The several days before. I'm looking for information on the Honeywell RTH6580WF Wi-Fi 7-Day Programmable Thermostat, so i have to tell.
I'm not even close to the kind of home improvement. so, if things go south, I'm in trouble. I looked over the box of Honeywell and Honeywell said wisely your HVAC wiring to the thermostat must have a "thread" or the new thermostat would not receive the power and would not work. so being the prudent person that I am I asked three wandering separated boys Home Depot if there was anyway I could "say" if I had a little C. the first guy said, "oh if you have AC you must have a C wire."
