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