Abstract
A heating control system that includes a heating unit with a constant burner and a pulsed burner. The constant burner is configured to remain active during operation. The pulsed burner is configured to toggle between an active mode and an inactive mode. The heating control system further includes a memory operable to store a temperature map that maps temperatures to percentages of a period that the pulsed burner is active and a microprocessor operably coupled to the heating unit and the memory. The microprocessor is configured to transmit a first electrical signal to activate the constant burner, obtain a temperature set point, determine the percentage of the period that the pulsed burner is active using the temperature set point and the temperature map, and transmit a second electrical signal to toggle the pulsed burner based on the determination of the percentage of the period that the pulsed burner is active.
