OPERATION
Operating Principle - Fig. 4
It exploits the electromagnetic properties of most cooking
vessels.
The coil (inductor) which produces the electromagnetic field is
operated and controlled by the electronic circuit.
The heat is transmitted to food by the cooking vessel itself.
The cooking process takes place as described below:
- loss of heat is minimum (high efficiency)
- the system stops automatically when the vessel is
removed or even just lifted from the hob the
electronic circuit guarantees maximum flexibility and
fine adjustments.
Use
First place the pan in the chosen cooking zone. If the pan is not present the system cannot be switched
on.
Switching the Touch Control On/Off
The electronic Touch Control is activated by means of the ON/OFF button and switches from the
OFF mode to the Stand-by mode. To do so it is necessary to press the ON/OFF button for 1 second.
A short Beep will be heard. When in stand-by, '0' is displayed on the display of the cooking zone. This
display may go into background due to a residual heat or error signal.
If a cooking zone is activated during the stand-by time (10 sec.), the control switches over to the On
mode.
If no introduction is made within the 10 sec., the control automatically switches to OFF with a short
beep.
The electronics can be switched to the OFF mode at any time during the ON mode or the Stand-by
mode by pressing the ON/OFF button. The Off function has priority when operating, meaning that the
control switches off even by activating several buttons at the same time.
Switching on a Cooking Zone
When in the Stand-by or On mode, a cooking zone can be switched on by means of the Plus/Minus
button, as long as the cooking zone is not in the timer programming mode at that moment.
If starting with the '+' button, the cooking level changes from '0' to '4'. If starting with the '-' button, the
cooking level changes from '0' to '9'.

Service Manual UK English
Switching Off a Cooking Zone
a) Pressing the '+' and '-' buttons of the desired cooking zone at the same time.
b) Selecting cooking level '0' of the desired cooking zone with the '-' button.
If the last cooking zone is switched off, the control switches to the OFF mode after 10 seconds if
nothing else is switched on.
All cooking zones are switched off immediately by pressing the ON/OFF button.
Cooking & Power Levels
The cooking and power levels of the cooking zones are shown on the display with 7 allotted segments.
In accordance with standards, the power levels are displayed with numbers from '1' to '9'.
Residual Heat Indicator
Indicates to the user that the glass is at a dangerous temperature if in contact with the area over the
cooking zone. The temperature is determined by means of a mathematical model and possible
residual heat is indicated by 'H' on the corresponding 7 segment display.
Heating and cooling are calculated based on:
- The selected power level (from '0' to '9');
- The relay activation time after the cooking zone has been switched off.
The corresponding display shows 'H' until the zone temperature drops below the critical level
(< 60 °C) according to the mathematical model.
Timer Function
The Timer function can be used as a cooking zone timer or independent alarm but never for both
functions. The two 7 segment displays of the respective cooking zones are used to view the remaining
time in minutes up until the timer alarm is activated.
Timer Selection
- To program a timer, the touch control must be in the Stand-by or On mode.
- The timer button is pressed in order to select a timer function for the cooking zone.
- LED 8 signals the timer programming by means of the +/- buttons. The flashing timer LED signals
that the 7 segment display value refers to the timer and can be modified. When a timer continues
to function in the OFF mode, the timer LED remains on. This indicates that the value on the
display is related to the timer, but cannot be directly modified at that particular moment; to do so,
the control must be reactivated.
- The activation of the timer button depends on the conditions of the previously set function:
a) The cooking zone corresponding to the timer is on (cooking level > 0): The timer is
programmed in reference to the cooking zone; the cooking zone automatically switches off
when reset; an independent timer cannot be selected. The cooking level setting is accessed
when the timer button is pressed again.
b) The cooking zone corresponding to the timer is off (cooking level = 0): The timer is
independently programmed and continues to function even in OFF. The cooking zone cannot
be activated until the timer is functioning.
12 of 17
Service Manual UK English
Setting of the Timer Value
- Following the selection of the time, the related LED flashes as described above. The countdown
time of the desired timer can be set by means of the +/- buttons.
- Starting with the plus button, the first value displayed is '01' and progressively increases from 1 to a
maximum value of '99' (upper limit).
- Starting with the minus button, the value displayed on the indication is “30” and diminishes to “01”
(first lower limit). When this value is reached, an acoustic signal is emitted. By pressing the minus
button again, the display “00” will not be modified (second lower limit).
- Setting can be performed by permanently pressing the plus or minus buttons or by intermittently
pressing them (selection: press button, release, press button, release, etc.).
- If the button is permanently pressed, the regulation speed automatically accelerates, meaning that
the time between one step and the next is reduced, until the button is released.
- If the Plus or Minus buttons are not pressed within 10 seconds (parameter), after having selected
the timer of the current cooking zone (the display remains on '00'), the indication and allocation of
the +/- buttons automatically switch to the cooking zone.
- When a timer is used as an alarm, the indication and allocation of the buttons does not switch to the
cooking zone, being that this cannot be activated.
- The timer normally starts in countdown, if programmed with two values that are not 0.
For example: the timer starts when the Plus button is released after the timer value has been set at
'01'.
- The timer settings have priority over the delimitation of the operating time if high cooking levels
have been set.
- If only one alarm has been programmed, the control remains at first in the stand-by mode (no other
cooking zone is on).
If no other new values are introduced, the TC behaves as described above and switches to the OFF
mode.
Timer Laps/Timer Alarm & Confirmation
- The last 10 seconds before the timer lapses are displayed (countdown up to alarm).
- Once the set time of the timer has lapsed, the timer alarm is activated and the assigned cooking
zone is switched off.
- The display and the selected timer LED flash alternating the cooking level from '00' to 'H', if there is
residual heat.
- The warning alarm lasts for at least 2 minutes if the user does not switch it off before.
- The alarm signal switches off after the 2 minutes is up or if any button is pushed. The buzzer and
the timer control light are switched off.
Timer Off /Modification of the Timer Setting
- The timer settings can be modified in the Stand-by or On mode at any time after the selection has
been made by pressing the Plus or Minus buttons.
- The timer can be switched off, setting it to value '00', by pressing the Minus button or by pressing
the Plus and Minus buttons together.

