The inverter automatically regulates the rotation speed of the pump, shifting the work point, as necessary, to any part
of the area subtended by the maximum curve (100%).
Regulation during pumping can takes place in flow control mode or in fixed curve mode.
-
In "flow control" ("Flow") the system assesses the instantaneous flow of water and varies the pump speed so that
the flow corresponds to the setpoint, expressed in this case in "m
per minute). In this mode, the work point moves (ideally) on a vertical line, corresponding to the flow value chosen.
- In "fixed curve" mode

of the curve chosen, which is similar to the trend of fixed speed curves in traditional pumps.
Generally, when the work point falls below the maximum curve, the system reduces the absorbed power and thus
decreases the energy consumption.

3.1.2 Command modes

The system can operate in three control modes: "Manual" mode and "Auto" mode.
In "Manual" mode:
- The speeds are already pre-set but can be modified from the "Manual Speeds" menu or directly from
the home page in instantaneous mode (see par. 5.2)
- the operator manually commands the switching on of the pump by pressing the keys from "SET1" to
"SET4" or "QuickClean";
- the LED next to the key that has been pressed lights up (for example, if "SET1" is pressed the LED
above this key is lit).
In "Auto con Timers" mode:
- The speeds can be set from the "Timer Speeds" menu (par. 5.3).
- switching on and off are automatically commanded by Timers, which can be programmed as desired
on a weekly basis (see par. 5.3 Timer Setting menu);
In these first two modes the pump acts as a Master and works alone through its integrated control.
