I am replacingh my thermostat. it's a honeywell xt302c. im replacing it with a hunter 44660. the wires are different letters. here's what's hooked up on the honeywell and available on the hunter: Honeywell Hunter B W/B R RH W2 RC1 W1 RC Y1 Y1 G G Y/O I have a single stage hreating and cooling system (Trane XV80). Help!

Thanks for your Question,
B- is your common leg,
RH- is your hot to heating
RC1- you will not need
RC- you can use if you remove the jumper for cooling
Y1- you will not need
G- is your fan
O is not needed, wires should be hooked in as follows,
RH- red wire, heating
RC- Yellow wire, Cooling
G- Green wire, Fan
B- Blue wire, for common leg, this one might be a different color so make sure at the furnace which T-Stat wire is connected to Common, you should check all the wiring at the furnace to make sure this pattern of wiring is followed, it should be standard practice to hook them up this way, but not all installers do it, thanks again, please rate this,
