2.4 Configuration of the Integrated Inverter

The system is configured by the manufacturer to satisfy the majority of installation cases, that is:
 Operation at constant pressure;
 Set-Point (desired value of constant pressure):SP = 3.0 bar
 Reduction of pressure to restart: RP = 0.5 bar
 Anti-cycling function: Disabled
 Anti-freeze function: Enabled
However, all these parameters and many others can be set by the user. There are many other operating modes and
accessory functions. Thanks to the different possible settings and the availability of configurable input and output channels, it
is possible to adapt the inverter operation to the requirements of various systems.
For the definition of the parameters SP and RP, the pressure at which the system starts has the value:
Pstart = SP – RP
The system does not work if the utility is at a height higher than the equivalent in metres of water column of the
Pstart (consider 1 bar = 10 m water column): for the default configuration, if the utility is at a height of at least 27m
the system does not start.

2.5 Priming

At each switch-in, the system checks the presence of water in delivery for the first 10 seconds.
If a flow of water is detected in delivery, the pump is considered primed and starts its regular work.
If a regular flow in delivery is not detected, the system asks for confirmation to enter the priming procedure and shows
the pop-up in the figure:

Figure 7: Do not leave cable connected at only one end

For example: 3.0 – 0.5 = 2.5 bar in the default configuration
