6 - CIRCULATOR SETTINGS
Circulator residual discharge head
The boilers is equipped with an already hydraulically and electrically
connected circulator, whose useful available performance is indicated
in the graph.
The circulator comes set from the factory with a 6 metre discharge
head curve.
The boiler is equipped with an anti-blocking system which starts up
an operation cycle after every 24 hours in standby with the mode
selector in any position.
b
The "antiblocking" function is active only if the boiler is electrically
powered.
a
Operating the circulator without water is strictly forbidden.
If you need to use a different curve you can select the desired level
on the circulator.
Below the main characteristics and the ways to set up their desired
operation are listed.
User interface
The user interface is made up of a button (A), a two-coloured red /
green LED (B) and four yellow LEDs (C) arranged in a row.
The user interface allows the operating performance to be viewed
(operating status and alarm status) and it also allows the circulator
operating modes to be set.
The performance, indicated by the LEDs (B) and (C) is always visible
during normal operation of the circulator whereas the settings can be
carried out by pressing the button (A) .
Operating status indication
When the circulator is in operation the LED (B) is green. The four
yellow LEDs (C) indicate the electrical energy consumption (P1) as
shown in the following table

(*) For the power (P1) absorbed by the circulator see the indications
in the "Technical Data" table.
Alarm status indication
If the circulator has detected one or more alarms the two-coloured
LED (B) will be red. The four yellow LEDs (C) indicate the type of
alarm as shown in the following table.

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.
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.
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.

If the button (A) is pressed you can move back to the "active settings
display" again and check that the LEDs (B) and (C) indicate (for 2
seconds) the last setting carried out.
If the button (A) is not pressed for more than 2 seconds the user
interfaces switches to the "Operating status display".
The available settings are shown in figure along with the related
representation of LED (B) and (C).
