3.1 Connectivity options
The central control unit SEC-20-BF can be used for operating the fans of the SEVi 200 and
SEVi 160 series. Moreover, theSEVi 160DUO MINI (available from autumn 2016)can be
operated by using the SEC-20-BF.
Furthermore, the central control unit can be used as a humidity sensor.
Specific feature: Die terminal assignment of the spring-type terminals depends
on the fan models to be operated!
The fan terminals on the rear side of the operator control unit are separated in air incoming
side (Zu) and air discharge side (Ab) on the one hand, and on the other hand in top (oben)
and bottom (unten).
Air income and air discharge refer to the start direction
or the intensive brief ventilation operation. A fan which
is connected on the air incoming side, will work
according to the air incoming mode in intensive brief
ventilation or permanent ventilation operation; a fan
which is connected on the air discharge side will
transport the consumed air correspondingly.
The bottom connecting terminals must be used for operating the SEVi 160DUO MINI
ventilation system.
Note: SEVi 160 fans (without SEVi 160DUO MINI) can be operated in the
configurations 1 - 3 by using the top and bottom terminals!
The sole operation of the SEVi 160DUO MINI or the simultaneous
operation of SEVi 160 systems and SEVi 160DUO MINI fans requires
the selectin of one of the configurations 4 - 7 and the appropriate
assignment of the connecting terminals!
Depending on the device types used and the operating modes desired, the configurations
indicated on pages13/14 under 3.7 are to be set.
Note: An individual cable (LIYY 3 x 0.5 mm² or 3 x 0.75 mm²) is to be laid from each
fan (SEVi160/200) to the distributor board! Two cables must be laid for the
double fans SEVi 160 DUO and SEVi 160DUO Mini!
max. length of the in-wall cable: 30 m

3.8 Activating/changing the humidity feature
The SEC-20-BF central control unit can be operated optionally with or without humidity
control.
The humidity control distinguishes between five different conditions:
Condition
Indication via LED in the setting mode
Humidity threshold
(RH%)
Humidity control
off
All LEDs off
-
1
LED fan stage 1 flashes
50
2
LED fan stage 2 flashes
55

60
4
LED fan stage 4 flashes
70
To activate the humidity control or to set another humidity threshold, the following steps are
to be taken:
Keep the keys “Alternating operation”and “Filter
change” pressed for 5 seconds. The control changes to
the activate/deactivate mode.
The condition currently set is indicated by the LED of
the fan stages (see table).
The desired condition of the humidity control can be
selected by pressing the key “Fan stage”.
Press the keys “Alternating operation” and “Filter change” anew for at least 5 seconds to save
the setting selected. Then, the control unit returns again to normal operation.
Noteto humidity control:
In the activated mode of the humidity control, the room humidity is continuously measured.
If the value which has been set for the humidity threshold is exceeded, the fan stage of the
fans connected is increased by one stage until fan stage 4 is reached. The stages are gradually
increased at 15-minute intervals.
If the value measured is lower than the humidity threshold set (minus a hysteresis of about
5%), the fan stage is decreased gradually again down to stage 1.
The manual change of the fan stage is still possible. However, the manual setting will be
corrected at 15-minute intervals if the humidity control is switched on.
Delivery status: configuration 1, humidity control off

In order to ensure that the double frame fits, only the circumferential strip must be removed.
Important!
The surface-mounted housing must be provided with a separating element in the centre to
ensure the proper functioning of the humidity analysis!
Afterwards, the four screws can be used for fixing the lower part on the surface-mounted
housing.
