A Worcester Bosch tail piece designed for the air pressure switch of CBi Series, Si/C1 Series, CDi Series, SBi Series, Highflow, i Junior Series and RD Series boilers. A vital safety device, an air pressure switch ensures the boiler fan is working correctly and prevents a build up of toxic gases with no means of venting them in case of a fan failure. The unit's PCB closely monitors the air pressure switch to ensure it is fully functional before firing the system up, keeping the appliance from starting without the presence and operation of key safety features.
