The Vaillant 130837 main printed circuit board (PCB) is the control centre of compatible Vaillant ecoMAX pro boilers. It monitors and controls the boiler’s processes via switches, thermostats and sensors, and enforces safety protocols so that the boiler stops operating if internal readings point to a fault. This is a genuine, new Vaillant part, supplied in original Vaillant packaging.
This Part Fits:
– Vaillant ecoMAX pro 18 E / VU 186-O (2003-2010)
– Vaillant ecoMAX pro 28 E / VU 286-O (2003-2010)
If you are unsure whether this board fits your boiler, please contact us before ordering so we can confirm compatibility.
