    Honeywell rth230B thermostat installation
    I have an air handler in the ceiling of the garage and a condenser outside. I live in Fl and 95 in the house all the time is too hot.

    I am trying to install the Honeywell RTH230B thermostat. The old thermostat had the following wires

    Red: rc
    White: w
    Green: g
    Yellow: y
    Blue: c

    I have put
    Red: rh
    White w
    Yellow y
    Green g
    Blue nowhere

    I put batteries in. NOthing . The habdler is not running. The a.c is not running.

    I do not know what I did wrong.. Should I go buy an easier one? I am a single mother trying to self sufficient.

    Add a jumper wire from RC to RH(at the thermostat). It should get you up and going.

    Unfortunately it has a jumper and still does not work. All the circuit breakers are on. The handler and the air condenser.
    I have tried twice.

    Did you turn the power off going to the air handler first.(if not you may have blown a transformer or low voltage fuse) With the thermostat apart if you jump R to G or R to Y will any thing run? If not it's a voltage problem.
