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).
4. THE KEYPAD AND THE DISPLAY
The user interface consists of a keypad with LCD display and POWER, COMMUNICATION and ALARM LEDs as seen in Figure
3.
The display shows the values and the statuses of the device, with indications on the functionality of the various parameters.
The functions of the keys are summed up in Table 1.
The MODE key allows you to move on to the next items in the same menu. Holding it down for at least 1
sec allows you to skip to previous menu item.
The SET key allows you to leave the current menu.
Decreases the current parameter (if it is an editable parameter).
Increases the current parameter (if it is an editable parameter).
Holding down the "+" key or the "-" key allows the automatic increase/decrease of the parameter selected. After the "+" key
or the "-" key has been held down for 3 seconds, the automatic increase/decrease speed increases.
When the + key or the - key is pressed the selected value is modified and saved immediately in the permanent
memory (EEprom). If the machine is switched off, even accidentally, in this phase it does not cause the loss of
the parameter that has just been set.
The SET key is only for leaving the current menu and is not necessary for saving the changes made. Only in
particular cases described in the following paragraphs are some values updated by pressing "SET" or "MODE".
