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
