Wiring Thermostat 2441TH

Hello,

I am trying to wire/install this thermostat. I know where most (w,g,y,rh) of the wiring connect except. My old thermostat has a "RC" wire. Where do I connect that one?

Please see picture.

Thank you.

Maybe this post on the Insteon forum will help? Otherwise, I'd just contact Smarthome and see if they can help.

Re: Wiring Thermostat 2441TH

What kind of system is that old thermostat controlling? Heat Pump? AC + Furnace?

The R wires are power for the thermostat. Some systems have two because there are two different systems that might be controlled from one thermostat.

In most cases, connecting the Red RC wire to the R terminal of the thermostat is all you need to do, as long as the air handler is part of the AC unit and is always on.
