    Trane Dual Fuel with fossil fuel kit to VP IAQ stat with outdoor sensor
    I would like to get rid of my TAYPLUS103A which is malfunctioning. I recently purchased a new VP IAQ with outdoor sensor for HP lockout. I am a little confused on wiring.

    My HP has the following connections:
    T (not used)
    O
    X2
    Y
    R
    B

    My furnace control board has the following connections:
    G
    W
    R
    C
    Y

    Questions:

    Do I wire both the HP Y connection and Furnace Y connection to the VP Y connection?
    Do I wire both the HP X2 connection and Furnace W connection to the VP AUX connection?

    All the other connections and stat programming make sense. Thanks for your help!
