If there are several alarms the circulator will display only the
alarm with the highest priority.
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 configura-
tion. Two seconds after the button (A) has been pressed the user
interface returns to the normal operating status display.
Key lock function
The purpose of the key lock function is to prevent accidental modifi-
cations 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.
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 avail-
able settings will appear in a cyclic sequence.
If the button (A) is not pressed, the last setting will be stored.
