3.2 Setting the circulation units
The BAG 3 is equipped with digitally controlled high efficiency
electronic circulation units. Below is a description of the main
characteristics and the procedures to be carried out in order to
set the required operation.
User interface
The user interface consists of a button (A), a two-colour LED red/
purple (B) and four yellow LED (C).
A B C
LED 1 LED 2 LED 3 LED 4 LED 5
The user interface allows the functions which are in operation
to be displayed (operating status, alarm status) and allows the
circulation unit operating mode to be set.
The performance data, indicated by the LED (B) and (C) is
always displayed during normal operation of the circulation
units while the parameters are set by pressing the button
(A).
Indication of the operating status
When the circulation unit is operating, the LED (B) is green The
four yellow LEDs (C) indicate the consumption of electrical ener-
gy (P1) as shown in the table below.

If more than one alarm activates, the circulation unit will
only display the alarm with the highest priority.
Active settings display
With the circulation unit powered, briefly press the button (A)
to see the active configuration of the circulation unit. The LEDs
indicate the active settings.
No changes can be made to the configuration of the circulation
unit in this phase. Two seconds after having pressed the button
(A), the user interface once again shows the normal display of
the operating status.
Button lock function
The button lock function is used to prevent any setting modifi-
cation being made accidentally or improper use of the circula-
tion unit.
When the button lock function is active, it is not possible to
press and hold the button (A). This prevents from entering the
settings section of the circulation unit operating modes.
Pressing the button (A) for more than 10 seconds enables/dis-
ables the button lock function. During this passage, all LEDs (C)
flash for 1 second.

Changing the operating mode
In normal operating conditions, the circulation unit operates
with the factory settings or the last settings made.
To change the configuration:
− Make sure that the button lock function is disabled.
− Press the button (A) for more than 2 seconds until the
leds begin to flash. Briefly press the button (A) and with-
in 10 seconds the user interface will change to display the
next series of settings. The settings available will appear
in sequence.
− If the button (A) is not pressed, the last setting selected
will be stored.
