the upper left corner of the display. If only the internal circuit is to be switched
on, the external circuit can be switched off using the dual circuit button (3).
Press the dual circuit button (3) again to re-activate the external circuit and
the corresponding pilot light (11) will switch on.
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 Switch-off (Operating Time Limitation)
For each activated cooking zone a max. operating time is defined. The
max. operating time is depending on the selected cooking stage. After the
expiration of the max. operating time the cooking zone is automatically
switched off.
Each actuation of the cooking zone status (changing the cooking level etc.)
resets the count-down timer to the initial starting value.
Timer settings takes priority vs. operating time limitations for high cooking
stage setting.
Protection against unintentional activation
The electronic system cuts off automatically in case of an identified
permanent use of keys for about 10 seconds. The control unit releases an
audible signal for 10 sec of the malfunction (period: 1000 msec, 500 msec
ON) and the error code "E R 0 3" flashes on the display (0.5 s ON 0.5s OFF). If
the permanant actuation exceeds 10sec, alone the error code "ER 03" keeps
flashing as long as the malfunction occurs and is identified as such. In case
the cooking zone is at stage "hot" the [H] symbol alternates with the error
code (0.5 sec Symbol 0.5 sec "H").
Water sprinkled on the glass surface does not always lead to a key actuation
and cannot be surely detected. (After wiping the glass covering the keys, all
keys are ready for operation in no time).
If no cooking zone is activated within 20 sec after pressing POWER ON, the
control unit is reset to Off-mode (black displays).
Pause mode
Activating the Pause function:
While at least one cooking zone is working, the cooking zones can be switched
off by touching the "Pause" (4) key for more than 1 sec.
During the pause:
Timers already programmed are discontinued and remain in this condition
during the pause.
The pause mode can last for max. 10 min. If the status is not cancelled within
this period, the control unit switches off. The TC unit can be switched off via the
ON/OFF key at any time, a possible pause mode is, thus, aborted.
Terminating the Pause mode:
Touching Pause key together with any other one key within 10 sec causes a
re-establishment of the state prevailing prior to the pause mode. If no further
key is touched within 10 sec, the TC unit switches off.
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 PAUSE-key and then press the front right cooking-zo-
ne-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 co-
oking- zone select- key and the PAUSE-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 PAUSE-key and then operate the PAUSE-key alone. If all steps have
been carried out in the right order within 10 seconds the key lock gets cance-
lled and the control is OFF. Otherwise the input will be considered incomplete,
the control remains locked and switches-FF 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 co-
oking zone is in "hot" mode, "0" and "H" will be alternately displayed.
Acoustic Feedback (Buzzer)
The following activities occurring during operation of the TC unit are fed back
audibly via a buzzer:
- Short single tone for regular actuation of a key.
- Longer, intermittent tone for permanent use of keys over a longer period of
time (≥ 10 sec).
- Expiry of the timer.
Timer-function (optional)
The timer function is available in two types:
-Stand-alone-timer 1..99 min: Audible signal with timing. This function can
only be activated as long as no cooking zone is in operation (all stages = 0).
Is any cooking zone started with operation (level >0) than the stand alone
timer keeps in operation. If the timer shall be used to cut off a cooking zone
(see cooking zone timer) then the control must first be switched off (power
sensor) and switched on again.
-Cooking zone timer 1..99 min: This function can only be activated as long as
a cooking is active (stage < 0; display dot). Audible signal with timing, four
cooking zones to be cut off are freely programmable.
Setting a timer value:
By adjustment with the slider area.
Primarily the adjustment of the first digit takes place and thereafter the
adjustment of the second digit.
Within 10sec after the adjustment of the second digit the value might be reset.
(Illuminated display dot in the timer display and in case of a cooking zone
specific timer a blinking assigned LED).
In case of an active timer display the timer value may be set to [0] directly by
pressing [0] on the slider area (left side).
Switching of an active timer:
A timer can be switched of by setting its value to 0.
