Below is an explanation of how to correctly connect the CONNECT LE to the various
devices and the boiler.
b
Before carrying out any electrical intervention, set the main system switch to
"off".
Connecting the
CONNECT LE
to the electrical power supply
- Pass the cable (2) which comes out of the electrical connection box (3) through
the cable feed-through (1) and connect it to the electrical power supply (phase-
neutral-earth) making sure not to connect it below the boiler fuse.

to the ambient thermostats/chrono-thermostats
- Carry out the connections of the ambient thermostats (TA) and/or chrono-thermostats
(CT) of each zone, as indicated in the diagram below. Before connection, eliminate the
relative jumper (TA1, TA2 or TA3).

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 section of 1 mm
2
.
b
The load represented by the pump will weigh directly 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
CONNECT LE
to the boiler
- Connect the
CONNECT LE
to the boiler (GEN) as indicated in the diagram
below.

to the mammut (TA) of the boiler
using a cable with a minimum section of 2x0.5 mm

(please refer to the wiring
diagram in the instruction booklet for the installer of the specific boiler).

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. Connect the remaining wire to the N terminal.
b
For floating power supplies, i.e. those which have no earth connection, an insula -
tion transformer must be used with a secondary unit connected to the earth.
b
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

section and respect the L (phase) - N (neutral) con-
nection
- 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.Com-
