Cooling instead of heat.

I installed a Nest Leaning Thermostat last week. We have had ac on since. Now we need heat. I have reset. And have changed from O to B still no heat. Photos to show factory, Nest. Any help would be great. Thanks.

Your RED wire goes in Rh not in Rc.

That didn't do it either. Just putting Cpi back on. Mess with it when I find more info. Every way I had it should of worked.

It doesn't matter but the Rc terminal is preferred.

Give this a try

White - W to W2/AUX (set as AUX heat)

Yellow - Y to Y1

Green - G to G

Red - R to Rc (jumper to R not needed)

Blue - B to OB (you will have to change the valve setting)

Brown - C to C

Because your system uses the B wire for the reversing valve relay you have to change its setting.

  1.  On your thermostat, go to Settings.
  2. Select Equipment.
  3. Select Continue > Continue.
  4. Select Heat Pump.
  5. The Nest Thermostat defaults to an O setting for heat pumps. 
    • If the O option is highlighted, select B.
  6. To make sure the issue is resolved, test your heating and cooling again.
