PWM wiring extractor fan De Dietrich 710062300

The PWM wiring for the extractor fan is a key electrical component that controls the fan speed in modern heating systems. Using pulse-width modulation, this wiring enables precise regulation of the fan motor, optimizing combustion and efficiency. It is commonly used in condensing boilers and gas burners where variable speed fans are employed. Replacing a faulty PWM wiring can resolve issues like erratic fan operation or error codes, ensuring your system runs quietly and efficiently.
