It is able to maintain constant water pressure. The display facilitates the control and the selection of the operating parameters also through a guided procedure of first start (wizard) during which the user is guided step by step in the insertion of the operating parameters. The variable frequency drive allows energy saving and water hammer protection. Inside the body there are a pressure sensor, a flow switch and a non-return valve. Integrated thermo-amperometric protection against abnormal voltages, overtemperature and frost. In groups, the second and third pumps are started in cascade, when the first pump reaches the maximum rotation speed. The pressure is adjustable by the user. It is possible to set working times for each pump with exchange of operation after the set time. The display shows: operating frequency, instantaneous pressure, current consumption, operating alarms.
