PRESSURE BOOSTING FUNCTION

The E.box panel can be used for making a system to increase water pressure. As control inputs, either pressure switches on a pressure sensor
can be used. To operate, the panel requires an expansion vessel.
5.1

Expansion vessel

In pressure boosting it is necessary to use an expansion vessel of at least 19 litres per pump.
5.2

Electrical connections of pump and supply

Connect the supply line and the pumps as described in the chapter ELECTRICAL CONNECTIONS.
