    Trane Heat Pump tstat replacement with Honeywell prog - wiring question
    I want to replace my Trane Weathertron tstat with a Honeywell RTH7400 prog one. I have a Trane heat pump with aux heat. I've been poring over these thread piece-mealing some info the follow is the result.

    The old wiring scheme:
    X2 - black
    O - orange
    G - green
    Y - yellow
    T - tan/brown
    R - red
    W - white
    U - n/a
    F - n/a
    B - Blue

    The honeywell has the following options along with my current wiring in () as see on this forum.
    C - (blue)
    G - (green)
    Y - (yellow)
    O/B - (orange)
    RC - jumper with R
    R - red
    AUX - white
    E - tan
    L - black

    Results:
    Power runs to the tstat and fan blows on command in manual temp mode but the heat doesn't seem to be produced.

    Can anyone cofirm the correct wiring above ?

    Thanks in advance,
