Hi vinodk,

Thanks for checking it with us. I'm sorry for the delay. A few questions: in what country are you located? What is the make and model of your system? If you have the Nest Thermostat 2020, you might need to have a C wire or a Nest Power Connector. 

Best,

Jenelyn

Hi there vinodk,

You can visit this article on how to install a Nest Power Connector to your system. Also, you can try clicking this link then scroll down to your response and hit reply. Check for the camera icon or click the three horizontal dots to expand the toolbar. From there, you'll be able to reply and share a photo.
