I replaced my thurmostat at the begining of summer. The AC worked just fine, if I put the unit to fan it works fine. I just tried to turn on the heat, and the heat does not come on...

My old thurmostat had the letters W O G R C Y

New has RH RC W Y G

Now I have the AC working, when it gets hot it auto turns on, everything works great. But when cranking the heat up to 80 when the house temp is 70 it won't turn on. Since the AC works just fine I would assume my problem is somewhere in the heat side, RH and W... I tried swaping the wires but it didn't seem to help either...

Do you have a heat pump system?

Sorry for the delay. No, its a natural gas system.

What are the color of the wires you have hooked up to RH RC W Y G and is there a jumper wire between RH & RC?
