cooking zone is "hot "0" is displayed instead of "H" . On all
other cooking zone displays the blinking dot extinguishes.
After selection of a cooking zone the setting can be
increased by continuously pressing the PLUS-key (5),
starting at step "1" it is increased by 1 step every 0,4
seconds. When setting "9" is reached the setting will not be
changed further (end stop).
If the selected cooking zone will be switched ON by
means of the MINUS key (4), the cooking zone starts at the
maximum setting "9" ("reverse switching-ON").
When the key is continuously operated, it decreases by
1 step every 0,4 seconds. When setting "0" is reached,
there will be no further setting changed (end stop). Only a
renewed operation of the MINUS (or PLUS) key changes the
setting.
Switching OFF an individual cooking zone
To switch off an individual cooking zone, the respective
cooking zone has to be selected with the cooking-zone-
select key (2). The selection is indicated with the static dot
(13) in the respective cooking zone display. If the control
recognizes that the PLUS (5) and the MINUS (4) key have
been activated simultaneously the setting of the selected
cooking zone will be put back to "0". Alternatively, the
MINUS-key can be used to count down the setting to "0".
If all cooking zones are at "0", all decimal points in the
cooking zone displays are blinking. If a cooking zone is
"hot", "H" will be displayed instead of "0".
Switching-OFF all cooking zones
Immediate switching-OFF of all cooking zones can be
achieved anytime by means of the ON/OFF key (1). 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
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
100 % ED for a
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.
