Hey bruce, 

Thanks for reaching out to the Google Nest Community. 

N260 means that you need to have a C wire installed or if your system already has one, it is not providing enough power to your thermostat. Also, you might need to update the wiring info in the app if you just recently added a C wire or a Nest Power Connector. Check out this guide: https://bit.ly/3IA1qLm

Best,
