What do I do with the orange wire? I have a heat pump/ac unit and am switching from a non-programmable Honeywell

Which terminal did the orange wire come off on the old thermostat

OK,, once again,, hurry before its to late,take that piece of junk hunter tstat back to where it come from .it is junk and even if it works it won`t last long.get you another honeywell unless you just like waisting your money

I think we are all on Honeywells payroll. LOL

I wish I was on the honeywell payroll. Lol

But buying a cheap thermostat is like buying a cheap car, you never know how long it will last, and the first time you take it for a drive, it usaully fails. Honeywell will stand behind their products.
