Nest thermostat

[Mstrem]

Our furnace keeps running after it reaches set temperature. I took the nest off the wall today and then it finally turned off. We don’t have a c wire. If we get one will it fix this issue?

Hi Mstrem,

Thanks for posting here in the Google Nest Community. We'd be happy to take a look into this for you. Let’s gather more information about it before we can conclude if you really need a C wire or not. Please answer the following:

1. Are you from North America or Europe?
2. What type of Nest Thermostat do you have?
3. What is the make and model of your HVAC? 
4. If you can, please place back the Nest Thermostat on the base and gather power reading.

For the Nest Learning Thermostat and Nest Thermostat E:

1. Press the thermostat ring to bring up the Quick View menu.
2. Turn the ring to Settings and press to select.
3. Turn the ring to Technical Info and press to select.

For the Nest Thermostat 2020:

1. Tap the touch bar to bring up the Menu view.
2. Slide your finger down to Settings, then tap to select.
3. Slide your finger to Equipment > Power Info.

I look forward to your response.

Cheers,

Renz

We were able to figure it out, thank you.
