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.

interfaces switches to the “Operating status display”.
