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:
Pressing "-" confirms that you do not want to start the priming procedure and the product remains in alarm status,
deactivating the pop-up.
Pressing "+" starts the priming procedure: the pump starts and remains on for a maximum time of 2 minutes during
which the safety block for dry operation is not tripped.
As soon as the product detects a regular flow in delivery, it leaves the priming procedure and starts its regular
operation.
If the system is still not primed after 2 minutes of the procedure, the inverter stops the pump and the display
reproposes the same water lack message, allowing the procedure to be repeated.
Prolonged dry operation of the electropump may cause damage to the pump.
2.6 Operation
Once the electropump is primed, the system starts regular operation according to the configured parameters: it starts
automatically when the tap is turned on, supplies water at the set pressure (SP), keeps the pressure constant even
when other taps are turned on, stops automatically after time T2 once the switching off conditions are reached (T2 can
be set by the user, factory value 10 sec).

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