Connect the 24-volt power wire to RH. Leave the jumper connecting RH to RC (in some thermostats, this option will be a wire jumper across the terminal connections, while in other thermostats this will be a RH-RC shorting cap on the circuit board). Connect the heat wire to W1, and the cooling wire to Y or Y1.
How do I wire my thermostat for a 3-wire heating and cooling system (with one wire for heat, one for cooling and one for 24 VAC power)
