MULTI-ZONE HEATING SYSTEM

摘要

A heating system is disclosed including a cabinet having walls defining an interior heating chamber. Sensors are attached to an exterior surface of the walls. Heating pad subassemblies are attached to the exterior surface of the walls with each heating pad subassemblies located adjacent a corresponding sensor. The heating pad subassemblies include a pad having an attachment face coupled to the exterior surface of the walls and a heating element coupled to the pad. A controller is in electrical communication with the heating elements and the sensors. This controller is configured to independently monitor temperate measurements from each of the sensors and to independently control each of the heating elements. The heating pad subassemblies are positionable on the exterior side of the plurality of walls and the heating system compensates for load variations across the interior heating chamber.
