<p>An apparatus (5) for controlling a water-pressurization system can be installed in a hydraulic circuit (1). The system includes an electric pump (2) connected to the hydraulic circuit (1) for pumping water therein, and an expansion vessel (3), provided with a valve (4) for controlling the pressure of the chamber containing air inside it, connected to the hydraulic circuit (1), designed to compensate for the variations of pressure to which the hydraulic circuit (1) is subjected in the steps of delivery of water. The apparatus (5) further includes a pressure sensor (7), installed in a position corresponding to the control valve (4), for detecting the pressure of the chamber containing air, and an electronic control unit (6), electrically connected to said electric pump (2) and to the pressure sensor (7), designed to measure constantly the pressure of the chamber containing air by the pressure sensor (7), so as to regulate activation or deactivation of the electric pump (2) on the basis of the value of pressure detected.</p> |
