Vaillant 130391 control ignition printed control board

This Vaillant printed circuit board is a genuine spare part for THERMOcompact VU (fan-assisted) and TURBOmax VUW (fan-assisted) 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.
