5.4.5 Automatic after-run
The cooktop extractor continues to run at a lower level
and switches off automatically after 20 minutes.
5.4.6 Filter service display
The filter service display is active after 200, 300 or
400 operating hours, depending on the filter unit fitted.
The activated charcoal filter has reached the end of its
service life (with recirculation only) and the grease filter
components need to be thoroughly cleaned.
After the cooktop extractor is switched on, F flashes
on the control knob display.
The filter service display is shown every time the
cooktop extractor is switched on and remains active
until the filter has been changed and the filter service
display has been reset.
The cooktop extractor can still be operated without
limitations.
The filter service display can be deactivated on a
one-off basis or completely reset in order to use the
cooktop extractor.
INFO
Irrespective of the filter service display, the grease
filter components require regular cleaning (see
Cleaning and maintenance section).
5.4.7 Interface communication
The internal interface can be used for extended control
options. This has a ‘Home In’ and a ‘Home Out’ contact
(see the Installation section).
The ‘Home In’ contact can be used for the signal input
from external switch devices (e.g. window contact
switch).
The ‘Home Out’ contact can be used to control
external installations.
5.4.8 Safety shut-down
The cooktop extractor shuts down automatically after an
operating time of 120 minutes with no changes in power
level.
5.4.9 Crush protection
The electrical cover flap on the cooktop extractor has
crush protection.
If the cover flap is blocked while it is opening or closing,
the movement is stopped automatically. The cover
flap moves back to its starting position (see Operation
section).
5.4 Functional principle of the
cooktop extractor
5.4.1 Power control
The power levels are controlled by turning the knob ring
to the desired power level.
5.4.2 Power setting
The cooktop extractor has a power-enhancing power
setting. This power setting makes it possible to suction
away high levels of cooking vapours more quickly. After
9 minutes, the power setting is automatically switched to
power level 9.
5.4.3 Automatic cooktop extractor function
The automatic cooktop extractor function adjusts the
extraction performance automatically to the highest
power level for all cooking zones connected.
Function Power levels
Cooking level 1 2 3 4 5 6 7 8 9 P
Extraction power 4 4 4 4 5 6 7 8 9 P
Tab. 5.2 Extraction performance and cooking level
If the power level of the cooking zones is changed,
the automatic cooktop extractor function adjusts the
cooktop extractor performance after a 30 second delay.
Once the cooking session is complete, the automatic
after-run is activated.
After the automatic after-run period, the cooktop
extractor switches itself off automatically.
5.4.4 Sensors
The cooktop extractor is fitted with sensors near the
cover flap and the grease filter.
Position sensor for cover flap
The cover flap sensor detects the position of the cover
flap.
If the cover flap is closed, the cooktop extractor is
deactivated.
If the cover flap is open, the cooktop extractor can be
used.
If the cover flap is removed, the cooktop extractor can
be used.
Grease filter position sensor
The grease filter sensor detects whether the grease filter
is properly fitted.
If the grease filter is missing or fitted incorrectly, the
cooktop extractor is deactivated.
INFO If the grease filter has been removed, for example
for cleaning purposes, the cover flap can still be
closed.
