    Replacing Selco thermostat
    On my old Selco thermostat, I have the following wires:

    W2 - White
    O - Orange
    X - Blue
    R - Red
    G - Green
    Y - Yellow

    My new thermostat has the following terminals:

    G
    RC (jumper to RH)
    RH (jumper to RC)
    Y/O
    W/B
    Y1

    I believe that R (Red) will connect to RH, G (Green) will connect to G, Y (Yellow) will connect to Y/O, X (Blue) is common and not needed. I'm not sure about the Orange and White wires though. Can anyone help me out with this one please?
