How The Cooking Zones Work - Miele KM 520 Operating And Installation Manual

Single circle cooking zones have one
heating element, whilst double circle
(vario) cooking zones and extended
zones have two. Depending on the
model, the heating elements may be
separated by an isolating ring.
Each cooking zone has overheating
protection (a temperature limiter), which
stops the ceramic surface from
becoming too hot (see "Overheating
protection").
When a power level is selected, the
heat switches on and the element can
be seen through the ceramic surface.
The heat output of the cooking zones
depends on the power level selected,
and is electronically regulated. This
controls the "timing" of a cooking zone,
switching the element on and off.
