How to Lock and Unlock My Wi-Fi Thermostat for Central System?

The thermostat is unlocked by default, allowing manual control. It is possible to lock the buttons via the Neviweb app to prevent unintended changes, with options for full or limited locking. Unlocking without the app requires unplugging the router, resetting the thermostat, then reconnecting the device. This feature is useful for rentals or families with children.

Locking and Unlocking with the App
The keypad of a thermostat is “unlocked” by default. This means the buttons (or keypad) are “functional” and the thermostat can be controlled manually, directly from the device. It is possible to lock the thermostat buttons to prevent any unintended setpoint changes.
 
 
 
 

You can lock the buttons on your device by selecting this option in the device settings within Neviweb.

 

 

 

Locking Options

The buttons can be locked with different options (full lock or limited lock, the latter only allows changing the setpoint and prevents configuration and device disconnection).
