raise or lower the number of hours of operation from 0 to 9. When the minus (12) and plus (13) keys of
the clock programming system are kept pressed, the hours will be continuously changed.
The clock key (11) must be pressed again to indicate the number of minutes. Now the numbers on the
right of the decimal point will flash. Proceed the same as described for the hours to set the minutes.
The current setting can be reset at any time while the time is being programmed by pressing the minus
(12) and plus (13) keys of the clock programming simultaneously. A time equal to zero will deactivate
the timer of a burner. The clock key (11) must be pressed in order to confirm the time shown in the
display. Now only the displays of the cooking zones for which a timer has been activated will blink.
Pressing the clock key (11) will take you back to programming the timer in order to display the time
remaining until switch-off or in order to process the current settings. If no key is pressed for longer than
10 seconds during the programming process, the setting will automatically be discontinued and returned
to the main display. Changes to the settings of the selected cooking zone burner are not deleted and the
corresponding timer remains activated.
The timer can be programmed when the burner is switched off and when it is ignited. Timing starts as
soon as the time that has been set is confirmed. Once the time has lapsed the burner is switched off with
the timer and at the same time a buzzer sounds for 30 seconds (the acoustic alarm can be switched off
by pressing the clock key (11)).
When a cooking zone burner is switched off by a user the corresponding timer is also deactivated.
