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 Nest thermostat to Off to stop all heating unless your Safety Temperatures are reached. If you want to keep your system from coming on no matter what, you can also disable the Safety Temperature and Bacteria Prevention for domestic hot water.

  • 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 Temperature 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 unless the temperature in your home reaches the Safety Temperatures you have set.

  • To completely shut off your home’s heating 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.

Turning 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.

How to disable Safety Temperatures and Bacteria Prevention to completely stop heating 

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.
