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 active
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.
> 10 s
Changing the operating mode
When operating normally the circulator works with factory settings or
the last setting carried out.
To change the configuration:
Make sure that the key lock function is disabled.
Press the key (A) for more than 2 seconds until the LEDs start to blink.
By briefly pressing the key (A), within 10 seconds the user interface
will pass to a display of the successive settings. The various available
settings will appear in a cyclical sequence
If the key (A) is not pressed, the last setting selected will be saved.
