I have a Honeywell Thermostat and Im changing it for a Hunter programmable (24V) model 44110. I am having some problems with the wiring, on the Honeywell I have a G-green,C-blue,R-red,W1 and Y- yellow together,W2 and E-white together, O-orange. On the Hunter back pannel I have space for a G,RC,RH,Y and W. How in the world I can wired that unit, Plzzzzzzzzz help me.:confused:

I believe you have a heat pump system and the new thermostat you bought is NOT for a heat pump system.
If you have a heat pump system
You have the wrong thermostat. You need a 2 stage heat pump thermostat!

Do yourself a favor and get a Honeywell or White Rodgers thermostat for your replacement. Hunter has there problems in my opinion.

Agree, honeywell or WR is the only way to go. Need to match the thermostat to the system.

Switching to a hunter is a down grade,, not a up grade
