ABSTRACT:
A control is provided for switching on and off two heating devices of a hob forming a hotplate. In cyclic manner the continuous energy or power generation level can be adjusted by an energy control device. A temperature limiter monitors a maximum temperature via the first heating device, but not via the second heating device. The energy control device controls the first heating device directly or switches the same. The temperature limiter trips a power relay in order to switch the second heating device simultaneously with the first heating device.
