5.36 CARBON FILTER STATE INDICATION
(RECIRCULATION MODE ONLY)
The hob touch control includes a filter timer that reminds that it is important to clean the
carbon filters on a regular basis. The filter run time is always counted when the fan is running,
even during the after-run. After the time has elapsed a flashing "C" is displayed on the fan
power setting diplay.
During the after-run the "C" is not shown: it pops up again when the hob is switched on.
The filter display can either be acknowledged or reset:
• Short press on the fan power setting display means acknowledgement. The display
appears only after switching the hob off and on again.
• Long press for 3 seconds on the fan power setting display causes a reset of the filter
timer. A confirmation tone will be heard and the "C" will be displayed for 2 seconds
before the standard display returns.
