Confirming wiring after install

[Annacate]

I just finished installing my Nest Thermostat. I initially did the wiring and/or setup in the app incorrectly and was getting hot air from the vents when I had it set to cooling. I changed it and am now getting cool air, but I can’t help but feel worried that I set it up wrong. Would love some confirmation that it looks correct.

Previous wiring:

Nest wiring:

And in the app setup I selected Y/Y1, G/G1, R, C, W2, and O/B.

Did I do this correctly? In case it’s important, I have an electric forced air unit. Thanks in advance.

Hi Annacate,

Thanks for posting in the Google Nest Community forum. I'd like to ensure the compatibility and wiring configuration of your system to the Nest Thermostat 2020.

Do you happen to know if you have a heat pump system? Please provide your system's make and model. Also, could you please take a photo of the wires connected to your system's control board? Make sure that the labels of the wires are visible. It will help us to check what type of system you have. 

Best,

Jenelyn

Hi Jenelyn,

I believe it is a heat pump system, yes. It's made my Amana, and the model number is ASZ160241LB. I'm unsure what other info you're asking for? The photo of the original wiring from the old thermostat is included in my original post. If you can't tell what the labels are along the top row ("Conventional"), they were as follows:

• white wire: W2
• green wire: G
• blue wire: W
• brown wire: C
• yellow wire: Y
• red wire: R

Thanks so much!

Hi there,

Thanks for the information provided above. I confirmed that you have a heat pump system. The labels that you'll follow are on the bottom part of your previous thermostat.

Your Nest Thermostat has the correct wiring configuration:

• Y - Yellow (Cooling)
• W - White (Auxiliary) 
• G - Green (Fan)
• C - Brown (Common)
• *OB - Blue (Reversing Valve)
• R - Red (Power)

Please let me know if you still have questions or concerns, as we'll be willing to help. 

Cheers,

Jenelyn
