The Riello air pressure switch, also known as the APS is a safety mechanism used to ensure the fan is in full working order. The fan prevents a build-up of noxious fumes within the appliance, extracting them safely. The air pressure switch is tracked by the printed circuit board (PCB), ensuring that it is fully operational; if the air pressure switch is not operating correctly, the PCB will restrict the appliance from firing up.
Fits a number of ambirad appliances
