Abstract
An oven control system and user interface are provided for setting a target temperature for different zones within an oven. A thermocouple is provided in each zone within the oven to monitor the realized temperature within the specific zone of the oven. A plurality of different heater elements are also provided within each zone of the oven. The control system enables a user to easily and efficiently select a target setpoint temperature for each zone within the oven, or for the chair rail, or the sag rails. For the case of the oven, the setpoint provides a virtual heat setpoint for the complete oven section which is then realized by controllably regulating operation of the various unique heating elements within that zone of the oven to realize the desired setpoint temperature within that specific zone of the oven. Such control is realized by way of proportional integral differential (PID) loops that are adjusted for each of the heater elements in order to realize the desired virtual heat setpoint for the specific zone of the oven.
