To facilitate the work of the user, the RP setting page, highlighted below the symbol RP, shows the effective
restart pressure; see Figure 16.

AD: Address configuration

This is only applicable on multi-inverter systems. It sets the communication address to be assigned to the
inverter. The possible values are: automatic (default), or manually assigned address.
The manually assigned addresses can have values from 1 to 8. Configuration of the addresses must be uniform
for all inverters in the series: either all automatic or all manual. Identical addresses are not admitted.
If the address assignment modes are mixed (some manual and some automatic), and also if an address is
duplicated, the relative error is shown. The error is indicated with a flashing "E" in place of the unit 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.
6.5.7

PR: Pressure sensor

Setting of the type of pressure sensor used. This parameter enables selection of a ratiometric or current type
pressure sensor. For each type of sensor, different full scales can be selected. When a ratiometric sensor is
selected (default) the input Press 1 must be used for connection. When a 4-20mA current sensor is used, the
relative screw terminals on the input terminal board must be used.
(See Collegamento del sensore di pressione par 2.2.3.1)
PR value Type of sensor
0 6.6 Ratiometric (0-5V)
1 6.7 Ratiometric (0-5V)
2 6.8 Ratiometric (0-5V)
3 4-20 mA
4 4-20 mA
5 4-20 mA
The setting of the pressure sensor does not depend on the pressure to be obtained, but on the sensor
to be fitted on the system
