How to tell which thermostat you have

 

You can lock your Google Nest thermostat from the Settings menu on your thermostat or with the Nest app. Locking your Nest thermostat is a good way to keep guests or curious children from changing your thermostat’s settings while still letting you and your family adjust your home’s temperature within the range you’ve set.


Locking your Nest thermostat works a bit differently depending on what mode your thermostat is in when you lock it, and whether you set the lock on your thermostat or with the Nest app. Your Nest thermostat needs to be added to your account in the Nest app in order to lock it.

How to add your Nest thermostat to the Nest app 

Unless someone has the four digit PIN that you create when locking your Nest thermostat, they won’t be able to unlock the thermostat or change any of the thermostat’s settings. Also, anyone you’ve invited to share access to your Nest home will still be able to change any settings or unlock your thermostat with the Nest app.

Important: Even when the Nest thermostat is locked, it will still heat or cool to any temperatures in your schedule, even if they are outside of the locked temperature range. It will also follow your Eco Temperatures.

How it works

Locking your Nest thermostat while in Heat mode or Cool mode

When you lock your Nest thermostat in Heat mode or Cool mode, you’ll set a temperature range after you create a four digit PIN. Anyone can turn the thermostat’s ring to change the temperature within the range you’ve set, but they won’t be able to set the temperature outside of your range or change any of your settings.

Note: When you lock your thermostat with the Nest app, the smallest temperature range is 5º F (for example, 70-75º F). There is no minimum temperature range if you set the lock directly from the Nest thermostat. So if you want to set a smaller range or lock the thermostat to a single temperature you will need to set the lock on the thermostat itself.

Locking your Nest thermostat in Heat•Cool mode

When you set your Nest thermostat to Heat•Cool mode you can choose a temperature range, your thermostat will heat or cool to stay within this range. The smallest range you can set on your thermostat is 2º F (for example, 68-70º F).

When you use the Nest thermostat or the Nest app to set the lock you’ll create a PIN, after you set a PIN your thermostat will be locked to the range you’ve chosen. You will not be able to adjust the temperature by turning the thermostat’s ring, and you won’t be able to change any settings from your thermostat without entering the PIN and unlocking it.

If you need to change your temperature range or settings you can use the Nest app or unlock your thermostat.
