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. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
