Is this the correct wiring??

fggonzales991 — Fri, 29 Jul 2022 04:35:01 GMT

The old thermostat has the following: New Nest thermostat (3rd gen)

brown -- W1/O/B to W1

black -- Y1 to Y1

green -- G to G

red -- R to Rc

blue -- C to C

white -- W2 to W2/Aux

Let me know if the above wiring scenario is correct.. Thanks

Hi,

So the first time I called up Nest, they suggested the following wiring config, based upon the Carrier model number. I guess they assumed it's just a regular conventional ac unit.

Y1- Black wire
G- Green wire
W1- Brown wire
RC- Red wire
W2- White wire
C- Blue wire

So I called up Carrier directly and was notified I have in fact a heat pump. From that info, Nest gave me the wiring config below.

Y1- Black wire
G- Green wire
O/B- Brown wire
RC- Red wire
W2- White wire
C- Blue wire

Nest thermostat seems to be working as it was designed to do.
