Patent attributes
An appliance comprises a burner and a compressor for supplying pressurized air to the burner in order to create a low-pressure area for siphoning fuel to the burner. A flame sensor senses for the presence or absence of a flame in the burner and a temperature sensor senses an actual temperature of the appliance. There is a controller in communication with the temperature sensor. The controller shuts off the compressor and overrides the flame sensor such that the appliance acts as if a flame is present when the temperature sensor senses that the actual temperature of the appliance is greater than a maximum threshold temperature. The controller starts up the compressor overriding the flame sensor such that the appliance acts as if a flame is absent when the temperature sensor senses that the actual temperature of appliance is less than a minimum threshold temperature.
