A self optimizing device for controlling a heating unit in a manner so as to improve the energy efficiency of the heating unit using an autocalibration processor . The heating unit employs a heating medium that is heated by the heating unit and which transfers the heat into an ambient atmosphere outside of the heating unit. T he heating unit has an on-state initiated when a characteristic of the heating medium representative of the heating capacity of the medium decreases below a minimum level, and a n off-state initiated when the characteristic of the heating medium reaches a maximum level. The controller includes an input element, an output element, a time-measurin g element, and a processor. The input element receives a signal from a sensor, the sign al indicating the heating medium characteristic representative of the heating capacity of the heating medium. The output element signals the heating unit to begin its on- state. The time-measuring element measures an off-time, the off-time being the length o f time from initiation of the off-state of the heating unit until the characteristi c of the heating medium decreases below the minimum level. The processor determines a delay time and for signaling the heating unit to delay initiation of the on-state by th e delay time amount, theextension of the off-time resulting in an energy savings over an undelayed initiation. The processor further comprising an autocalibration processor fo r determining a delay time that results in optimum energy savings.
