Switched off, the hob presents an entirely black surface. No cooking zone or control panel graphic is visible, only the switch on Touch-Symbol in front and the brand logo. No hob graphic disturbs the purist design of the kitchen. Switched on, the user interface and the cooking zones become visible as an illuminated graphic. The cooking zone temperatures are individually set with a circular movement of the finger on each of the operating zones and shown in numbers and with an LED circle. The hobs are available with a metal frame, facet glass and built-in flush.
