METHOD FOR REGULATING A GAS MIXTURE BY USING A GAS SENSOR AND A GAS MIXTURE SENSOR

A method for regulating a gas mixture formed from a gas and a fuel gas in a fuel gas-operated heating appliance, wherein the gas mixture is created by providing and mixing a gas quantity by way of a first control element and a fuel gas quantity by way of a second control element, wherein a microther...

Beschreibung
Zusammenfassung:	A method for regulating a gas mixture formed from a gas and a fuel gas in a fuel gas-operated heating appliance, wherein the gas mixture is created by providing and mixing a gas quantity by way of a first control element and a fuel gas quantity by way of a second control element, wherein a microthermal gas sensor and a gas mixture sensor are used and sensor signals are relayed to a controller, and wherein upon change in the detected sensor signal [of the] gas sensor the newly detected sensor signal of the gas sensor is compared to reference values which have been measured in the laboratory and saved in a table of values in the controller and from this a target value of the sensor signal of the gas mixture sensor is determined without a mixture ratio of the gas mixture composed of fuel gas and gas being changed.
