    Installing Honeywell RTH7400
    I am replacing my old thermostat with a new Honeywell RTH7400. Here are the wire terminals from my old one:
    G
    Y
    T
    R
    O
    W
    B
    X2

    and the terminals on the new one are:
    C
    G
    Y
    O/B
    Rc
    R
    Aux
    E
    L

    I have all the wires in except for the one off the old off the old thermostat that was connected to the "T" terminal. I have looked through the manual but I can't find this in there. Can someone tell me where to connect this? It would be very much appreciated!

    P.S. I for some reason can't access the honeywell site, it says I need to disable my cookies, but when I do it still won't let me, so links to there won't work.

    Thanks in advance!

    The "T" is a outdoor thermister, tape it off and don't connect it to anything, Good luck, Mike
