The Ariston Air Pressure Switch is a safety device which ensures the fan is in full working order. It ensures that if the fan fails within the boiler, there will not be a build up of toxic gases with no means of venting them. The Printed Circuit Board closely monitors the air pressure switch to make sure it is fully functional before the unit is fired up, preventing the appliance from starting without one of its key safety features.
