<p>OVEN ELEMENT CONTROLLER A controller (250) for controlling heating elements (210, 220, 230) within a chamber (200) is disclosed. A variable energy controller (211, 221, 231) associate with each heating element (210, 220, 230) is provided. Each variable energy controller (211, 221, 231) receives a setting of an amount of energy to be supplied to the associated heating element (210, 220, 230), and controls the amount of energy supplied to the associated heating element (210, 220, 230) based upon the setting. A temperature sensor is provided within the chamber (200). A temperature controller (241) switches the energy supplied by the variable energy controllers (211, 221, 231) based upon the temperature within the chamber (200) and a temperature setting. Thus, the temperature within the chamber (200) is controlled by the temperature controller (241), and the amount of heat emitted by respective heating elements (210, 220, 230) while the temperature within the chamber (200) is below the temperature setting is controlled by the respective variable energy controllers (211, 221, 231)..</p> |
