Priorities Hours (Highest Up):
•
Timer boost speed
•
Timer normal speed
•
Timer VOD
•
Timer reduced speed
•
Timer recirculation
If the timers overlap, for example, a boost speed time and normal speed timer programmed at the same time, the timer
operation with the higher priority will run and the ventilation unit will run in the boost speed ventilation level.
Special feature with simultaneous programming of timer recirculation and timer VOD: Sensor based recirculation activation:
If the timer VOD and timer recirculation are active at the same time and no air quality sensor reaches the upper sensor limit
(boost speed ventilation), the unit is in recirculation mode.
When a connected sensor reaches the upper sensor limit, the recirculation mode stops and the unit runs on Ventilation on
demand mode (VOD).
If the sensor signal drops to the lower sensor limit, the ventilation unit switches back to recirculation mode.
Recirculation mode does not work if timer reduced speed , timer normal speed or timer boost speed are in operation at the
same time because it has a lower priority.
c. Holiday
The Timer settings has a programmable holiday calendar with up to 24 holiday periods per year.
Setting the holiday calendar:
•
Login as user or admin
•
Calling the Timer settings menu
•
Holiday Day according to “setting of the Days/Week programs” program. The ventilation unit always runs during all
holiday periods (max. 24) with the settings of the holiday day.
•
Visit Holiday Calendar
•
Define vacation periods
d. Extended running
The switching contacts for the levels Minimal, Normal, Intensive, Recirculation have a follow-up function.
The ventilation unit runs for the set time after the last closing of a switch contact. Thus, a button function is also possible, so that
the device is always operated for the set overrun time with a single push of a button (closing a switch contact).
If the extended run time is set to 0, the ventilation unit only runs as long as the corresponding switch contact is closed.
