3. MAIN CHARACTERISTICS
• 2 frequency inverters for the pumps control.
• Wall-mounted
• Control and safety system against overload.
• Control and safety system against dry run.
• ART function (Automatic Reset Test). If the device has been stopped due to the action of the safety sys-
tem against over-current, the ART tries to connect the pump, with a programmed periodicity because
the water supply could have been restored
• Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC
mode keeping the configuration parameters (see "CONFIGURATION" chapter).
• STC function ( Smart Temperature Control ). When the temperature of the electronic board reaches
85ºC, the spin frequency of the pump decreases automatically, decreasing that way the heat generation
but keeping the water supply.
• External pressure transducer (4.20 mA) under demand.
• External programable input with three options: Level, ON/OFF and Second pressure.
• Volt-free contact for monitoring the alarms displayed in screen originated by irregularities or
problems of the system (accessory).
Control panel (Fig.1):
• LCD screen, for alarm menu with permanent pressure indication.
• START/STOP push-buttons to act by hand each one of the pumps
• ENTER pushbutton to save data in memory.
• ON/OFF pushbutton to change rom AUTOMATIC to MANUAL mode or vice versa.
• MENU push-button
• Keyboard for the access to programming menu.
• Digital gauge.
• Register of operational controls: infomation about operating hours, counter of starts, counter of con-
nections to the power supply.
• Register of alarms: information about type and number of alarms since the starting up of the device.
