Immediate switching-OFF of all cooking zones can be
achieved anytime by means of the ON/OFF key. In the
standby- mode an "H" appears on all cooking zones which
are "hot". All other cooking zone displays are not
illuminated.
Wattage settings
The output of the cooking zones can be set in 9 steps which
are indicated by the figures "1" thru "9" by means of LED
sevensegment-displays.
Automatic heat-up function (selectable)
When the automatic heat-up function is activated the
wattage of the cooking zone is at 100 % ED for a certain
heat-up time which is dependent on the selected
(continuous) setting. At the end of the heat-up time the
electronic control switches back to the preselected
simmering setting.
Starting process of the automatic heat-up:
- Control is ON and a cooking zone will be selected
- The automatic heat-up will be activated by operating the
PLUS-key for a second time.
- The requested continuous setting will be selected with the
PLUS- and MINUS-key, the chosen setting appears in the
display.
- 3 seconds after the last key operation (selection of the
setting) and within 16 seconds after activation of the heat-up
function, the symbol "A" (which stands for the heat-up
boost) appears on the display, in alternation with the chosen
setting.
- If a lower setting will be selected with the MINUS-key after
the "A" has appeared in the display, the automatic heat-up
function will be interrupted.
- By means of the PLUS-key a higher continuous setting can
be chosen, here the duration of the heat-up boost will be
automatically adapted to the actual selected setting.
- When the heat-up time is over, the selected (continuous)
setting will be indicated on the display.
Residual heat indicator
It is meant to indicate to the user that the glass ceramic has
a dangerous touch temperature in the circumference of a
cooking zone. The temperature will be determined following
a mathematical model and the remaining residual heat will
be indicated by means of "H" on the corresponding 7-
segmentdisplay. Heating-up and cooling down will be
calculated dependent on
· the selected setting („0" to „9")
· the ON/OFF time.
After switching-OFF the cooking zone the respective display
shows "H" until the assigned cooking zone temperature is
mathematically in a uncritical level. (≤ 60°C).
Automatic power OFF function (operating time limitation)
Dependent on the selected setting, every cooking zone will
be switched-OFF after a defined maximum operation time if
no operation of the assigned cooking zone follows within
this time period. Every change of the cooking zone condition
(by means of the PLUS-, MINUS- or BOOSTER key) puts
back the maximum operation time of this cooking zone to
the initial value of the operating time limitation.
Protection against unintended switching-ON
· If the electronic control realizes a continuous operation of
keys for approx. 10 seconds, it switches OFF automatically.
The control sends out an audible failure signal for 10
seconds, so that the user can remove the object which has
been mistakenly placed onto the operation surface. The
displays show the failure code " E R 0 3 " . If the failure
carries on for more than 10 seconds, only the code "E R 0 3
" will be displayed as long as the failure will be recognized
by the electronic control. If the cooking zone is in the "hot"
status, "H" will appear on the display in alteration with the
failure notice.
· If no cooking zone will be activated within 20 seconds after
switching-ON by means of the Power-key, the control
switches back from the ON-condition into the stand-by-
mode.
· When the control is switched- ON the ON/OFF-key has
priority over all other keys, so that the control can be
switched-OFF anytime, even in case of multiple or
continuous operation of keys.
· In the stand-by mode a continous operation will not be
signalized. However, before the electronic control can be
switched-ON again, it has to recognize that all keys are not
operated.
Key lock (child safety feature)
◊ Child safety feature:
Key lock:
After switching-ON the control the child safety feature can be
activated. To achieve this it is necessary to simultaneously
operate the front right cooking zone- select-key and the
MINUS-key and then press the front right cooking-zone-
select key again. There will be an "L", meaning LOCKED
(child safety feature against unintended switching-ON). If a
cooking zone is in the "hot" condition, "L" and "H" will be
displayed in alternation.
This course of operation has to take place within a period of
10 seconds, no other key than described above may be
operated. Otherwise the input will be interrupted because of
incompleteness, the cook top will not be locked then. The
electronic control remains in a locked condition until it gets
unlocked, even if the control has been switched-OFF and -ON
in the meantime. Also a reset of the control (after a voltage
drop) does not cancel the key lock.
Unlocking for cooking purposes:
To unlock and operate the control it is required to operate
the front right cooking- zone select- key and the MINUS-key
simultaneously. "L" (LOCKED) in the display extinguishes
and all cooking zones show "0" with a blinking dot. Should a
cooking zone be "hot", "H" is displayed instead of the static
"0". After switching- OFF the control, the child safety feature
is active again.
Cancelling the key lock:
After switching-ON the control the child safety feature can be
deactivated. Here it is necessary to simultaneously operate
the front right cooking-zone-select key and the MINUS-key
and then operate the MINUS-key alone. If all steps have been
carried out in the right order within 10 seconds the key lock
gets cancelled and the control is OFF. Otherwise the input
will be considered incomplete, the control remains locked
and switches-OFF after 20 seconds. After a renewed
