Question about Honeywell Heat/Cool Thermostat
It sounds like you have a heat pump, o (orange) is usually used to power a reversing valve in your outdoor unit for cooling. But just in case you don't here is a little info Rh-power for the heating circuit, W- completes heating circuit, Y to your outdoor unit for cooling, Rc- power for the cooling circuit, and G power to your high speed fan.
O for your heatpump
C is 24v common for cooling circuit
If you do have a heat pump, you will have to get a thermostat that is compatable with heat pumps. Hope this helps
