Cavo PWM per pompa De Dietrich 7219249

The pump PWM cable is a specialized wiring harness for connecting pumps with PWM (pulse-width modulation) control in modern heating systems. It enables precise speed regulation of the pump, improving energy efficiency and comfort. This cable is an important spare part for boiler and burner repairs where variable-speed pumps are used. Replacing a faulty PWM cable restores optimal pump performance and helps reduce energy consumption in your heating equipment.
