The Alpha air pressure switch enables safety protocols to ensure that the fan is fully operational. It ensures that if the fan within the boiler fails, toxic gases do not accumulate with no way to vent them. The printed circuit board closely monitors the air pressure switch to ensure that it is fully functional before the unit is powered on, preventing the appliance from starting without one of its critical safety mechanisms.
