Having problems with your Air Conditioners ?

I am replacing a white rodgers thermostat with a honeywell rth3100c. i have matched my wire as e (brown) to e w2 (white) o aux y (yellow) to y g (green) to g o (orange) to o l blank r (red) t r b blank c blank now i have a blue wire which was hooked up to the x1 on the old thermostat. where does this wire go?

Answers :

Blue (C) or sometimes (B) should be your common wire. Look at your schematics and locate common. Your Brown wire is (E) and is emergency heat, white wire (W) is Auxilary Heat, green wire (G) is fan relay, red wire (R) is power, yellow wire (Y) is Cooling and orange wire (O) is reversing valve.
