restart the pump.
If the parameter SP is not correctly set, the protection against
water lack may not work correctly.
4.1.2 - 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 Anti-Cycling function can be excluded or activated in Basic or Smart
mode (par 7.6.12).
In Basic mode, once the condition of recurrence is detected the pump
stops and remains waiting to be manually reset. This condition is commu-
nicated to the user by the lighting of the red "Alarm" led and the appear-
ance of the word "ANTICYCLING" 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.
4.1.3 - Anti-Freeze (Protection against freezing of water in the sys-
tem)
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 (Fig.1 Face E) and put it away in a sheltered place.

4.1.4 - "BP1" Blockage due to fault of the internal pressure sensor

If the device detects a fault in the 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.
4.1.5 - "BP2" Blockage due to reading error on the remote pressure
sensor
BP2 indicates a warning on the remote pressure sensor connected to the
control unit.
4.1.6 - "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.

4.1.7 - "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.

4.2 - 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.
