Abstract
Abstract A system for cycling loads within a building to save energy is disclosed having a control apparatus for cycling the loads on and off according to a predetermined cycle rate, each load having an on time and off time within a cycle and wherein the control apparatus is responsive to a temperature sensor located within the building for resetting the off time of the load during each cycle.
