Attention: the use of this operating mode may help create situations of risk due to high water temperatures being
reached inside the pump (see Warnings, Chap. 2).
5.4.1 RI: Speed setting
Sets the motor speed in rpm. Allows you to force the number of revolutions at a predetermined value.
If the rotations made differ from the rotation setting "RI", the number of rotations set and the number of rotations made are
displayed alternately. When the number of rotations made is displayed, an "A" appears alongside the unit of measurement.
Each time the "+" or "-" is pressed to modify the RI, the display automatically shows the number of rotations set.
5.4.2 VP: Pressure display
Plant pressure measured in [bar] or [psi] depending on the measuring system used.
5.4.3 VF: Flow display
Displays the flow in the chosen unit of measure. The measuring unit may be [l/min] o [gal/min] vedi par. 5.5.3 - MS:
Measuring system
5.4.4 PO: Absorbed power display
Power absorbed by the electropump in [kW].
If the maximum power absorbed is exceeded and power limitation is activated, the PO parameter symbol flashes.
5.4.5 C1: Phase current display
Motor phase current in [A].
If the maximum current supplied is exceeded temporarily, the C1 symbol flashes to indicate that the motor overload
protection is being activated and if operation continues in this condition, the overload protection is activated.

Settings menu

From the main menu, keep the "MODE" & "SET" & "-" keys pressed simultaneously until the first parameter of the settings
menu appears on the display.
The menu allows you to view and modify various configuration parameters: the MODE key allows you to scroll through the
menu pages, the + and – keys allow you respectively to increase and decrease the value of the parameter concerned.
Press SET to leave this menu and return to the main menu.
5.5.1 RP: Setting the pressure fall to restart
Expresses the fall in pressure with respect to the SP value which causes restarting of the pump.
For example if the setpoint pressure is 3 bar (43.5 psi) and RP è 0,5 bar (7.3 psi) the pump will restart at 2,5 bar (35.3 psi).
RP can be set from a minimum of 0.1 to a maximum of 1,5 bar (21.8 psi). In particular conditions (for example in the case
of a setpoint lower than the RP) it may be limited automatically.
Attention: the setting of particular values of this parameter with relation to the system may help create situations
of risk due to high water temperatures being reached inside the pump (see Warnings, Chap. 2).
5.5.2 OD: Type of plant
Possible values "R" and "E" referring to a rigid system and an elastic system.
The device leaves the factory with mode "R" suitable for the majority of systems. In the presence of swings in pressure
that cannot be stabilised by adjusting the parameters GI and GP, change to mode "E".
IMPORTANT: The regulating parameters GP and GI also change in the two configurations. In addition the GP and GI
values set in mode "R" are stored in a different memory from the GP and GI values set in mode "E". So, for example, when
passing to mode 2, the GB value of mode 1 is replaced by the GB value of mode "E" but it is kept and will reappear again
when returning to mode "R". The same value shown on the display has a different weight in one mode or in the other
because the control algorithm is different.
5.5.3 MS: Measuring system
Set the measuring system, choosing between metric and imperial units. The quantities displayed are shown in Table 6.
NOTE: The flow in English-speaking units (gal/min) is indicated adopting a conversion factor of 1 gal = 4.0 litres,
corresponding to the metric gallon.
