CONTROL SYSTEM FOR A DOMESTIC APPLIANCE

摘要

A control system (1) for controlling a heating element (6) for heating a fluid in an electrical appliance (2) is provided. The control system at least comprises an electrical network (4) adapted to supply power from a power main (28) to the heating element of the electrical appliance, at least one of an electric current measurement device (12) and an electric potential difference measurement device (22), a control unit (14) for determining a heating element input parameter value at least based on the measured current value and/or the measured voltage value and comparing said determined input parameter value with a predetermined heating element parameter value stored in the control unit. The control unit is further adapted to interrupt the power supply to the heating element in case the heating element input parameter value exceeds the predetermined parameter value to prevent uncontrolled heating of the heating element.
