    Existing wiring to a new thermostat
    Old thermostat has white,red, brown & green wires respectively, going to w,r,y,g connectors.

    The new thermostat has w,rh,b,rc,G,O,& Y connectors. (RC/RH ARE JUMPED TOGETHER.)

    My system is a standard heat/cool with attic air handler and outside compressor.

    What goes where on new thermostat? Any help is greatly appreciated.

    before you do anything turn off power to furnace/airhandler at breaker box
    white = w
    red = rh
    brown =y
    green =g
    leave jumper in if your system has only 1 transformer
