C-Wire Added

Originally I did not have a C-wire when I installed the nest. Since then I added the c-wire but the thermostat does not see it. Do I have to remove the device and reinstall for it to see the c-wire. Or will a factory reset do it?

Hi @mrelmo,

 

Thank you for reaching out to the community. 

I understand how difficult it is that the Nest Thermostat is not detecting the C-wire. Wiring issues can be tricky, but let's see if we can get it working.

To help diagnose the problem, I'll need some information:

  • What type of Nest Thermostat do you have? (The model name is usually on the back of the device.)
  • Do you see any error messages on the screen?

In the meantime, you can try a factory reset. This will erase all your current settings, so be sure to note them down beforehand if needed. Here's how to perform a factory reset (consult your manual for specific instructions, if needed):

  1. Go to the Nest Thermostat settings menu.
  2. Look for the option labeled "Factory Reset" or "Reset" (depending on your model).
  3. Follow the on-screen instructions to confirm the reset.

Once the reset is complete, please try reconnecting the C-wire and see if the Nest Thermostat detects it. Let me know the results, and we can troubleshoot further if needed.

 

Best regards,

 

Jorge.
