Wiring Help Needed

nawlins — Sat, 30 Jul 2022 21:35:47 GMT

I thought I had it wired correctly, however its blowing hot air when it should be cooling. Can someone help, please?

I have the following wire set up:

Y - Y1

C - C

G - G

R - R

W - W1

*O/B - W2 (B,O)

I have the same setup . The orange and white switched on mine still doesn’t blow cold. So hope you get the answer and I’ll follow

I saw a diagram in the nest app under “Thermostat” scroll down to “equipment” and at the top was “wiring” that showed the 6 connectors and labeled them (cool) (power) (heat) etc. i hope it’ll help.

Yeah, I tried to switch the orange and white as well… still blowing hot on cool setting.

Hey folks,

Thanks for helping, JS10SRT8.

nawlins, I have a few questions to better understand your setup. What system do you have? Do you have a heat pump? If you do, try connecting the orange wire to the OB terminal and the white wire to the W one. Once done, change the hange the O/B wire settings by following the step by step guide here: https://goo.gle/3QpZI2W

Keep me posted.

Best,
