1. A frypan control system for controlling a supply of electrical power to a heating element associated with said frypan, said control system being adapted to control said supply of power in a first mode for simmering and in a second mode for cooking, comprising:

  • sensing means arranged in a heat conducting relationship with said heating element for sensing the temperature of said heating element;

    setting means for setting the required operating temperature for said frypan;

    microprocessor means receiving output from said sensing means and said setting means for providing in said first mode a control signal comprising control periods each having a first duration and a duty cycle which is related to the difference between the temperature of said setting means and the temperature of said sensing means, and in said second mode a control signal comprising control periods each having a second duration, said second duration being greater than said first duration; and

    switching means responsive to said control signals for switching said supply of electrical power to said heating element for control periods having said first duration and duty cycle in said first mode and for control periods having said second duration in said second mode.
