The Sime air pressure switch facilitates safety protocols by checking that the fan is fully operational. 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 PCB closely monitors the air pressure switch to make sure it is fully operational before the unit is fired up, preventing the appliance from starting without one of its key safety features.
