point.
However, our system is equipped with the "Antifreeze" function, which automatically rotates the pump if the temperature falls to values close to
zero. The water inside the pump is thus kept moving and slightly heated, thus limiting the risk of the formation of ice.
This function protects the pump, but it cannot generally prevent the formation of ice in the swimming pool or in other parts of
the system.
The temperature sensor is fitted close to the motor and does not directly feel the water temperature, but that of the pump motor
assembly.
If the pump is in a technical room, the outdoor temperature may be lower, even much lower, than the one measured by the
sensor.
ATTENTION: The Antifreeze protection works only as long as the system is regularly powered: with the electric power
disconnected or in the absence of current (even accidental, such as after a blackout) the protection cannot work. So it is
advisable not to leave the system loaded during long periods of frost in winter, but empty it accurately.
In cases of inactivity, it is advised not to disconnect the electric power to keep the antilock protection active (see the following
paragraph).
The intervention of the Antifreeze function turns the pump even if the system is in STOP status (white led
not influenced by the active operating mode (manual or automatic).
If you want to prevent the Antifreeze function intervening and turning on the motor, the function must be disabled.
‐
The "Antifreeze" item on the menu allows you to:
‐
enable or disable the function (factory value: enabled);
select the pump rotation speed during the intervention of Antifreeze: between 20%
‐
and 100%;
choose the intervention temperature of Antifreeze, between 4°C and 10°C
(between 40°F and 50°F).
The factory values are given in chapter 8.
6.2.8
Anti-Lock (Protection against mechanical blocking of the pump)
This function prevents mechanical blocks occurring in the case of long inactivity; it acts by periodically turning the pump, at a very low speed
that does not create a head. When the function is enabled, the pump performs an unlocking cycle lasting about one minute every 23 hours
(elapsed without any start of the pump).
The "Antilock" item on the menu allows you to enable or disable the function (factory value: enabled).
ATTENTION: The Antilock protection works only as long as the system is regularly powered: with the electric power disconnected or
in the absence of current (even accidental, such as if the automatic switches have blown due to a storm) the protection cannot work.
The intervention of the Antilock function turns the pump even if the system is in STOP status (white led
influenced by the active operating mode (manual or automatic).
If you want to prevent the Antilock function intervening and turning on the motor, the function must be disabled.
6.2.9
Fault History
This item on the menu allows you to consult the fault history and erase it.
Pressing "ENTER" on the second item gives access to the page that allows you to delete the
list.
Instead, if you press "ENTER" on the first item, it gives access to the list of faults in the
memory, which you can scroll through with the arrow keys (not indicated on the display).
The faults are shown in chronological order, starting from the most recent one, up to the one
that occurred farthest back in time. The list is scrolled with the up arrow and down arrow
keys.
The maximum number of faults that can be stored and displayed is 16; when this number is
reached, the list starts to overwrite the oldest ones.
