    Wiring Honeywell RTH230
    Hello,

    I bought a Honeywell Thermostat for my heating and air conditioning. The model is RTH230B. I have 5 wires- the colors are red, white, yellow, green, and blue. The connector areas are listed as Rh, Rc, W, Y, G. I am having trouble wiring this thermostat so that I get cool air. In the winter, I was able to get heat but when I went to turn my A/C on today it would not work. How should the wiring be hooked up? I would appreciate any help with this!

    Did you add the jumper wire from RC to RH on the thermostat? If not you will need it.
