How the Nest thermostat’s Safety Temperatures work

<= Back

Safety Temperatures can prevent your home from going above or below certain temperatures by turning on heating or cooling when the set limits are reached. This helps ensure that your pipes won’t freeze and that your home won’t become damaged by excessive heat. Your Nest thermostat will follow your Safety Temperatures even if it’s set to Off, Eco Temperatures, or your home is set to Away.

Safety Temperatures are great for helping protect a second home, if you have one. They can prevent the pipes from freezing while your home is unoccupied, even if the thermostat was left in cooling mode or doesn’t have a heating schedule. You’ll never have to worry if you’ve set the thermostat correctly before you leave, and as long as your Nest thermostat is online you can check your home’s temperature from anywhere with the Nest app.

Safety Temperatures are different from the Eco Temperatures set during thermostat setup. To learn more about Eco Temperatures follow the link below.

Safety Temperature Notifications

If the room temperature drops below the set Safety Temperature, your Nest thermostat will automatically start heating. Similarly, if the temperature goes above the set Safety Temperature, your Nest thermostat will automatically start cooling.

In each case, you’ll get a push notification on your phone or tablet, as well as a message in the Nest app. Once temperatures return to normal levels another notification will let you know.

Important: Notifications about Safety Temperatures rely on an active Wi-Fi and internet connection in your home at the time of the notification. If your Wi-Fi network is down during the time when the Safety Temperature is reached, you will not receive the notification. Your thermostat will continue to heat or cool while your home Wi-Fi network is offline.

How to set Safety Temperatures

The Nest thermostat’s default heating Safety Temperature is 40° F (4° C) to prevent your home from freezing. The Nest thermostat doesn’t have a default cooling Safety Temperature.

You can set Safety Temperatures on your thermostat or with the Nest app:

On your thermostat:

– Press the thermostat’s display to bring up the Quick View menu.

– Select the Settings icon .

– Press Continue on the Your System screen.

– Choose Safety Temp to view your Safety Temperatures.

– Use the ring to select the heating or cooling Safety Temperature you’d like to change and press the ring to choose it. Turn the ring to change the temperature and press the ring to confirm your change.

Note: You can disable one or both of your Safety Temperatures by turning the dial to off when choosing a temperature.

–  Choose Done to exit the menu.

With the Nest app:

– Select your thermostat.

– Tap the Settings icon .

– Tap Equipment.
