BAG 3 AP
9
The ambient thermostats (TA) and/or chrono-thermostats
(CT) of systems must have adequate dry contact and work
with a mains voltage of 230 Vac; they must be connected
using a cable of 0,5 mm
2
section and adequate electric
voltage (230 Vac), removing the shunt.
9
The load represented by the pump will weigh direct-
ly on the corresponding ambient thermostat (TA) and/or
chrono-thermostat (CT), therefore the TA and/or CT contact
must be adapted to the application and be compatible with
the electrical rate of the pump not less than 6A (230Vac-
50Hz).
Connecting the BAG 3 to the boiler
− Connect the BAG 3 to the boiler (GEN) as indicated in the
diagram below.

Connect the mammut (B-B) of the BAG 3 to the mammut (TA)
of the boiler using a cable with a minimum section 2x0.5
mm
2
(please refer to the wiring diagram in the instruction
booklet for the installer of the speci fi c boiler).
9
When using a phase-phase power supply, use a tester to
determine which of the two wires has the greater potential
compared to the earth and connect it to the L terminal. Con-
nect the remaining wire to the N terminal.
9
For fl oating power supplies, i.e. those which have no earth
connection, an insulation transformer must be used with a
secondary unit connected to the earth.
9
It is mandatory:
− to use a multi-pole trip-switch to disconnect the line in
compliance with CEI-EN standards (contact opening at
least 3 mm)
− to use cables with a 1.5 mm
2
section and respect the L
(phase) - N (neutral) connection
− that the amperage on the switch is adequate for the boil-
er’s electrical power rating. Please refer to the technical
data to check
− the electrical power rating for the model installed
− to connect the appliance to an ef fi cient earthing system
− to ensure that access to the power socket is protected af-
ter installation.
0
The use of gas or water pipes to earth this appliance is strict-
ly prohibited.
9
The manufacturer declines any liability for damage caused
due to the lack of a proper earthing system or failure to
comply with the wiring diagrams.
3 COMMISSIONING
3.1 First start-up
Before starting up the BAG
3
, check that the plumbing and elec-
trical connections have been carried out correctly.
3.2 Setting the circulation units
The BAG 3 is equipped with digitally controlled high ef fi ciency
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 energy
(P1) as shown in the table below.
