The Alpha pressure switch is designed as a spare for Pro Tec, C, CB, CDS, CD, CDX, HE, District Heating and SY boilers. A pressure switch is an important safety device that ensures the boiler fan is working properly and prevents pressure build-up. The printed circuit board of the unit closely monitors pressure switches to ensure they are fully functional before powering on the system, preventing the appliance from starting without the presence and operation of key safety features.
