Hi Tillu23,

Thanks for checking it with us. I'd like to know more about it. A few questions: what type of Nest Thermostat do you have? In what country are you located? Do you see any messages or codes on your thermostat or in the app? Are there any other Nest devices connected to your Wi-Fi network? 

Best,

Jenelyn

I have Nest Learning Thermostat - 3rd gen (latest). Location: California(United States). It is connect to Wi-Fi and No errors are showing up. Looks like it is not able to communicate to the HVAC.

Hi folks,

@Tillu23, chiming in, and thanks for the information. Could you send us a photo of your previous thermostat's wiring configuration and a photo of how you connected the wires to the Nest Learning Thermostat base so we can take a closer look? I'll look forward to your response. 

I appreciate your help, Jenelyn. 

Thanks,

Zoe
