Hello,
Having issues wiring my new thermostat. I've got the heat/ac to switch on but I had to mess with it some. I have a G, R, B, Y & W wire coming to my thermostat. My thermostat has a G, RC, RH, Y/O, W/B & Y1 port.

This is what I messed with:

AC worked: G to G, R to RC, B to RH, Y to Y/O, W to W/B, nothing to Y1
Heat worked: G to G, B to RC, R to RH, Y to Y/O, W to W/B, nothing to Y1
Both at once: G to G, Jumpered R to RC & RH, B to Y/O, W to W/B, Y to Y1
Best: G to G, Jumpered R to RC & RH, y to Y/O, W to W/B, B to Y1


From what I can gather the wireing usually goes:
Red - power
Blue - common
White - gas
Yellow - AC
Green - Fan

From what I can gather the ports are:
G - Fan
RC - 24v Cool
RH - 24v
Y/O - AC Compressor or Reverse Valve operating in cool mode
W/B - Heating or Reverse Valve operating in Heat mode
Y1 - Heat Pump compressor

I just want to make sure that I'm wired correctly because I have a gas funace.

I'm wired to the Best: setting atm, will I have any problems with this?

Thanks for your input,

J O

Hooked up my new thermostat 44155c and when my furnace comes on my air conditioner kicks on, what's the problem

Call Hunter tech support. They helped me with this and it was free for me. Issue is you have to many wires. You don't need a jumper in the last slot. Call support!!
