INSTALLER PARAMETERS:
These parameters can be found on hidden pages and usually they should only be changed in the
installation phase. To access these pages switch the device to Stand-by and keep the "+" and "-"
buttons pressed down together for 5 seconds. Once you have entered the hidden menu, use the
"<<" and ">>" buttons to scroll the pages and the "+" and "-" buttons to change the parameters.

(pressure oscillations with consequent changes in the speed of the motor) it is advisable to set the
lower PID values. On the other hand, when the system's reaction to pressure variations is too slow
we recommend increasing the PID value (max. 50). The default value set by the manufacturer is
25. Use the "+" and "-" buttons to change the values of the PID parameter.
to a depth of 8-10 metres a 60% value is recommended, for pumps submersed over 10 metres the
parameter should be set at 70%. In any case, it is useful to increase this parameter when the start-
up of the motor pump is too slow and there is a significant loss of pressure in the system during
this phase. Use the "+" and "-" buttons to change the minimum frequency values.
and the Sirio Entry. The intervention time of the protection in case of excessive absorption is
inversely proportional to the overload, therefore a slight overload shall trigger longer intervention
times while a great overload will lead to a rapid interruption. The parameter can be set at a value
between 0.5 a 9.7 A. When the device is switched on if the Imax parameter is set at 0.5 A
Language: The language used for the menus and the alarm
messages can be selected by the user. Use the + and – buttons to
alter the parameter setting.
Soft-Start: Use this parameter to enable or de-activate the "soft-
start" function. When soft-start is activated the pump starts
gradually, otherwise it starts always at maximum speed for 1
second before beginning r.p.m. modulation. To change the
parameter, press "+" or "-".
PID Control: This parameter is used to set the speed of reaction of
the system to changes in pressure (accelerations and decelerations).
Low PID values represent a slow but more accurate reaction (more
gradual start and stop) while the higher values of this parameter can
be used for a higher reaction speed. When the system is unstable
Minimum frequency: Use this parameter to set the minimum
frequency of the motor pump power supply (i.e. the number of
rotations). The value is expressed as percentage of the maximum
frequency value. The parameter can be set at the following values:
50, 60 or 70%. For surface pumps a 50% minimum frequency is
recommended as set by the manufacturer, for pumps submersed up
Imax: this parameter is used to set the maximum current that must
be absorbed by the motor pump in ordinary conditions, so that the
motor will stop in case of excessive absorption. The motor shall
stop also if the current measured during operation is lower than 0.5
A following the interruption of the connection between the motor
