    We have this new model, and one white white wire and one blue. Where do we plug them in? According to the diagram there are rh rc w on right and on left there are why and g. in the are and rc was already hooked with somewith right out of the package. We are at a loss, as soon as we wire it any of the many ways we have tried the ij just comes on and the heat pours and keeps going past where we set it. It gets all the way up to 80 until we just unhook everything/ I hope I am making sense/

    If you only have two wires to attach your system is for heat only since you have no A/C to hook up. Usually the wires go to the RH or just plain R and W terminals on the thermostat.

    Follow the instructions provided and follow the setup directions. You will need to know the type of furnace (gas,electric.oil. etc.) You also have to set the fan settings and time of day etc. naturally you should install the batterys properly before you start the program process.

    Copy of install manual.
