How to restart or reset a Nest thermostat

Restarting your thermostat can resolve some issues, like a slow or frozen display, or help it get reconnected to the internet. If you need to clear out some or all of the learning about your home, schedule, or personal settings, you can reset your Nest thermostat.

Schedule

Choosing this option will clear out your entire temperature
schedule. Any setpoints that your thermostat has learned, or
that you’ve created, will be erased.
 You’ll need to create a
brand new schedule from scratch, or wait while your
thermostat learns your new schedule
.

Note: If you’re using a Nest Thermostat E and you have Auto-Schedule disabled you’ll see the option to reset to a blank
schedule as above or choose a default schedule. A Default
schedule is an average schedule based on your region with
setpoints already added for you.

Important: If your Nest thermostat controls your hot water,
choosing the schedule option from the reset menu will also
remove any schedule you’ve set for your domestic hot water.
You’ll need to set up your hot water schedule again.

Away

Your thermostat learns how how often you walk by to help
better use Home/Away Assist. If you choose this option, all the
learned information on your thermostat will be reset.

If you move your thermostat to a new location in your home, or
if you’ve had your home remodeled, you should use this option.

days.

Resetting the network will remove all of the network
information from your thermostat. Your thermostat will no
longer be connected to the internet and it will forget your Wi-Fi
password.

How to manually restart if your Nest thermostat is frozen or stuck

We only recommend this method if your thermostat is stuck or frozen, and you can’t reach the menu to restart your thermostat as described in the section above.

Important: Manually restarting your thermostat is similar to turning off a computer instead of shutting it down, so your thermostat could lose some unsaved information.

To manually restart the Nest thermostat:

  1. Press your thermostat ring and hold it down until the screen turns off (about 10 seconds). Then let go of the ring.

  2. Press and release the ring to turn it back on and complete the restart process. You'll see the Nest logo when it begins to start up. The screen will turn on as it finishes.

Restarting or resetting the Heat Link

In some cases, you may also want to restart or reset your Heat Link. This can be useful when troubleshooting the connection between the Heat Link and your Nest thermostat. You may need to reset the Heat Link to factory defaults if you've had your Nest thermostat replaced.

While you’re adding your thermostat to the app, if it gets stuck, the app will tell you to erase your thermostat’s previous settings in order to continue with setup.

Note: Only follow these steps if the app tells you to erase your thermostat’s previous settings during setup. These steps won’t work any other time.

  1. Press your thermostat ring two times.
  2. Then press and hold your thermostat ring for five seconds.
