Locking your Nest Thermostat
When your thermostat is locked, anyone can turn the thermostat’s ring to change the temperature within the range you’ve set.
The range you can select depends on whether you set the lock on your thermostat or with the Nest app. When you lock your Nest Thermostat with the Nest app, the smallest temperature range is 2.5ºC (for example, 20-22.5ºC). There is no minimum temperature range if you use the Nest Thermostat to set the lock. If you want to set a smaller range, or lock the thermostat to a single temperature, you will need to set the lock on your thermostat.
Important: Even when the Nest Thermostat is locked, it will still heat to any temperatures in your schedule, even if they are outside of the locked temperature range. It will also respect your normal Eco Temperature.
