The Riello Air Pressure Switch, also known as the APS is used as a safety instrument to ensure the fan is fully operational. The fan prevents a build-up of dangerous gases within the appliance by venting the fumes out of the property safely. The air pressure switch is monitored by the printed circuit board, ensuring that it is fully functional. If the air pressure switch is not operating correctly, the printed circuit board will stop the appliance from firing up.
