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).
3 KEYBOARD AND DISPLAY
The machine interface comprises a yellow Oled display (64 X 128) with black background and 5 buttons named
"MODE", "SET", "+", "-", "RUN/STOP" see Figure 6. The display shows the inverter values and statuses, and indicates
the functions of the various parameters. The button functions are summarised in Table 11.
When pressed for a longer interval, buttons +/- enable automatic increase/decrease of the selected parameter. If
button +/- is pressed for more than 3 seconds, the automatic increase/decrease speed is increased.
Figure 5: Appearance of the user interface
The MODE button enables the user to move to the next items in the same menu. When
pressed for at least 1 sec it enables the user to skip to the previous menu item.
The SET button enables the user to exit the current menu.
This decreases the current parameter (if modifiable).
This increases the current parameter (if modifiable).
