I'm trying to install a new digital non programmable honeywell thermostat but, my old thermostat is a TRANE and has a wire lableled T and I don't know where to attaché it to the new thermostat.. Please help.
PS I have a heat pump.

I just did something like that a couple months ago... what I did was go to the 'new' thermostat company's web site and downloaded a picture that showed where all the wires (from the old one) attached to the new one

Hope this helps

You won't need it for the new thermostat, it was used for a trouble indicator light. Tape it off and move forward.
