Jason,

Thanks for the detailed response! I definitely would want the t2000 hardwired then for power. So I will look for another wire but I think I might be back to hiring someone to do this as I’m guessing a wire will needed to be pulled for the C connection.

So I trying to get my head wrapped around this and I really have no experience with it other then doing wiring for IT related things. One thing I should note is that I have been using HVAC generically. I really only have the Heat part. I have no AC.

I’ve attached a few pics from the furnace side along with the pic of the wiring for the thermostat. What I’ve noticed on the furnace side is it appears that only the yellow wire (heat relay) and the green wire (Voltage) are attached. If you look a little below in the pic you can see the black and red wiring wrapped around the wire casing.

Does any of this make sense?

I have a service guy coming today. I’ll let everyone know the outcome. Thanks for the help so far!

It would depend on the HVAC. Some older tstat cables may only be two conductors to run a furnace, yes. In your case it looks like there are four but only two may be used. To alleviate any questions regarding the Furnace itself and how it is currently wired, the HVAC specialist will be best able to assist.

In this case if the other conductors are indeed unused you may be able to just use one as the C-wire.

So this is all set. The HVAC tech was here and reused one of the existing wires that was not attached to anything as the common wire.

I’m getting a low battery warning so I’m guessing I mis understood Jason’s post. I get it now. He meant do not run just batteries. I took it as don’t run batteries at all even though it’s connected to low voltage. I’ll put the batteries in now :slight_smile:

Thanks again for all the help!

Hey good news! And yes, I meant use both battery and AC. The Tstat must be learned into the panel while on AC power in order to function as a repeater
