4.3 Multi inverter operating parameters
The parameters displayed on the menu, in a multi-inverter configuration, can be classed as follows:
 Read-only parameters
 Local parameters
 Multi inverter system configuration parameters
in turn divided as
o Sensitive parameters
o Parameters with optional alignment
4.3.1 Parameters related to multi inverter systems
4.3.1.1 Local parameters
These are parameters that can differ from one inverter to another and in some cases actually need to be
different. For these parameters, automatic alignment of inverter configuration is not admitted. In the case of
manual assignment of addresses, these must all be different.
List of local parameters for inverters:
 CT Contrast
 FP Test frequency in manual mode
 RT Direction of rotation
 AD Address
 IC Reserve configuration
 RF Fault and warning reset
4.3.1.2 Sensitive parameters
These are parameters that must be aligned on the entire series for control purposes.
List of sensitive parameters:
 SP Setpoint pressure
 P1 Input 1 auxiliary pressure
 P2 Input 2 auxiliary pressure
 P3 Input 3 auxiliary pressure
 P4 Input 4 auxiliary pressure
 RP Pressure drop for restart
 FI Flow sensor
 FK K factor
 FD Pipe diameter
 FZ Zero flow frequency
 FT Min. flow threshold
 MP Minimum pressure pump stop due to water failure
 ET Exchange time
 NA Number of active inverters
 NC Number of simultaneous inverters
 CF Carrier frequency
 TB Dry run time
 T1 Shutdown time after low pressure signal
 T2 Shutdown time
 GI Integral gain
 GP Proportional gain
 I1 Input 1 setting
 I2 Input 2 setting
 I3 Input 3 setting
 I4 Input 4 setting
 OD Type of system
 PR Pressure sensor
