Hello ricog,


Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look into this for you.


In most cases, Google Nest thermostats can charge their built-in battery using your heating and cooling wires. But there are situations where they may need to connect the Nest Power Connector or a common or C wire to consistently deliver power to their thermostat.


To make sure your system is compatible with Nest, do you mind if I ask for a picture of your current thermostat showing the wiring diagram? Also, could you tell us the make and model of your HVAC system?


I'll look forward for your response.


Best regards,


Hi there,


I know it has been a while but I wanted to ensure that everything is covered here. How's your thermostat now? Were you able to install it?


Please let us know if you have any other questions or concerns.


Best regards,
