Learn about Off mode on the Nest thermostat

Off mode doesn’t turn off the power to your Google Nest thermostat. Instead, Off disables all regular heating and cooling but still maintains your Safety Temperatures to prevent your pipes from freezing and your home from getting too hot.

Off mode is useful during times when you know you’re
not going to be using your heating or cooling system for
an extended period of time, like a long vacation. It’s
similar to Eco Temperatures because your Nest
thermostat will ignore your heating and cooling

When set to Off:

  • Your thermostat will stay connected to the internet
    so that you'll still be able to control it with the app
    and it can automatically download software

  • Your thermostat will continue to record your Energy History. You'll see an Off icon in the app when you check your history.
  • Your thermostat won't turn on heating or cooling and won't maintain your Eco Temperatures.
  • Your thermostat will still use your Safety Temperatures to protect your home in case of extreme hot or cold temperatures and start heating or cooling automatically.

This should prevent your pipes from freezing when it gets too cold and should keep your home from overheating when it's very hot outside. You'll also get Safety Temperature alerts on your phone.

Note: The Nest thermostat has heating Safety Temperatures enabled by default to help protect your home from getting too cold. You will need to enable cooling Safety Temperatures if you want your Nest thermostat to help protect your home from getting too hot.

How to turn the thermostat Off

You should set your thermostat to Off if you want to help save energy when you'll be away for an extended period of time.

Note: You won't be able to turn on your fan if the thermostat is Off. But if your system has a separate fan wire, you'll be able to turn your fan on without turning on your heating or cooling system.

Temperature ranges for Safety Temperatures and Eco Temperatures 

Safety Temperatures and Eco Temperatures have different temperature ranges:

  • Set your Eco Temperatures to help you save energy if you're away from home for a short time.
  • Set your Safety Temperatures to help protect your home from getting hot or cold enough to cause damage.

The table below shows the upper and lower temperatures you can choose for each mode:
