I'm changing my old manual honeywell thermostat to a hunter digital. There are more wires attached to the honeywell than what the hunter calls for. I'm pretty sure I need to use the orange/yellow wire that was hooked to the "o" on the honeywell in order to get the cool air. Anybody know the answer to this? Thanks!

Big mistake,, hunter is junk,if not on installation will be within 6 months
