when I jump the 12v+ wire to the heat output on the back of the thermostat, so for whatever reason the original thermostat is not sending the needed voltage to the heater fan.

Since the thermostat controls both compressors on the AC and the heat I'm not sure what I can replace it with.  

Has anyone replaced the original PSG thermostat with another model that will work with our AC and the heat?

Thanks

Check the relays on the aquahot. Mine were bad so I changed them both and everything worked again.
