Vaillant 0010028086 printed circuit board

This Vaillant printed circuit board is a genuine spare part for Guernsey/Jersey only (condensing), ecoTEC VU (condensing), ecoTEC VUW (condensing) and ecoTEC VUI (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.
