I am a novice and I just bought a house.I would like to change the thermostat to a programmable one.
The old one is a Honeywell TH3201D1004 The wiring goes like -
White wire...Aux terminal
Green wire.... G terminal
Yellow wire....Y terminal
Blue wire....C terminal
Black wire.... nothing
the new Thermaostat is a Honeywell TH6220D1002. It has the following -
L, E, Aux, G, O/B, C, Y, R, Rc
Can you tell me which wires go Where?
