ABSTRACT:
A control system is provided in which a plurality of independent control elements are each capable of generating a random value and determining a time delay as a function of that random value. Each of the control elements accesses the magnitude of a sensed parameter and responds to that magnitude. When correction of the sensed parameter is required, each independent control element senses the need for a correction and delays by an amount of time determined randomly and independent from all other control elements. After the randomly determined time delay has elapsed for each control element, that control element again accesses the magnitude of the sensed parameter and, if correction is still required, changes the connection status of an associated switch. In a preferred embodiment of the present invention, the control element interrogates the status of its associated switch to determine if actuation would benefit the correction of the magnitude of the sensed parameter.
