b . Daily/weekly programme
The timer mode has an adjustable weekly programme with two operating intervals for each ventilation stage on each
day of the week.
Special feature Controller AIR1-BE Touch: Four operating intervals for each ventilation stage on each day of the week.
The following ventilation stages/functions are available:
• Timer Reduced
• Timer Normal
• Timer Boost
• Timer VOD (accessories required, sensor-controlled operation)
• Timer Recirculation (accessories required)
If no ventilation stages/functions are selected, the unit will not run (standby).
Set weekly programme:
• Log on as User or Admin
• Call up the timer settings menu
• Call up the selected timer
• Set timer for all days

Timer priorities (highest priority first):
• Timer Boost
• Timer Normal or VOD (higher ventilation requirement)
• Timer Reduced
• Timer Recirculation
If the set timer times overlap, e.g. if the "Boost" timer and the "Normal" timer are programmed for the same time, the
timer with the higher priority will be activated and the ventilation unit will be operated at the "Boost" ventilation stage.
Special features in case of simultaneous programming of recirculation timer and VOD timer:
• If the VOD timer and recirculation timer are active at the same time and no air quality sensors reach the sensor limits
(Boost ventilation), the unit will switch to recirculation mode.
• If a connected sensor reaches the sensor limit, the recirculation mode will stop and the unit will run in sensor-con-
trolled operation (VOD).
• If the sensor signal reaches the sensor limit, the unit will switch back to recirculation mode.
• The recirculation mode will not work if the reduced, normal or boost timers are running at the same time, since it
has a lower priority.
c . Holiday
Up to 24 separate holiday periods can be set for a whole year.
Set holiday calendar:
• Log on as User or Admin
• Call up the "Timer settings" menu
• Holiday according to programme "Set daily/weekly programme". The ventilation unit always runs pursuant to the-
holiday settings during holiday periods
• Call up holiday calendar
• Set holiday periods

4 .0 .3 Sensor-controlled operation (VOD - Ventilation on demand)

The sensor-controlled operation function (Ventilation on demand = VOD) must first be set in the commissioning
assistant.
The sensor-controlled operation only works in "Constant volume flow mode" or "Constant speed mode". The sen-
sor-controlled operation function can only be activated using the VOD timer.
The sensor-controlled operation is only used to achieve improved room air quality. In this respect, the use of air quality
sensors (KWL-CO2, KWL-FTF, KWL-VOC) is required. This mode can also be used for multiple connected sensors.
A signal converter (AIR1-SK) must be used if more than 3 sensors are to be connected. The sensor with the highest
ventilation requirement determines the ventilation operation mode.
