Function

The hot water temperature in the tank is controlled by a self-acting thermostat with a remote sensor placed in a sensor pocket located in the tank.

The self-acting thermostat is mounted directly on the PICV.

Benefits

• The PICV ensures balancing of the flow and eliminates the use of both static balancing valves and differential pressure control valves.
• Simple installation with no need of any control system.
• Low total pressure loss in the system due to simple design.
• The flow can be set directly on the PICV without the need of a manometer or a commissioning unit.
• The flow limiting feature of the PICV ensures a minimum Delta T for the water heating up the tank.

Considerations

• Legionella heating up cycles cannot be performed automatically.
• A metering station can be installed if additional flow verification is required by the witnessing authority.
