I have a natural gas fireplace with a standing pilot and a thermocouple in series with a normal SPST 120 volt switch. The switch is definitely connected only to the thermocouple circuit and not to any 120V source. From what I can determine, closing the switch allows current to flow to open a gas valve and the pilot ignites the gas. I want to be able able to use an electronic setback thermostat to ignite and turn off the gas burner at given times. It seems to me that I should just be able to take the the wires that are currently attached to the SPST switch and attach them to the RH and W terminals of an extra setback thermostat I have. When the thermostat calls for heat it will close the circuit and ignite the burner. When the set point has been reached, it will open the circuit and cut off the gas. In other words, it will function just as the SPST switch, but I will be able to control it by time and temperature. Does anyone have an opinion on this ideas?
