The Alpha air pressure switch serves as a safety mechanism, ensuring that the fan is fully operational. It ensures that if the fan within the boiler fails, there will be no build-up of noxious fumes with no way to vent them. The printed circuit board closely monitors the air pressure switch to ensure that it is fully operational before the unit is powered on, preventing the appliance from starting without one of its critical safety devices.
