[. . . ] The appliance data plate, with technical specifications, is positioned at a visible point under the bottom and is also enclosed with this manual. Be sure to avoid the following actions: do not touch cooking zones that are heated. Do not place aluminium foil or plastic containers (the protective films are not suitable for this hob) If there is a drawer under the hob, it is advisable not to keep inflammable objects or spray cans in it. If there are breaks, cracks or splits in the ceramic glass, there is a risk of short-circuiting; If the cooking zone overheats but the display does not work or If the hob switches off by itself: Immediately switch off the appliance and contact the technical assistance service. [. . . ] By pressing the key "+" you can select a power level and the zone will start heating up. If the cooking zone is selected using the "-" key, the initial level is 9 (the highest level available). A cooking zone can be switched off in the following way: By pressing the + and the - keys of the desired cooking zone simultaneously By selecting cooking zone 0 for the desired cooking zone by pressing the - key. All cooking zones can be switched off immediately, at any moment, by pressing the power button. When the automatic heating function has been activated, the power of the cooking zone reaches 100% for an established heating time, which depends on the selected power level. At the end of this heating time, the touch control returns to the pre-selected power level. Procedure to start automatic heating: - The control unit is switched on and a cooking zone is selected; - After setting cooking stage "9" automatic heating is activated by pressing the "+" key again. Once the parboiling boost has ended, only the selected cooking stage is indicated on the display. Using the "minus" key you can de-activate the function at any time. Based on the power level, each cooking zone is shut off after a maximum preset time if no operations are performed. Each operation with the cooking zone (using the PLUS or MINUS keys, or the dual circuit in the zone where present) resets the maximum operation time to its initial value. When the control is on, the ON/OFF key has priority over all other keys, so that the control can be shut off at any time, even in the event of multiple or continuous activation of keys. In standby mode, continuous activation of keys will not have any effect. However, before the electronic control can be turned back on, it must recognize that no key is activated. Otherwise, to lock press the cooking zone select key and the minus key simultaneously followed by pressing the cooking zone select key again. All displays show an L for LOCKED (= child lock against unintentional activation). This operational procedure must take place within 10sec and no other key than the one described above may be pressed. The electronics remains in a locked condition until its released, even if the control until is switched off and on again in the meantime. For release, press the cooking zone select and the minus key simultaneously. L for LOCKED disappears from the display and all cooking zones display 0 with a flashing dot. For de-active the lock function definitely, press the cooking zone select key and the minus key simultaneously followed by pressing only the minus key again. After carrying out all steps in the correct order and within a period of 10 sec, the locking is cancelled and the control unit is in a STAND-BY mode.

Never use abrasive sponges or irritating chemical detergents as they might cause damage to glass. Any spilt food like sugar and other cause damage the hob, it must be removed immediately with the scaper. The following damages will not affect the correct functioning or the stability of the ceramic glass: Scratches due to salt, sugar or sand grains or rough pan bottoms; The formation of gelatinous residues Alteration glass colour from pan use or decoloration due to using unsuitable detergent Overheating of the induction coils Permanent use of keys; Control unit cuts off after 10 sec Error on filter board / Water or cooking utensils on the glass above the control unit Controller flash defect; check sum not correct 5V short circuit with power unit 12V on power unit too low temperature sensor at cooling body defect mains synchronous impulse incorrect Cooling down necessary Cleaning of the operational surface Exchange filter board Sub LIN error between filter and power unit Control switches off after 10 sec Control switches off after 60sec at the latest Short-circuit in the 5V or earthed control relay Short-circuit or disconnected pan sensor or power supply µC- faulty Standard algorithm reaches limit when overheated.
