4. LED white warning light ( ), lit to indicate that the board is live; if it is blinking, it means that the board is live,
but the pump is not enabled (see "RUN/STOP" key below).
5. LED green warning light ( ), indicates that the pump is running.
6. (Four) keys "SET 1-4" for manual control of switching on, for directly selecting (or deselecting) a set flow or
speed (setpoint).
The table in chapter 8 shows the factory values of the setpoints associated with the keys from "SET1" to
"SET4". These values are suitable for most installations, but they can be easily changed if desired (see
6.2.2).
7.
Key for activating "QuickClean" mode, to command quick cleaning or quick recirculating with a high flow rate.
8. Key for enabling "Auto", mode, for activating the automatic control of the pump (which may be timed ("Timers")
or given by external signals ("EXT").
9.
Keys for navigating and accessing the menus:
the "ENTER" key allows you to access the menus and the items on which you are positioned;
the "arrow" keys allows you to move about on the display or in the active menu, and to select an item;
they also allow you to change the value of the selected item.
10. "OK" key, to confirm and to leave without saving the changes made.
11.
"ESC" key, to cancel any changes and leave (without saving).
12. "Reset" key, to cancel the alarms (faults) that may be in progress.
13. "RUN/STOP" key, to enable or disable running of the pump; the pump enabled status is indicated by the
steady lighting of the white LED
When the pump is running (green LED
operating condition, in both "Manual" and "Auto" mode.
However the "RUN/STOP" control is not direct starting control, but only an enabling: if it is pressed with
the pump stopped (green LED off), the pump starts only if a mode is active that contemplates switching
on at the current moment.
In STOP condition, when the white LED is blinking, the pump can never stop until "RUN/STOP" is
pressed.
The only exceptions:
- the "Antifreeze" function can start the pump even in STOP status, to avoid breakages due to frost (see
paragraph 6.2.8);
- the "Antilock" function can start the pump even in STOP status, to avoid metchanical blocking of the
impeller after long inactivity (paragraph 6.2.9).
The keyboard can be blocked with a ("Password"; in this way access to the functions can be restricted, to avoid
undesired intervention. See paragraph 6.2.1.7.

The information forms three groups:

o
the status (running, stopped) along with the current command (SET1 – SET3, QC, Timer A-H, etc.), or
any active Warnings and Faults; in the example in the figure: "System Running" indicates that the
system is active, commanded by "TIMER A".