Key Lock (Child Safety)
Locking/Unlocking of the Key Lock
The keypad is blocked when the Key Lock button is pressed in the Stand-by or On mode; the Key-Lock
LED '9' lights permanently.
The control continues to operate in the previously set mode but can no longer be controlled by other
buttons, except by the Key-Lock button or the ON/OFF button.
Switching off with the ON/OFF button is also possible when locked. The Key-lock button LED switches
off when the Touch control and Key-Lock function are switched off. The LED lights again if reactivated
(within 10 seconds) until it is deactivated by pressing the Key-Lock button once again. The activation/
deactivation of the Key-Lock function is not possible in the OFF mode.
Unlocking/Deactivation of the Key Lock
The keypad is unlocked and the Key-Lock LED is switched off when the Key-Lock button is pressed
again in the Stand-by or On mode. All sensor buttons can once again be activated.
Automatic Heating (or 'Heatup' Function)
This function facilitates cooking. You don’t have to be there permanently during cooking. The hob heats
up automatically to full power and then returns to the selected level after a certain time (see Table).
Activating Automatic Heating
1. Press the selection button for the desired cooking
area.
2. Select power level 9 with the Minus button, then use
the Plus button to select level 'A' '9'. Afterwards set
the desired level for continuation of cooking with the
Minus button, e.g. level 6. The display will show
alternatively 'A' and '6' during the 'automatic heating'
function.
Example: Select power level 9 and activate the
automatic heating function with the Plus button
(display 9). Then set level 6 for continuation of cooking with the Minus button. With these settings
the hob will be heated for 2.5 min. at level 9, the display will alternate 'A' and '6' and will then return
to continuation cooking level 6.
Precautions
- in case you detect a crack, however small, in the hob surface, immediately disconnect the power
supply - when the hob is in use keep all magnetizable objects away (credit cards, floppy disks,
calculators and so on) - do not use any aluminium foil or place any foodstuffs wrapped in aluminium
foil directly on the hob.
- do not place any metal objects such as knives, forks, spoons and lids on the hob surface as they
will heat up - when cooking in a nonstick pan without seasoning, do not exceed 1-2 minutes
pre-heating time.
- when cooking food that may easily stick, start at a low power output level and then slowly increase
while regularly stirring.
- after cooking is finished, switch off using the control provided (turn down to '0'), and do not rely on
the pan sensor.

Cooking Vessels (Fig. 5)
- a magnet attracting vessel may be a suitable vessel
for induction cooking.
- prefer vessels which are especially declared to be
suitable for induction cooking.
- flat and thick bottomed vessels.
- a vessel with a 20 cm diameter ensures the
maximum exploitation of power,
- a smaller vessel reduces power exploitation, but does not cause any energy loss. We would
anyhow not recommend the use of vessels with diameters smaller than 10 cm.
- stainless-steel vessels with multi layer or ferritic stainless-steel bottoms when specifically suited for
induction cooking.
- cast iron preferably enamel bottomed vessels to avoid scratching the pyroceram surface.
- we do not recommend the use of any glass, ceramic, earthenware, aluminium, copper or
non-magnetic (austenitic) stainless-steel vessels.
Maintenance - Fig. 6
By means of a scraper immediately remove any aluminium foil
bits, food spills, grease splashes, sugar marks and other high
sugar content food from the surface in order to avoid damaging
the hob.
Subsequently clean the surface with some paper towel and
SIDOL or STANFIX, rinse with water and dry by means of a
clean cloth.
Under no circumstance should sponges or abrasive cloths be used; also avoid using aggressive
chemical detergents such as oven sprays and spot removers.

Service Manual UK English
The detection and prioitisation of most errors occurring with a cooking zone is carried out by the
induction sub-assembly. This is also responsible for the lag time of an error. Adding to this, the
communication period via LIN Bus is to be taken into account until the error is eventually indicated on
the TC. Most error numbers may have different cause, which is absolutely desired, as the indicated
error code is to provide a clue about which part of the entire system need to be replaced to tackle the
problem.
INDUCTION HEATERS
The two EGO combined heaters used in this appliance are ready to be installed components.
Combining four or two induction coils each with a separate frequency converter, ventilation is supplied
via a built in fan in the base of the heater.
The induction coil on the underside of the ceramic glass is energised by the frequency converter that
converts mains power into higher frequency alternating current.
This generates an electromagnetic alternating field that penetrates the glass ceramic panel and
induces a heat generating eddy current into the base of the pan on the glass.
Removing the pan automatically switches off the cooking zone.
There is also a temperature sensor which will switch off the cooking zone if the contents boil dry.
