Additional Details and Usage

The hob works on the principle of electromagnetic induction, generating heat directly in the bottom of the pan during contact with the hob. The Quick Start function allows the chosen temperature to be reached faster by working at maximum power until the right temperature is achieved.

The power booster option lets a zone operate at full power when very intense cooking is necessary. All ceramic hobs have a timer which automatically ends cooking after a preset time, and the time elapsed function shows how long the cooking zone has been in use.

After switching off, indication of residual heat shows which heating zones remain hot. When the temperature drops below 60 °C, the indicator goes out. Overheat protection automatically turns off the hob if the control unit overheats.

The Eco–Off energy–saving function shuts the zone down before the timer sounds, making use of residual heat in the pan. Child lock prevents the programme or cycle being accidentally changed, and protection against accidental start up avoids unintended operation.
