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