The control automat (3) guaranteesthat the system pressure which is set in the control is kept constant within tight limits. Thesignal that is necessary for this is sent to the automat by the pressure sensor (6). When thetemperature rises, the pressure in the system increases. The overflow valve (5) opens andlets the expansion water flow into the Flexcon M-P diaphragm expansion vessel. When thetemperature drops, the pressure in the system decreases. If the pressure falls below the setsystem pressure, the pump (4) switches on, and is switched off when the system pressureis reached. A check and a continuous indication of the filling level in the display (3) preventsthe pump (4) from running dry or the vessel (1) from being filled to an unallowably highlevel. The Flexcon M-P pump automat can be fitted with the following microprocessorcontrols:• Easycontrol automatThe Easycontrol automat is designed for single installations (a Flexcon M-P expansionautomat with coupling vessel). For operation, see pages 11 to 15.• Flexcon control automatThe Flexcon control automat is prepared for single installations, and for failure change-overoperation by two pumps. For operation, see pages 16 to 21.5
