I currently have a digital programmable thermostat in our house that is connected only to our radiant heat system and I just bought an Insteon thermostat to replace the old one with. The current thermostat has only two wires that appear to connect to 'W' and 'RH' and then there is a short jumper wire connecting 'RH' and 'RC'. Can anyone tell me if there are any problems in connecting the Insteon thermostat to a 2-wire system and whether I also need to connect a jumper in the new Insteon thermostat in the same way that the old thermostat is?
​Thanks!
