3.11.4 Display of active settings
With the circulator powered, press briefly on the button (A) to view the active
configuration of the circulator. The LEDs indicate the active settings.
In this phase no variations can be made to the circulator configuration. Two
seconds after the button (A) has been pressed the user interface returns to
the normal operating status display.
3.11.5 Key lock function
The purpose of the key lock function is to prevent accidental modifications
to the settings or the improper use of the circulator.
When the key lock function is activated, long-pressing the button (A) is
prevented. This prevents the user from entering the circulator's operating
modes setting section.
Enabling/disabling the key lock function is achieved by pressing the button
(A) for more than 10 seconds. During this step all of the LEDs (C) will flash
for 1 second.
3.11.6 Changing the operating mode
In normal operating conditions the circulator works with the factory settings
or the last settings carried out.
To change the configuration:
Ensure that the key lock function is deactivated.
Press the button (A) for more than 2 seconds until the LEDs begin to flash.
Short-press the button (A) within 10 seconds and the user interface will move
on to display the next settings. The various available settings will appear in
a cyclic sequence.
If the button (A) is not pressed, the last setting will be stored.
