Abstract
A pump control system incorporates a programmed processor and responds to input from multiple floats. The programmed processor can respond to detected float failures in real time by reassigning control, lag, or lead functions from a failing float to one of the remaining functioning floats. Pump alternating functionality can be provided if any two of a plurality of four or more floats continue to function as expected.
