Abstract
The present disclosure is directed toward a control system for controlling a heater system. The control system includes a plurality of zone control circuits, at least two auxiliary controllers, and a primary controller. The zone control circuits are operable to provide power to a plurality of heater zones of the heater system and to sense performance characteristics of the zones. The auxiliary controllers are coupled to the plurality of zone control circuits to control power to the plurality of zones and to monitor operation of the heater zones based on the performance characteristics. The primary controller is coupled to the auxiliary controllers and is configured to provide an operation set-point for each of the heater zones based on the performance characteristics. The auxiliary controllers operate the zone control circuits to supply power to the heater system based on the operation set-point.
