About locking and unlocking
If required, it is possible to lock the buttons of the main user
interface, making it impossible for the user to operate it. For the user
to be able to change setpoint temperatures, the simplified user
interface or an external room thermostat is then required.
You can use the following locking modes:
▪ Function lock: Locks a specific function to prevent people from
changing its settings.
▪ Button lock: Locks all buttons to prevent users from changing
settings.
