My current Honeywell thermostat has 2 wires. One is Red to the R connection and a Blue wire to the C connection. It controls both heat and AC. Will my new Nest Learning Thermostat work with this set-up? I assume that the Red is for heat and the Blue is for AC and that the Nest will run off its internal battery. Thx for any feedback.
