• Installer level : Allows editing the parameters related to pump operation in the hydraulic system on which it is
installed. Password 1, default 001.
• Advanced level : Allows editing the parameters that so critical that they may compromise the life of the device,
the pump, and the system if they are set incorrectly. Password 2, default 002 .
Within each menu, it is possible to change the relative access password.
NOTE
When an incorrect password is entered to access both the installer and advanced level, the parame-
ters can only be displayed but not edited.
In case of loss of the password, contact the technical support service to obtain the universal pass-
word.

9.6. Control parameters
Parameter Default Description 1 2 3 4 5 6
Control mode
1. Constant value
2. Fix speed
3. Constant value 2 set
4. Fix speed 2 values
5. External speed
6. MPPT
MPPT The following control modes can be selected:
1. Constant value: the device varies the speed of the pump in
such a way as to keep the set value constant regardless of
water consumption.
2. Fix speed: the device powers the pump at the set frequen-
cy.
3. Constant value 2 set: two desired values can be selected
by opening or closing digital input 2.
4. Fix speed 2 values: two desired frequency values can be
selected by opening or closing digital input 2.
5. External speed: it is possible to control the motor frequen-
cy through an analog signal connected to analog input 4.
6. MPPT: the device varies the speed of the pump to maxi-
mize the power obtained from the photovoltaic panels.

Max alarm value
p = XX.X [bar]
10 Value that can be reached in the system beyond which, even
in constant frequency operating mode, the pump is stopped
and an alarm signal is emitted. The pump is restarted only
after the measured value has dropped below the maximum
alarm value for more than 5 seconds. x x x x x x
Min alarm value
p = XX.X [bar]
0 Minimum value that can be reached in the system below
which, even in constant frequency operating mode, the pump
is stopped and an alarm signal is emitted. The pump is restar-
ted only after the measured value has risen above the mini-
mum alarm value for more than 5 seconds. x x x x x x
