<p>A control circuit for a liquid fuel combustion apparatus which employs a differential amplifier and square-wave generator to maintain a strong constant combustion in the burner until the differential amplifier senses that room temperature has approached a preselected target temperature, at which point the differential amplifier operates to alter the square-wave generator output to gradually reduce the combustion rate in an inverse proportion to room temperature as the target temperature is being reached. The differential amplifier subsequentially controls the square-wave generator in a manner which causes fuel to be available at a rate necessary and sufficient for maintaining the target temperature.</p> |
