Abstract (en)
[origin: WO2020148434A1] The invention relates to a method for controlling a gas mixture (5, 105) formed from a gas (2, 104) and a fuel gas (1, 103) in a fuel-gas-operated heating device, wherein: the gas mixture is created by a gas amount and a fuel gas amount being provided by a first actuator (4, 107) and a second actuator (3, 102) respectively and then mixed; a microthermal gas mixture sensor (6, 106, 108), which detects at least one material property of the gas mixture (5, 105), is supplied with the gas mixture and continuously transmits a sensor signal dependent on the particular gas mixture to a control device (7, 100); the control device (7, 100) compares the detected sensor signal with a set-point value of the sensor signal and, in the event that the detected sensor signal deviates from the set-point sensor signal, actuates at least one of the first and second actuators, as a result of which the gas mixture (5, 105) is adjusted by increasing or reducing the gas amount and/or increasing or reducing the fuel gas amount, until the set-point value of the sensor signal is achieved.
