The manually assigned addresses can have values from 1 to 8.
Identical addresses are not admitted.
This situation makes communication between the inverters impossible and generates an error indicated by a blinking
E in the place of the machine address.
If selected assignment is automatic, each time the system is turned on, the addresses are assigned automatically and
may be different from the previous time; this has no effect on correct operation.
6.5.8 PR: Remote pressure sensor
The sensor must be connected to the specific input (See par. 2.3.5)
The PR parameter is used to select a remote pressure sensor. The default setting is with no sensor present.
When the sensor is active, the display shows an icon of a stylised sensor with a P inside it.
The remote pressure sensor operates in synergy with the internal sensor so that the pressure never falls below the
setpoint pressure in either of the two points in the system (internal and remote sensors). This allows compensation for
any pressure drops.
NOTE: in order to maintain the setpoint pressure in the point with lower pressure, the pressure in the other point may
be higher than the setpoint pressure.

The setpoint pressure is independent of the type of remote pressure sensor selected.
6.5.9 MS: Measurement system
This sets the measurement unit system; either international or Imperial The values displayed are shown in Table 21.
6.5.10 SX: Setpoint
Sets the maximum value that any one of the setpoints SP, P1, P2, P3 can have (P2 and P3 are available only on type
MT and T/T inverters).

6.6 Technical Assistance Menu

From the main menu, press and hold "MODE" & "SET" & "+" simultaneously until "TB" appears on display (or use the
buttons + or – in the selection menu). This menu enables the display and modification of various configuration
parameters. The MODE button enables the user to scroll through the menu pages, while buttons + and – enable
respectively to increase and decrease the value of the parameter concerned. To exit the current menu and return to
the main menu, press SET.
6.6.1 TB: Water failure block time
Entry of a water failure block delay time enables selection of the time (in seconds) taken by the inverter to notify of low
water levels on the electric pump.
Modifications to this parameter may be useful if a known delay exists between the moment in which the pump is
activated and the actual moment of supply. One example is that of a system where the electric pump intake line is
particularly long and is subject to small leaks. In this case it may occur that the pipeline empties, and even if the water
supply is regular, the electric pump takes some time to reload, deliver flow and pressurise the system.
6.6.2 T1: Shutdown time after low pressure signal
This sets the inverter shutdown time starting from reception of the low pressure signal (see Impostazione della
rilevazione di bassa pressione par. 6.6.15.5). The low pressure signal may be received on any of the 3 inputs, by
suitably configuring the input (Setup degli ingressi digitali ausiliari IN1, IN2, IN3 par. 6.6.15).
T1 can be set between 0 and 12 s. The default setting is 2 s.
