Yikes! Does the blue thermostat wire go to the C terminal?
Hi. I'm trying to install a Honeywell RTH7600 programmable thermostat. I've detached my old thermostat, and I'm trying to figure out how to match up the wires. It's heat and air conditioning, and the old thermostat was a pretty basic, older round variety (also honeywell).
Problem is that I have a red, a white, a green and a blue wire. I can't figure out where the blue wire goes. Does it attach to C (I saw that on another post on this site).
Any help would be MUCH appreciated. I'm in Chicago and it is FREEZING here, and I don't think I'll be able to get the old thermostat reattached (the wire stubs are too short and my screwdriver doesn't fit the screws to take off the plate!)
Wires from wall
R -> R
W -> W
G -> G
B ->?
New thermostat:
R (jumpered to RC)
W
G
C
Y
Thanks in advance!
