    Thermostat Wiring
    I am having similar thermostat problem as krich22774 had on 4/16. I installed the Honeywell RTH230B thermostat during the winter and the heat worked fine. Now when I turn on the A/C nothing happens.

    I have 5 wires coming from the wall. I started with the following setup:

    Rh-Red
    Rc-Blue
    W-W
    Y-Y
    G-G

    After switching to the following I got A/C working correctly, but no heat.

    Rh-Blue
    Rc-Red
    W-W
    Y-Y
    G-G

    After switching to the following both A/C and Furnace turned on.

    Rh-Blue
    Rc-Jumper
    W-W
    Y-Y
    G-G

    After switching to the following I got nothing to work.

    Rh-Blue
    Rc-Jumper
    W-W
    Y-nothing
    G-G

    I have a Bryant 350AAV furnace and a Bryant 561CJ030-E outside A/C unit. Any help or suggestions would be greatly appreciated. Thanks.

    Jumper needs to be between RH and RC and hook your red wire to one of the two
