The Vaillant printed circuit board is the control centre of the appliance. It monitors and controls every process that occurs via the thermostats, switches and sensors . It also enforces the safety protocols, making sure that the boiler ceases to function if any of the internal readings point to an error in the boiler's operation. The printed circuit board is effectively the brain of the boiler. It is programmed to ensure everything is running as it should.
Voltage is 230 V
