Trouble wiring a honeywell rth221b thermostat
Hi everyone,
I just bought a honeywell rth221b thermostat. The wires I have coming out of the wall have no labels and are colored as follows: red, green, black, orange and white. I have a gas furnace and central air. The wires were attached to my old honeywell round "manual" thermostat to the corresponding screw labeled with the first letter of the colors of the wires indicated above (I'm pretty sure).
Where should I connect these wires to on the new thermostat--and do I need to connect all of them? The options on the rth221b are: Rh,Rc(which have a jumper), W,Y,G.
Thanks for the help!
