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.
In the cooking zone located on the front left, when selecting
the power level 9 and after 30 minutes operating, the power
will decrease slightly for safety reasons. In case more power is
required, select the boost level (“P”)
Boost function
After selection of a respective cooking zone, the boost function
can be activated by selecting the power level 9 and then pressing
PLUS (3) button . By means of this function certain cooking
zones are enabled to receive power over the nominal (the number
of boostable cooking zone depends on the power available on a
partial modules which is to be lees than total hob power ). If the
desired cooking zone has the capacity to activate the booster,
the display shows a “P“ symbol. In case the available power is
not enough the cooking stage display flashes for 3 seconds on
the cooking zone which needs to be reduced and which requires
automatic adjustment.
The boosting time is limited to 5 min to protect cooking utensils.
After the booster is switched off automatically, the cooking zone
continues operation on power level “9”. The booster can be
reactivated after some minutes.
In case that the pan is removed from the cooking zone during
boosting, the boosting function remains active and boosting
time continues.
The power management is based on on the principle that the
last entry is requested by the induction as top priority. That
means that previous actions and settings also made for the other
cooking zones are reversed automatically, if necessary.
- If induction identifies the necessity of reducing power at a
cooking zone, the selected cooking stage flashes on that
cooking zone providing a correction period of 3 sec before the
power is reduced automatically to a minimum cooking stage.
- If the setting is adjusted within the correction period, the power
management checks the settings again. Should a new setting lead
to further power reduction, the correction period starts again.
- If no automatic correction needs being made to the cooking
zone setting, the flashing stops immediately and the original
value remains as a steady display indication. Should the
situation change again on the power reduced cooking zone, no
automatic power increase is effected.
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-segment
display.
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- 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 switching-ON by means of the ON/OFF key all
displays show „0“, the display dots are blinking and the control
is ready for cooking. If a cooking zone is in “hot” mode, “0” and
“H” will be alternately displayed.
Audible signal (buzzer)
