Abstract
A system for controlling temperature in an enclosure operates in a low heat or a high heat mode with flame always present. The presently intended use is for providing a cooking grill with a controlled temperature cooking space. An electrically controlled valve having high flow rate and low flow rate settings is interposed in the fuel line for at least one of the burners in the grill. A temperature sensor signals cooking space temperature to a controller that may be a microprocessor. The system includes a keyboard allowing the user to communicate a selected set point to the microprocessor and the microprocessor communicates status to a display. The microprocessor selects the setting of the electrically controlled valve. In a preferred embodiment, the electrically controlled valve is placed in series fuel flow with one of the manually adjustable valves commonly found on cooking grills.
