14.6 DEMAND-DRIVEN CONTROL OF
THE AIR VOLUMES
The air volume flow can be either defined
manually or controlled via a scheduler –
see Section 8, item 8.1.4, page 15 .
Up to two dierent additional sensors may
be optionally installed for demand-driven
control.
14.6.1 CO
2
sensor Air volume flows are generally specified
via the values selected in the scheduler or
via manually selected values. If a CO
2
sen-
sor is configured via the data logger, the
air volumes are increased automatically as
soon as the preset CO
2
threshold value is
exceeded (default setting 1000 ppm).

14.6.2 Humidity sensor Air volume flows are generally specified
via the values selected in the scheduler or
via manually selected values. If a humid-
ity sensor is configured via the data logger,
the air volumes are automatically increased
when the preset maximum relative humid-
ity is exceeded, and they are automatically
reduced if the value falls below the preset
minimum relative humidity. (Default setting
min. 30 %, max. 60 %).
