I replaced a PRO1 Thermostat with a Nest Learning Thermostat (GEN4), but my cooling is no longer working. Pretty sure it is a wiring issue
PRO 1 WIRING
| C | Brown |
| B | Blue |
| W/E | White |
| R | Red |
| G | Green |
| Y | Yellow |
| Not used | Orange |
NEST WIRING
| Y1 | Yellow |
| G | Green |
| OB | Brown |
| W2/AUX | White |
| C | Blue |
| Rh | Red |
I think I might need to switch the BLUE to the OB and the Brown to the C ??
Any recommendations would be appreciated.
Thanks for the help
