I changed my thermostat and my heat won't work. Do I have it wired right? Furnace RC-blue,RH-red,W-white,C-wire from A/C is red and white the red is twisted with the yellow from other wire and capped the white is connected to C, G-green. On the thermostat R-red,RC-blue, O-empty, G-green,W-white,Y-yellow,B-empty. I also have a F/E switch its on F. There is also two tiny white switches on the thermostat for the system type that instructs me what to do . My furnace is gas. Is my system a heat pump?
