If the central apartment unit is in holiday mode (as per the settings in menu

gram and selects the required ventilation stage based on it.
This ventilation stage is operated daily at the set time (00:00..24:00) for the
specified duration.
Use this operating line to select the time to start ventilation while on holidays.
To start ventilation in holiday mode, the stage selection (page 48) must
be set to Auto.
