Abstract

A measuring and control circuit for measuring the voltage of an alternating current source and controlling the operations of an associated load. A memory associated with the microprocessor is programmed to provide information representative of voltage levels associated with various modes of operation associated with the load. Tested levels are compared with programmed voltage levels to determine needed load control.
