Vaillant Printed Circuit Board 20036861

Vaillant printed circuit board for ecoTEC VU (condensing) boilers. The control centre of a boiler, the printed circuit board, monitors and controls every process occurring throughout a system via switches, thermostats and sensors. It enforces safety measures too, shutting down boiler functions if internal readings indicate any type of fault, such as high pressure or low water levels.
