By default, the 1st day of the year is a day that is part of the holiday period.
The “holiday” time period must be set in advance.
The holiday period is defined by a start day/month and an end day/month. Up to 12 different periods can be set. The
so-called “holiday” period can therefore extend over several days, weeks or even months.
13.4. Recommendations for time schedule settings in the LOBBY version
When the ventilation unit is operated at constant pressure (LOBBY), the air distribution network usually imposes a single
operating pressure. As a result, a single setting for supply and return pressure is sufficient. It is therefore not necessary
to activate the normal operation period, and only the reduced operation period can be used. This therefore ensures that
the night cooling function remains in operation if it is used.
However, if the normal operation time schedule is required, it should not overlap with the night cooling time schedule
(00:00 - 07:00) to avoid disrupting the operation of the night cooling function.
Below is an example of time schedule (left) and ventilation (right) settings for the optimal operation of a LOBBY control:
13.5. Recommendations for time schedule settings in the DIVA and QUATTRO versions
The time schedule associated with the normal speed does not allow the fan speed (DIVA) or the air volume (QUATTRO)
to be regulated according to the CO
2
level.
In order for the CO
2
control to function properly, the desired time schedule must be linked to reduced operation only. The
reduced speed must therefore always be programmed during the period when the zone is occupied, and the rest of the
time to ensure minimum air circulation, which results in the following setting:
