    Wiring a Honeywell RTH3100C thermostate
    I currently have a Honeywell RTH7000 series programmable thermostat. It broke so I bought a Honeywell RTH3100C non-programmable. I want to get some help in wiring it beforehand because I had problems wiring up the 7000.

    Current wiring w/ wire colors:
    blue - C
    green - G
    yellow - Y
    orange - O/B (labeled this on terminal of thermostat)
    red - R
    white - auxiliary
    black - E
    brown - capped off

    The new thermostat has:
    E, Aux, Y, G, O, L, R, B, C terminals

    Is the following correct in translating the old wiring to new?
    C = C
    G = G
    Y = Y
    O/B = O
    R = R
    Aux. = Aux
    E = E
    Leave brown wire capped?

    Yep, the meaning of the terminal O/B probably needs to be set in the stat. If it's wrong, you'll get heat in cool mode and vice versa.
