VAIL 0020254533 PRINTED CIRCUIT BOARD

A genuine branded replacement part, this Vaillant printed circuit board is suitable for use in Guernsey/Jersey condensing appliances, ecoTEC VU, ecoTEC VUI and ecoTEC VUW condensing boilers. The control centre of a boiler, the printed circuit board (PCB) 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 fault such as high pressure or low water levels.
