Abstract
A burner control provides a pulsed flame sequence in response to a user's selective manipulation of an actuator through a range of response. A microcontroller-based control module switches both a burner ignitor control and an electric valve for gas supply to the burner in a predetermined time sequence depending upon the actuator position within the predetermined range. Preferably, one or more of a plurality of burners on a single cooking top are controlled for pulsed sequence operation, and a single actuator for each channel, preferably in a form of a rotary knob, provides a simple user interface for utilizing the pulsed flame sequence, preferably in a low gas flow or simmer cooking range.
