How to turn your system off with the Nest thermostat

If you plan on leaving your home for an extended period of time, you can simply set your Google Nest thermostat to Off to stop all heating and cooling unless your Safety Temperatures are reached. If you want to keep your system from coming on no matter what, you can also disable Safety Temperatures.

  • If you’re just leaving for the day, a short trip, or you just want to help save energy, simply let your thermostat automatically switch to Eco Temperatures to help save energy after you’ve left home. This way, your home should be more comfortable when you come back than if you had turned your system off.
  • If you’re going on vacation, or nobody is going to be home for an extended period of time, you can set your Nest thermostat to Off to prevent it from turning on heating or cooling unless the temperature in your home reaches the Safety Temperatures you have set.
  • To completely shut off your home’s heating and cooling system with the Nest thermostat so that it never turns on, even if temperatures reach extreme levels, you’ll also need to disable your Safety Temperatures before setting your Nest thermostat to Off.

How to set your Nest thermostat to Off mode

You should set your Nest thermostat to Off if you want it to help you save energy when you’ll be away for an extended period of time, such as a vacation. Using Off mode can help save energy and prevent possible damage to your home by maintaining your Safety Temperatures if the weather gets extremely cold or hot.

How to disable Safety Temperatures to completely stop heating and cooling

Warning: Your Nest thermostat uses Safety Temperatures to help prevent damage to your home when it gets too hot or too cold. When the Safety Temperatures are disabled, your thermostat can’t help prevent your home from reaching these dangerous temperatures. For instance, your home’s water pipes can burst if the temperature drops below freezing.

You can disable your Safety Temperatures in the Equipment menu on your thermostat or with the Nest app. For detailed instructions, see the article linked below.

Once your Safety Temperatures are disabled you can set your Nest thermostat to Off following the steps in the section above. After you’ve done that, your thermostat won’t turn on heating or cooling no matter how hot or cold it is in your home.
