Abstract (en)
[origin: EP0390964A2] In a control device for regulation in the same direction of gas supply and combustion air supply to a burner (11), the heat- requirement regulator (6) controls the speed of a blower (8, 9) providing the combustion air. A differential pressure signal corresponding to the quantity of combustion air provided is supplied to a control module (19) designed as an amplifying servo-pressure regulator, which provides the control pressure for a gas-regulating valve (15) designed as a servo-valve. <IMAGE>
