Abstract (en)

Method (100) for controlling the operation of a combustion appliance (2), in particular a gas boiler operating at least in a first heat modulation range and a second heat modulation range, the method (100) comprising monitoring (S101) the combustion process of the appliance (2) through a sensor (6) measuring a physical value, in particular an oxygen sensor or an ionization sensor; controlling (S102) an air to fuel gas ratio in a gas mixture through a pneumatic gas valve (3) when the combustion appliance (2) operates in the first heat modulation range; and controlling (S103) the air to fuel gas ratio in a gas mixture through an electronically controlled gas valve (5) when the combustion appliance (2) operates in the second heat modulation range, wherein the method (100) comprises adjusting (S104) the electronically controlled gas valve (5) by varying a gas flow passing through said electronically controlled gas valve (5) based on a sensor signal generated by said sensor (6), when the combustion appliance (2) operates in the second heat modulation range.
