IMPORTANT: THE PARAMETERS KI and KP ARE CRITICAL BECAUSE THEY CHANGE THE BEHAVIOUR
OF THE INVERTER, AND WRONG SETTING CAN CAUSE SYSTEM MALFUNCTIONING
The parameters KP and KI constantly define the operating frequency of the inverter-controlled pump,
depending on the fluctuation of system pressure compared to the set pressure.
The more the system is elastic, the greater the proportionate parameter must be. The more rigid the
system is, the smaller the proportionate parameter must be. Limits vary from 1 to 50 with step 1.
The integrative parameter must be higher in the presence of fast changes in system pressure and
lower in the presence of pressure oscillations. Limits vary from 0 to 50 with step 1.
NOTE. The parameters KP and KI are automatically changed when any changes are made to the RF
parameter (see 2.7 RESPONSE FACTOR parameter); this operation is performed to adapt the speed of
response of the device.

By means of this function, the parameters entered in the BASE SETUP and ADV SETUP menus are reset
to factory setting, while the HARDWARE SETUP parameters are not reset.
To reset all the parameters, including the HARDWARE SETUP parameters, the function in the EXTENDED
MENU must be used; use of the menu protected by password is restricted to after-sales centres or the
factory.

HARDWARE CONFIGURATION
(HARDWARE SETUP)
This menu contains all the parameters needed to set up the signal inputs and outputs on the control board.
The control logics of the flow and pressure signal and type of connected sensors can also be set up.
