Progammable Thermostat Common Wire
I am installing a new programmable thermostat (Hunter 44860) but would like to have it use the household electricity and not just run off of the batteries. My current thermostat is a 3 wire setup (Y-RC-W, with jumper from RC to RH). I plan on running another wire to connect the common leg to C on the thermostat, but where does it connect to? Currently the RC wire is connected to a 24V transformer off in the basement. Thanks in advance for any help.
