When there are several alarms, the circulator will only
display the alarm with the highest priority.
Displaying the active settings
With the circulator powered up, briefly press the key (A) to display
the active configuration of the circulator. The LEDs indicate the ac-
tive settings.
No changes to the configuration of the circulator can be made in
this phase. Two seconds after the key (A) has been pressed, the
user interface returns to the normal display of the operating status.
Key lock function
The key lock function prevents any accidental modification of the
settings or the improper use of the circulator.
When the key lock function is activated, prolonged pressure of the
key (A) is inhibited. This prevents the user entering the section for
setting the circulator's operating modes.
The key lock function can be enabled/disabled by pressing the key
(A) for more than 10 seconds. During this passage all the LEDs (C)
blink for 1 second.
