Button
Function
Hold down the + and - buttons for 3 seconds to lock the the +, - and stand-by buttons.
This is confirmed by the letters bL on the display.
Set-point variation and switching off are thus inhibited by the user. Repeating the
sequence will release the buttons.

comfort during the night and the display shows the room temperature.

When switching off the system for seasonal reasons or holidays, proceed as follows:
- Deactivate the appliance
- Set the main switch for the system to Off.

will cause the ventilator to stop.
