7.3.1.2
Setting of pump speed (base controller featured)
If the constant water flow rate to the system is to be adjusted through adjustment of the speed of the pump present in the
unit, the inverter that controls it must be suitably adjusted.
The inverter installed in the unit is already factory preset to operate at a constant flow rate.
The frequency set at 50 Hz at the factory must be reduced until the desired flow rate is obtained.
Parameters must be entered on the inverter display to set up the desired water flow rate.
The inverter installed in the unit is already factory preset for the required type of adjustment.
It is however necessary to complete the calibration according to the specific requirements of the system by following the
instructions given below.
The parameters are edited using the keypad present on the inverter.

The parameters are edited using the keypad present on the inverter.
Access and edit only the parameters shown here.
Do not edit other parameters without the Manufacturer's prior permission.
The inverter installed in the unit is already factory preset to operate at a constant flow rate.
The frequency set at 50 Hz at the factory must be reduced until the desired flow rate is obtained.
For free cooling units, set the frequency value with and without free cooling active and then with and without
the head losses of the free cooling coil.
For free cooling units with decoupling exchanger (FC/NG) where the head losses do not change, only one
value is set.
Do not set the water flow rate outside the operating limits allowed in the Technical Catalogue.
