How the burners operate
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.
