Key lock (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
cookingzone - select-key (+) 1 and the (-)-key
2 and then press the front right cooking-zone-
selectkey (+) 1 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 cooktop 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-zoneselect-
key (+) 1 and the (-) 2-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.
