Abstract
A process is provided for output control and limitation in a heating surface made from glass ceramic or a comparable material, especially a glass ceramic cooking surface. In a heating surface, in which the individual heating zones are each heated with several heating elements, switchable and controllable independent of one another, it is provided according to the invention that all points of the areas essential for a stress case, especially local overheating, are detected by several temperature sensors, independent of one another, which are placed in the area of the heating zone, to switch and to control the individual heating elements, independent of one another so that the output distribution in the heating zone area is largely matched to the locally varying removal of heat.
