I am installing a honeywell RTH3100C thermostat to my carrier 50HX heat pump and it will only blow hot air with the switch on cool. The compressor kicks on and it blows cold air to the outside of the heat pump. Am I hooking up wires wrong? it's got 2 sets of wires one set has a bundle of 7 wires an the other has 3
Coming out of the heat pump I have orange, green, brown, white w/ blue stripe, and a light blue wire in one bundle and the other bundle has a red, light blue and a white wire and the thermostat has E,AUX,Y,G,O,L,R,B,and C connectors..
