Set value
:
Switching steps
:
Stop time in hours:
Adjustable limit value
of humidity.
Setting range between
20-80 % RH; step size 5 % RH
(Factory setting
: 45 %)
The threshold
value in % rel. humidity indicates the value set as the limit value
for
the change of
rel. humidity. The adjustment is possible in 5 % steps from 5-
20 %.
If the set value is exceeded
,
the next higher stage will be activated until the value
falls below the
set value.
(Factory setting
: 10 % RH)
If it is not possible to reach the set value within 2 hours
,
the humidity control will
be deactivated for the stop time
.
Setting range between
0-24 hours; step size 1 hour.
(Factory setting
: 2h)

CONTROL
Set value
:
Switching steps
:
Options: The status of the CO
2
control can be configured to
„Off
”, „Stepped” or „Continuous”.
„Off
” CO
2
control deactivated
„Stepped
” CO
2
control active with stepped control logic
„Continuous
” CO
2
control active with continuous control logic
Depending on the CO
2
level, the fans are continuously regulated (fan stages 0
-1-
2
-3-
4) between voltage stage 0 and voltage stage 4. The percentage control is
displayed on the web server page or on the comfort controller KWL
-BEC (
Factory
setting: Continuous)
.
Adjustable limit value of
CO
2
concentration.
Setting range between
300-2000 ppm; step size 50 ppm.
(Factory setting
: 1000 ppm)
The threshold indicates when the next fan stage will be activated
, e.g.
set value
1000 ppm,
switching step 150 ppm. If the measured value is between 850-
1000
ppm,
stage 1 will be activated. If the CO
2
concentration increases to 1000-
1150
ppm,
the next stage will be activated (stage 2).
Setting range between
50-400 ppm; step size 50 ppm.
(Factory setting: 100 ppm)
VOC CONTROL
Set value
:
Switching steps
:
Options: The status of the VOC control can be configured to
„Off”, „Stepped” or „Continuous”.
„
Off” VOC control deactivated
„Stepped
” VOC control active with stepped control logic
„Continuous
” VOC control active with continuous control logic
Depending on the VOC
level, the fans are continuously regulated (fan stages 0
-1-
2
-3-4) between voltage stage 0 and voltage stage 4. The percentage cont
rol is
displayed on the web server page or on the comfort controller KWL

BEC (Factory
setting: Continuous
).
Adjustable limit value of
VOC concentration.
Setting range between
300-2000 ppm; step size 50 ppm.
(Factory setting
: 1000 ppm)
The threshold indicates when the next fan stage will be activated, e.g. set value
1000 ppm, switching step 150 ppm. If the measured value is between 850
-
1000
ppm, stage 1 will be activated. If the VOC concentration increases to 1000
-
1150
ppm, the next stage will be activ
ated (stage 2).
Setting range between
50-400 ppm; step size 50 ppm
(Factory setting
: 100 ppm)
