New Thermostat not functioning
I recently "upgraded" to a digital thermostat so I could program heat cycles while out of the house. The HVAC unit is an Intertherm sealed cumbustible furnace model number MGHA-056ABFC-01 that runs on propane. The entire unit sits in the house and it has two wires going to the thermostat (red and white). The digital thermostat I installed is a Honeywell RTH230B, 5-2 programmable. When I installed the new thermostat I connected the red wire from the fan to the Rh terminal on the thermostat and the white heating wire to the W terminal.
The problem is that I can turn the heat on and off at the thermostat but it will stay on constantly. It won't cycle to the temperature I set.
Any suggestions?
