Nest Learning Thermostat Putting out heat instead of AC

BradKlabik

Got my Nest Learning Thermostat yesterday, 3rd Gen. 

Wiring is Y, Y2, W, G, R with a connection to Rc.

I put all the wires into the nest thermostat in same spots. Set up as directions say. When it turns on, it goes to stage 2 cooling and heat comes out. 

How do I fix it without spending 159.99 to have a professional come out and look?

Hi BradKlabik,

 

Thanks for posting and sorry to hear about this situation with your new Nest Thermostat. No worries, help's here! To better understand your situation, could you please send us a close-up photo of your current thermostat wiring and a photo of how your previous thermostat was wired? I'd like to check how it used to be wired.

 

Keep me posted.

 

Regards,

Axel.

Thanks for reaching out Axel.

Here is the Photo of current thermostat wiring. I had to uninstall the Nest Learning Thermostat because we needed the AC working, so this thermostat is currently set up and wired as the link shows. (tried to post a picture, it says I don't have permission to upload images)

Reconnected all thermostat. Turned on cooling. Cold air came out again. 

 

What are the next steps to troubleshoot and fix this now?
