Ariston 65104321 Pressure Switch

This Ariston Pressure Switch (Proportional) is compatible with a range of Ariston Systems including the following:

• Ariston Genus HE24
• Ariston Genus HE24 System
• Ariston Genus HE30
• Ariston Genus HE30 System
• Ariston Genus HE38

When water pressure drops below 0.5 bar of pressure, a pressure sensor inside the boiler detects the change and causes the boiler to switch off.

This is a cautionary measure to prevent the boiler from operating without enough water and, as result, overheating.
