ABSTRACT:
A step controller for a water heater includes a plurality of individual electrical elements to maintain a predetermined minimum temperature in accordance with a sensed temperature signal and a preset desired temperature signal in combination with a dead band signal. The heating elements are turned "on" and "off" in a random sequence whenever a change is required, and in accordance with a binomial distribution so as to substantially equalize the operating period of the heating elements. The controller includes a microprocessor unit to periodically sense the signals of a sensor and a preset potentiometer, and also operates to store the on-off status of the heating elements, each of which is assigned a binary load indentifying number. The microprocessor includes a psuedo-random binary number generator for generating the load identifying numbers. The generator generates numbers in a pattern which closely approximates a binomial distribution and therefore a statistical "random" selection which over any reasonable selection period, each of the numbers will be created on equal number of times. Upon a demand to increase or decrease the number of "on" heating elements, a random code number is generated, and if such load is available it is actuated. If not, a new code is generated until an anvalable heating element is located and it is then properly operated.
