I have a Honeywell Chronotherm thermostat which I am planning to replace with a Honeywell TH8321. I need help in wiring.
Currently I have wires connected to G, W2, X, O, Y and R in the current Chronotherm. I understand the relevant connectors in the TH8321 are Y, G, O/B, R, C and AUX. Am I correct about the relevant TH8321 connectors and if so, which will be the corresponding terminals to connect?
I have a Lennox HeatPump with auxiliary gas heating.
