second nest thermostat

sideline2 — Mon, 24 Jan 2022 23:17:43 GMT

I installed a nest thermostat. It was working fine. I want to install a second nest thermostat for a different zone in the same home. However, it says I need to have a c connector. I didn't have to have that for my first one. So I couldn't finish the setup process and the second nest thermostat is not connected to wifi. I get a network error on the thermostat. Do I need a c-connector?

Hey sideline2,

Thank you for posting here.

Your Nest Thermostat needs to have a stable power from your system to keep it running and connected to your WiFi all the time. It is recommended to have a common wire to prevent your thermostat from turning off and disconnecting from WiFi.

For the meantime, you could try to charge your second thermostat on a USB and try to complete the setup. You could check out this link to know more about common wire.

Regards,

Ryan
