• wherein the display control unit (4) is configured to:
• transmit control signals to the touch-sensitive display (3), to change the first graphical representation into a second graphical representation, in response to a touch on the symbol (V1, V2) by a touching means, wherein the number of symbols to be displayed in the second graphical representation is reduced with respect to the number of symbols displayed in the first graphical representation;
• wherein the touch-sensitive display (3) is configured to:
• display a value range indication (7) in the second graphical representation in order to indicate which position at the touch-sensitive display (3) is associated with a certain setting value, and is further configured to:
• display information regarding a change of a setting value of the heating elements (6) associated with the touched symbol (V1) when said touching means is dragged from a first position to a second position at the touch-sensitive display (3);
• and
• wherein the display control unit (4) is configured to:
• change the graphical representation at the touch-sensitive display (3) from the second graphical representation to a third graphical representation in response to lifting of the touching means from the touch-sensitive display (3), and is further configured to:
• forward to the appliance control unit (5) a setting value associated with the second position in response to lifting of the touching means from the touch-sensitive display (3).
