Hi LEidens, 

I wanted to stop by and see how I could help.

How's it going with your Nest Thermostat? Were you able to read the information that CoolingWizard has shared? Also, can you tell us what type of Nest Thermostat you installed? If you can provide that here, I'll look it up and see how I can continue to help you here.

Thanks for the help here, @CoolingWizard and Jeran.

Best, 

Zoe
