Abstract

The invention disclosed herein is a temperature dependent duty cycler control system which provides a duty cycle off time locus responsive to a sensed temperature and is characterized by two selectable off time periods which are connected by slope controllable ramping functions. The system also includes means for coordinating operation of several heating and/or cooling units by making real time determinations of the most efficient average number of units which should be running at a given time and by maintaining a priority order of rotation of the units available to be shed.
