Gas-fired Boiler Differential Pressure Switch Viessmann 140/120 Pa A1JB/A1HB 30-34 kW 7856959

The differential pressure switch 7856959 for the Viessmann A1JB/A1HB 30-34 kW gas boiler plays an important role in controlling the air and gas pressure in the combustion system.

The differential pressure switch in a gas boiler monitors the pressure difference between the inlet and outlet to maintain the correct mixing of air and gas in the combustion chamber. It plays a role in the safe operation of the boiler by controlling the combustion parameters. For example, improper pressure can lead to improper combustion and increased carbon dioxide emissions, which is dangerous.

Proper operation of the differential pressure switch also contributes to boiler efficiency by helping to maintain optimal combustion conditions and preventing excessive fuel consumption.

Differential pressure range: 140/120 Pa.
