Hello @ManuNarang, 

Thank you for reaching out to the community! I understand you're interested in getting a Nest thermostat and have questions about compatibility. I appreciate you sharing the photo of your current thermostat. I'm happy to help you. 

Based on the image your system will need a "C" wire or a Nest Power Connector to be compatible with a Nest thermostat. 

Let me know how it goes. 

Best regards, 

Eitan
