  • the input to the control circuit 24 generates a signal input 44 to the power level symbol set 36 to indicate that a Power level is to be set.
  • a signal can also be a visible indication effect such as by one or more display segments 44 that are illuminated, for example in a pulsed light display, which indicates that that a power level must be set to close the rear left hob activated.
  • sequential actuation of a symbol segment 43 on the ring 38 in the Power level symbol set 36 can be the intermittent pulse operation of the illuminated Segments are ended.
  • the input of a switch 42 to the control unit 24 also generates a response in the control circuit to change the display 34 to show the selected power level, for example an LED display of number 5, with the ring segment selected on the second set 36 43 matches. If the rear left symbol 28 or the symbol ring 38 from If the user is operated again, the control circuit 24 deactivates the rear left hotplate, changes the display 34 again on a base value display such as 0 and can again on the display 44 on the symbol ring 38 cause the pulse lighting.
  • the power level can be restored once a sequential operation of a symbol 28 and a symbol 38 of the first set 26 or of the second set 36 carried out within a predetermined time has been. After a predetermined time, one or both of the displays 34 and 44 be deactivated if there is no power at the selected hotplate.
  • Switches which signals the control circuit 24, both the rear right as well as the front right heating element to activate for operation, and the associated Display 34 together with the same power level. More like that A time-sequential operation of the power stage ring 38 signals via the associated switch or switch 42 that the control circuit 24 an indication of the power level to be transmitted to both the right rear and the right front hob Receives signal. Accordingly, the displays 34 show on the right front and right rear symbol 28 the same information according to the selected one Segment 43 of the symbol ring 38.
  • 36 additional symbols can be present on a power level set, to represent several power levels that are available for the hotplates. So the symbol WARM 50 can be used to identify a switch by whose actuation the control circuit 24 a low power level for the on the first symbol set 26 selected hotplate switches on. Through the control circuit 24, for example Power for the low power level will be triggered when the sequential operation of the Symbols 50 from the second symbol set 36 is done.
  • the signal can measure the heating power in one Limit the specified period, for example to 2 seconds of power consumption for a period of 50 seconds so that the heating element on the hob is one generates very low heating heat.
