Display of the active settings
With the circulator powered, the active configuration of the circulator
can be viewed (fig. S) by briefly pressing the button (A). The LEDs
indicate the active settings.
No change to the configuration of the circulator can be made at this
stage. Two seconds after of pressing the button (A), the user inter-
face returns to the normal display of the operating status.
Key lock function
The key lock function is designed to prevent an accidental change of
settings or misuse of the circulator.
When the lock function is activated, the prolonged pressing of button
(A) is inhibited. This prevents the user from entering the setting sec-
tion of the circulator operating mode.
The enabling/disabling of the key lock function is made by pressing
button (A) for more than 10 seconds (fig. T). During this step, all
LEDs (C) flashes for 1 second.

By not pressing button (A) the last setting chosen is stored (fig. S).
Pressing button (A) allows to go back to the "display of the active
settings" and verify that LEDs (B) and (C) indicate, for 2 seconds, the
last setting made
By not pressing button (A) for more than 2 seconds, the user inter-
face will "display the operating status".
