Abstract
Temperature of a heating device is controlled by a microprocessor in an electrical circuit which electrically communicates temperature control signals to the heating device. The control signals are generated from a predetermined compilation of data stored in the electrical circuit or from external data which can be entered and used to control the temperature in the heating device to a selectable value at a rapid rate or to achieve one or more temperatures at selected rates. The external data entry and control is provided by a human-electronic interface.
