block manually by pressing the "+" and "-" keys simultaneously and then releasing them. If the alarm status remains, or if
the user does not intervene by restoring the flow of water and resetting the pump, the automatic restart will try to restart
the pump.
If the parameter SP is not correctly set, the protection against water lack may not work correctly.

6.1.2 Anti-Cycling (Protection against continuous cycles without utility request))

If there are leaks in the delivery section of the plant, the system starts and stops cyclically even if no water is intentionally
being drawn: even just a slight leak (a few ml) can cause a fall in pressure which in turn starts the electropump.
The electronic control of the system is able to detect the presence of the leak, based on its recurrence.
The anticycling function can be disabled (AY: OFF) or activated in Normal mode (AY: ON) or in Smart mode
SMART) (par 5.6.6).
In Normal mode, once the condition of recurrence is detected, the pump stops and remains waiting to be manually reset.
This condition is communicated to the user by the lighting of the red "Alarm" led and the appearance of the word "EY" on
the display. After the leak has been removed, you can manually force restart by simultaneously pressing and releasing the
"+" and "-" keys.
In Smart mode, once the leak condition is detected, the parameter RP is increased to decrease the number of starts over
time.

6.1.3 Anti-Freeze (Protection against freezing of water in the system)

The change of state of water from liquid to solid involves an increase in volume. It is therefore essential to ensure that the
system does not remain full of water with temperatures close to freezing point, to avoid breakages of the system. This is
the reason why it is recommended to empty any electropump that is going to remain unused during the winter. However,
this system has a protection that prevents ice formation inside by activating the electropump when the temperature falls to
values close to freezing point. In this way the water inside is heated and freezing prevented.
The Anti-Freeze protection works only if the system is regularly fed: with the plug disconnected or in the absence
of current the protection cannot work.
However, it is advised not to leave the system full during long periods of inactivity: drain the system accurately
through the drainage cap and put it away in a sheltered place.

6.1.4 "BP1" Blockage due to fault of the delivery pressure sensor (system pressurisation)

If the device detects a fault in the delivery pressure sensor the pump remains blocked and the error signal "BP1" is given.
This status begins as soon as the problem is detected and ends automatically when correct conditions have been restored.

6.1.5 "PB" Blockage due to supply voltage outside specifications

This occurs when the allowed line voltage at the supply terminal assumes values outside the specifications. It is reset only
automatically when the voltage at the terminal returns within the allowed values.

6.1.6 "SC" Blockage due to short circuit between the motor phases

The device is provided with protection against the direct short circuit which may occur between the motor phases. When
this blockage is indicated you can attempt to restore operation by simultaneously holding down the + and – keys, but this
will not have any effect until 10 seconds have passed since the moment the short circuit occurred.
6.2

Manual reset of error conditions

In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the + and – keys.
6.3

Self-reset of error conditions

For some malfunctions and blockage conditions, the system attempts automatic self-reset.
"BL" Blockage due to water lack
"PB" Blockage due to line voltage outside specifications
"OT" Blockage due to overheating of the power stages
"OC" Blockage due to motor overload
"BP" Blockage due to fault of the pressure sensor
For example, if the system is blocked due to water lack, the device automatically starts a test procedure to check whether
the machine is really left definitively and permanently dry. If during the sequence of operations an attempted reset is
successful (for example, the water comes back), the procedure is interrupted and normal operation is resumed.
Table 9 shows the sequences of the operations performed by the device for the different types of blockage.
