Hi:
I bought a 2 wire, heating only, millivolt thermostat to replace a non digital 2 wire thermostat.

The thermostat wires from the stove are connected to "RH" and "TH/TP" . The terminals in the new thermostat are labeled "RH" and "W".

"TH" wire from the stove would be connected to what terminal in the Thermostat... RH or W?

Thanks,

Ron
