I installed a new programmable thermostat last spring, a Hunter 44860. It cools perfectly but will not come on for heat. At the time I thought it was wired correctly, but cannot be sure now. It works perfectly if I switch it to cool. When I switch to heat, I cannot even get the blower fan to run. It is an electric 7-wire heat pump system. Here is how I have it wired:
Wire - Terminal - Usage
--------------------------
Yellow - Y1 - Compressor Stage 1
White - W2 - Aux Heat
Green - G - Fan Control
Red - RC\R - 24VAC
Brown - C - 24VAC Common
Orange - O - Reversing Valve Cool
Black - E - Emergency Heat
There are no jumpers, and there were none on the old thermostat if I recall correctly. Can anybody help me?
