Miele KM 5820 - Manual (Page 13)

One-zone burners use one heating
strip; two-zone burners and grill zones
have two heating strips. Depending on
the model, the heating strips may be
separated by a ring.
Each burner has overheating protection
(internal temperature limiter) feature to
prevent the ceramic glass from
overheating (see "Overheat protection").
When a power level is set, the heat
element turns on and the heating strip
is visible through the ceramic glass.
The power setting determines how hot
the burner will get, and is electronically
regulated. This means that the burner
will switch on and off as needed to
maintain the selected power level.
