HO: Operating hours

Indicates, on two lines, the hours of inverter activation and pump operating hours.

6.3 Setpoint menu

From the main menu, press and hold MODE and SET simultaneously until "SP" appears on display (or use
the buttons + or – in the selection menu).
Buttons + and – enable respectively to increase and decrease the system pressurisation value.
To exit the current menu and return to the main menu, press SET.
This menu enables the user to set the system operating pressure.
The pressure range depends on the sensor used (see PR: Pressure sensor section 6.5.7) and varies as
shown in Table 16. System pressure can be displayed in [bar] or [psi] depending on measurement system
used.
Type of sensor used
16 bar
25 bar
40 bar
6.3.1

SP: Setting the setpoint pressure

Pressure to apply to the system if the auxiliary pressure regulation functions are not active.
6.3.2

Auxiliary pressure settings

The inverter can vary the set point pressure according to the status of the inputs; up to 4 auxiliary pressure
values can be set for a total of 5 different set points. For the electrical connections, refer to paragraph
2.2.4.2, and for software settings, refer to paragraph 6.6.13.3.
Se sono attive contemporaneamente più funzioni pressione ausiliarie associate a più ingressi,
l'inverter realizzerà la pressione minore di tutte quelle attivate.
The auxiliary set points are disabled if the flow sensor is not used (FI=0) and when FZ is used in
minimum frequency mode (FZ ≠ 0).
