OPERATING PRINCIPLE (Fig. 1)

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.

Installation

All operations relative to installation (electric connection) should be carried out by skilled personnel in conformity with the rules in force.

As for the specific instructions see part pertaining to installer.

Functionality Slider TC:

Slider: sensor technology of the novel Slider TC allows as well an adjustment of the cooking levels (1 - 9) as the timer value (1-99) by touching and pulling the finger over the designated area. Pulling to the right is increasing and to the left is decreasing accordant value.

Moreover a direct selection of the designated value is also possible on the slider area.

ON/OFF Touch Control

After connecting to the mains the TC unit takes 1 second to prepare for operation. After a reset all displays and LEDs flashes up for 1 second. After 1 second all displays and LEDs are switched off again.

The TC unit may now be switched ON by pressing the ON/OFF key "1". Displays show a steady "0". Possible optic warnings for hot cooking zones [H] are displayed in alternation with [O] and the synchronously display dot. The display dots on the cook top displays flashes up every second (0.5 sec.off, 0.5 sec.on). Electronics remains activated for 20 seconds. If there is no cooking level or timer selection done in this period the electronics automatically resets to the Off-mode by releasing a signal tone.

The TC may only be switched on by pressing the power key as sole input In case of another key is pressed (single or in parallel with the power key), the

control unit is not switched on.

In case of an active "Child Lock Function" when switching POWER ON, all cooking zone displays show "L" for LOCKED. Possible optic warnings for hot cooking zones [H] are displayed in alternation with [L] (H-ON= 0.5 sec; L-ON = 1.5sec). By pressing the ON/OFF key "1" of the control unit in ON-Mode, the Touch Control may be switched off at any time. This is also applicable for locked control units (active child lock). The ON/OFF key takes always priority with the POWER-OFF function.

Automatic Switch Off

The TC switches from Power ON to OFF after 20 sec, provided that no cooking zone is activated or a select key is pressed during that time.

In case of a selected cooking zone (with cooking stage is "0") this Auto Power off time is composed of a 10 sec deselection time and 10 sec Power off time.

ON/OFF Cooking Zone

In case of On-state of the TC a cooking zone may be selected by touching the dedicated display (Select-Sensors "8"). The respective display changes to a steady display dot and "0" instead of "H" in case of a hot cooking zone. On all other cooking zone displays the dot expires.

That followed a cooking level may be set by using the Slider area. Thus switches the respective cooking zone on. End stops are "9" (right side) and "0" (left side).

First place the pan in the chosen cooking zone. If the pan is not present the system cannot be switched on the correspondent zone and the following symbol will be displayed:

Switching Off a single cooking zone:

A single cooking zone may be switched off by selecting and setting cooking level to [0]. In case of an optic warning for hot cooking zones [H] this is displayed in alternation with [0] and the synchronously display dot.

After the TC is switched Off the display remains black respectively [H] is displayed for an optic warning for hot cooking zone.

Switching Off all cooking zones:

Immediately switching off all cooking zones is always possible by using the ON/OFF key.[H] possibly appears on all hot cooking zones. All other cooking zone displays remain black.

Power Stages

The power of the cooking zone is adjustable in 9 different stages; the respective stage is displayed ([1]) to [9]) via LED seven-segment-displays. In case more power is required, select the boost level (^ ^ )

Booster function

After selection of a respective cooking zone, the booster function can be selected directly via the power function key (3). By means of this function certain cooking zones are enabled to receive power over the nominal. If the desired cooking zone has the capacity to activate the booster, the display shows a "P" symbol. 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.

Control of multiple circuits

When a dual cooking zone is activated, the two circuits are switched on at the same time. Activation of the external circuit is indicated by a pilot light (11) in

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^n
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^)

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 "ER 0 3" flashes on the display (0.5 s ON 0.5s OFF). If the permanent 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-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 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 cancelled 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 cooking 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.

A stand alone timer can be switched off by a double actuation of the power key "1".

Timer Stand-Alone:

If the control unit is switched on (all cooking zone displays show [0]), the stand-alone timer may be activated by pressing the timer select key. The timer display show "00". The decimal dot on the timer display flashes. The timer is cut off after 10 sec (black display) if no further settings are made. In case of a timer value is set with no activation of a cooking zone within 10sec, the cooking zone displays are cut off (interposing relays are also cut off). Possible optic warnings for hot cooking zones [H] are displayed permanently As long as the timer is selected (display dot flashes for 10 sec) it can be set. The setting range is 0 -99 minutes in single steps; by Slider area.

Directly after the timer value is set, count down starts with the last set value. The timer is deselected automatically after 10 sec and the timer display indicates the timer value. After expiring of the set time an acoustic signal is given and the timer display flashes 00^ .

The acoustic signal is terminated

-after 2 min and/or

-by actuating any key.

Thereafter timer display stops blinking and extinguishes. Possible optic warnings for hot cooking zones [H] are displayed permanently.

By pressing the ON/OFF key "1", the control unit may be switched from "purely timer operation" to cooking zone at any time -with or without an activated Stand-Alone timer-.

Switching back to TC active mode with an active Stand-Alone timer the timer is selected first (decimal dot on timer display flashes). After a cooking zone is selected, the decimal dot disappears from the timer display and a steady decimal dot on the cooking zone display flashes on. When switching off the control unit by ON/OFF key "1", the Stand-Alone timer - if still in operation -is also switched off.

Cooking zone specific timer programming

Switching on the TC enables timer setting for dedicated cooking zones.

By actuating a cooking zone (cooking zone stage >0 ) followed by selecting the timer display (within 10 sec) a timer value may be assigned to the cooking zone as a cut-off function. The LED around the timer "9" indicates which cooking zone the timer had been activated for. As soon as the timer is selected the according LED is blinking and the dot in the timer display is flashing permanently. In case of a cooking zone is selected thereafter, the dot extinguishes and the LED stops blinking.

When switching from one cooking zone to another, the timer display indicates the current timer value of the respective cooking zone. Timer settings of other cooking zones stay active.

Further setting is like with the stand-alone timer.

In case of more than one active timer the display indicates the lowest timer value (after 10s deselection time).

After expiring of the set time an acoustic signal is given and the timer display flashes "00". The related timer LED is blinking synchronously. The programmed cooking zone is cut-off, a permanent "0" is displayed and the cooking zone is selected automatically. After 10 sec (deselection time) a permanent "H" is displayed on a hot cooking zone. Otherwise, the symbol "0" is indicated.

The acoustic signal and the blinking of the cooking zone timer Led is terminated

• after 2 min and/or

• by actuating any key.

Thereafter timer display stops extinguishes and the cooking zone stays unselected.

Behaviour of the cooking zone specific timer is similar to the stand alone timer.

In case of a timer is programmed for a cooking zone the operating time limitation is dependent of the timer value and not of the standard table value.

Cooking vessels (Fig. 3)

• 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 the same diameter as zones 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 10cm .
• 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, alluminium, copper or non-magnetic (austenitic) stainlesssteel vessels.

Maintenance (Fig. 4)

By means of a scraper immediately remove any aluminium foil bits, food spills, grease splashes, sugar marks and other high sugarcontent food from the surface in order to avoid damaging the hob. Subsequently clean the surface with some towel and appropriate product, 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.
