In the following screen (fig.1) it's possible to see the different unit of measure with the following order:
Motor frequency (0.0Hz);
Current consumption (0.0A);
Plant pressure (0.00bar);
Reference pressure (3.00bar).
(fig.1)
In order to change the reference pressure and carry it for example to 4.00 bar, you just have to click
on the "MENÙ" button as shown in fig.2

As you can see, the pressure of reference will be default to
3.00bar.
This means that, when the reference pressure reaches 3.00
bar the inverter will start to modulate until it exceeds 3.00 bar
and in the meanwhile the motor frequency will reaches the
percentage of minimum PID (P237 default 70% = 35Hz).

After about 20 minutes the inverter will turn off completely

automatically.

At this point it will be in a mode called SLEEP and will start
when the system pressure will fall below the SETPOINT
pressure less the rate of awakening (P237 default 5% = 0.5
bar).
Es. P237 b= 5%=0.5 bar
PRef= 3.00 bar
Pump ignition threshold = 3.00 - 0.5 = 2.5 bar
