    Wiring Scheme on thermostat
    I have a Honeywell T841 A 1712 thermostat which my brother was doing me a favor by changing the unit out to a digital unit. Unfortuantely, he removed the wiring before labeling the wire scheme and now I want to go back to the origianl honeywell T841 but do not know what wires go where. I do not want to guess but the wires that are coming from the wall are: Black, Blue, White, Red, Green, Orange, Yellow and Brown (But brown is not being used). NEED HELP!!
