Nest thermostat Off mode

If your home will be unoccupied for an extended period of time, like a vacation, you can set your Google Nest thermostat to Off mode. Off mode disables all regular heating schedules, but still maintains Safety Temperatures to help prevent your home’s water pipes from freezing. This way, your thermostat can help prevent possible damage to your home and still work to save you energy. 

Off mode doesn’t turn off the power to your Nest thermostat or your system. To completely prevent your Nest thermostat from activating your home’s system, even if temperatures reach extreme levels, you’ll need to disable your Safety Temperatures. 

Eco Temperature savings compared to Off mode:

  • Off and Eco modes can both help you save energy. You’ll probably save more energy with Off, but it will take longer to return your home to comfortable temperatures. 
  • When your thermostat is set to Eco, it will run heating to try to maintain Eco Temperatures. If you have a system with independent fan control, your fan will also follow its schedule. 
  • When your thermostat is set to Off, it won’t run your fan, and it will only turn on heating in extreme conditions to maintain Safety Temperatures.

How to tell which thermostat you have

 

 

When set to Off:

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

  • 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
    and won’t maintain your Eco Temperatures.
  • Your thermostat will still use your Safety
    Temperatures
    to protect your home during extreme cold temperatures. In these cases, it will start heating automatically.

This should prevent your pipes from freezing when it gets too cold. 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.

Turn off your domestic hot water

Even if your Nest thermostat is set to Off it will follow your domestic hot water heating schedule. Follow the link below to learn how to turn off your domestic hot water heating.

Note: If your domestic hot water hasn’t been heated in the last 48 hours because of a gap in your schedule or if you’ve turned your hot water schedule off, your Nest thermostat will automatically heat your hot water tank to help prevent bacterial growth if Bacteria Prevention is enabled.

Disable heating

To prevent your thermostat from turning on heating, you need to disable Safety Temperatures and Bacteria Prevention.

Important: Your Nest thermostat uses Bacteria Prevention to help prevent the growth of certain bacteria, such as Legionella. It also uses the Safety Temperature to help prevent your pipes from freezing if your home starts to get too cold. When the Safety Temperature is disabled, your thermostat can’t help prevent your home from reaching dangerously low temperatures.

You can set your Safety Temperature to off from the Equipment menu on your thermostat or with the Nest app. For detailed instruction, see the article linked below.
