CONNECT 1D LE
b
The ambient thermostats (TA) and/or chrono-thermostats (CT)
of the low and high temperature systems must be connected
directly to the
CONNECT LE
using a cable with a minimum sec-
tion of 1 mm
2
b
The load represented by the pump will weigh directly on the
corresponding ambient thermostat (TA) and/or chrono-thermo-
stat (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
CONNECT LE
to the boiler
- Connect the
CONNECT LE
to the boiler (GEN) as indicated in
the diagram below.
CONNECT 3D LE - CONNECT 2D LE
CONNECT1D LE
b
Connect the mammut (B-B) of the
CONNECT LE
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 book-
let for the installer of the specific boiler).
b
When using a phase-phase power supply, use a tester to deter-
mine which of the two wires has the greater potential compared
to the earth and connect it to the L terminal. Connect the re-
maining wire to the N terminal.
b
For floating power supplies, i.e. those which have no earth con-
nection, an insulation transformer must be used with a second-
ary unit connected to the earth.
b
It is mandatory:
- to use a multi-pole trip-switch to disconnect the line in compli-
ance 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 boiler’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 efficient earthing system
- to ensure that access to the power socket is protected after
installation.
a
The use of gas or water pipes to earth this appliance is strictly
prohibited.
b
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
CONNECT LE
, check that the plumbing and
electrical connections have been carried out correctly.
3 .2 Setting the circulation units
The
CONNECT LE
is equipped with digitally controlled high efficiency
electronic circulation units. Below is a description of the main char-
acteristics 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/pur-
ple (B) and four yellow LED (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).
