    Honeywell rth7500. Can't figure out wires
    I did a stupid. I took off the old non-progamable stat and didn't mark my wires.

    Here are the wires that I have. Red, yellow, blue, green, white and Orange. I'm not sure where they go.

    I have a Bryant furnace, heat pump and Air cond. This is a new house less than 6months old.

    Any help would be appreciated.

    Thank you

    More than likely, like this: Red to Rh, with jumper to Rc; White to W; Yellow to Y; Green to G; Blue to C; Orange to O; Check low-voltage connections at furnace-does blue wire connect to C terminal? If so, follow above instructions.
