How the cooking zones work
19
Single circle cooking zones have one
heating element, whilst double circle
cooking zones and extended zones
have two. Depending on 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 becom-
ing too hot (see "Overheating protec-
tion").
When a power level is selected, the
heat switches on and the element can
be seen through the ceramic surface.
The temperature of the cooking zones
depends on the power level selected,
and is electronically regulated. This
controls the "timing" of the cooking
zone by switching the element on and
off.
