摘要： A method for detecting faulty operation of a gas blower driven by an electronically commutated DC motor. The DC motor of the gas blower is controlled by an integrated electronic motor control circuit. The electrical current draw, required in operation to reach a predetermined blower speed of the gas blower, is measured. It is measured as a measured variable via the electronic motor control circuit. The electronic motor control circuit performs a plausibility check of the measured electrical current draw. The measured value of the electrical current draw, at a predetermined blower speed, is compared to a current draw reference value characteristic stored in the electronic motor control circuit. Thus, a warning and/or an error code is issued by the electronic motor control circuit. The warning is based on deviation of the measured value of the electrical current draw beyond a tolerance range around the reference characteristic.

摘要： 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.

摘要： A method for the safety-oriented control of at least one final control element of at least one electrically actuated gas valve, which is switched by means of two relays connected in series, wherein the final control element is activated only if the first relay and the second relay are tripped, wherein a flow of current over the first relay is monitored by a first monitoring device, a flow of current over the second relay is monitored by a second monitoring device, and a control device is programmed in such a way that the final control element is activated by tripping the two relays only if both the first monitoring device and the second monitoring device report to the control device that there is no flow of current before the activation.

摘要： A method of monitoring a flame during gas combustion in a combustion chamber (10). A heating unit (1) has an evaluation unit, an extraction line (11) and a sensor (12). The sensor (12) is arranged in the extraction line (11) to detect thermal substance properties of the gas. Thus, it is determined if it is ambient air (B), a non-combusted fuel-air mixture (C) or particularly the hydrogen-air mixture, or a waste gas (A) generated during combustion. The sensor (12) transmits a recorded measured value to the evaluation unit. The evaluation unit uses the measured value to determine whether ambient air (B), the non-combusted fuel-air mixture (C), or waste gas (A) is flowing through the extraction line (11) and thereby determines whether the flame is burning or extinguished.

摘要： A gas control valve (1) has a central module (40), a control module (20) and a sensor module (30). Gas can flows through the central module (40) from a valve inlet (41) to a valve outlet (42). The control module (20) is directly on the central module (40) and controls a flow of the gas through the central module (40). A throttle element (23) is fluidically arranged between the valve inlet (41) and the valve outlet (42). The sensor module (30) is arranged directly on the central module (40) and has at least one sensor (31, 32) in operative connection with the gas flowing through the central module (40) through a gas inlet (44) fluidically arranged between the throttle element (23) and the valve outlet (42). In order to control the pressure, it detects a pressure difference between the gas flowing through the central module (40) and air having a reference pressure.
