SINGLE SPLITTING KIT (ALTERNATIVE ACCESSORY)

For special installations of the fumes inlet/outlet ducts, the
single splitting kit (C), supplied as an accessory, can be
used. This accessory, in fact, can be used to move the inlet
and outlet in any direction. This type of installation makes
it possible to discharge exhaust fumes both outside the
building and into single flue ducts. Comburent air can be
drawn in at a different location from that of the flue terminal.
The splitting kit is fixed to the boiler turret (100/60 mm) and
allows the comburent air and outlet fumes to enter/leave the
two separate ducts (80 mm). For further information, read the
assembly instructions supplied with the accessory.
SOME OUTLET DUCT INSTALLATION EXAMPLES AND THEIR RELATIVE MAXIMUM LENGTHS ARE SHOWN IN ANNEX
"SECTION" D AT THE END OF THIS MANUAL.

14. ELECTRICAL CONNECTIONS

This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety
regulations. Connect the boiler to a 230V single-phase earthed power supply using the supplied three-pin cable, observing correct
Live-Neutral polarity.
Use a double-pole switch with a contact separation of at least 3 mm.
When replacing the power supply cable, fit a harmonised "HAR H05 VV-F" 3x0.75 mm2 cable with a maximum diameter of 8 mm.
The 2A fast-blowing fuses are incorporated in the power supply terminal block (to check and/or replace the fuse, pull out the black
fuse carrier).
Rotate the control box downwards and access terminal blocks M1 and M2, used for the electrical connections, by removing the
safety cover.
Terminal block M1 and terminal block M3 are high voltage. Before making connections, make sure the appliance is disconnected
from the power supply.
TERMINAL BLOCK M1 (observe the polarity L - N)
(L) = Live (brown)
(N) = Neutral (light blue).
= Earth (yellow-green).
(1) (2) = contact for Room Thermostat.
TERMINAL BLOCK M2
Terminals 1 (back-lighting) - 2 (earth) - 3 (+12V): connection
to wall-fitted Control Panel (low voltage).
Terminals 4 - 5 (common): External Probe connection
(supplied as an accessory).
Terminals 6 - 5 (common): 2nd Auxiliary Probe (probes for
solar plant, cascade system, etc.).
Terminals 7 - 5 (common): 1st Auxiliary Probe (probes for
solar plant, cascade system, etc.).
Terminal 8: not used.
Terminals 9-10: connection of the DHW boiler probe (for
heating only boilers).
TERMINAL BLOCK M3
Terminals 1...5: not used.
Terminals 6 - 7: Multifunction relay contact (e.g.: zone system section 14.3).

14.1 CONNECTING THE ROOM THERMOSTAT

To connect the Room Thermostat to the boiler, proceed as described below:
• switch off the boiler;
• access the terminal block M1;
• remove the jumper from the ends of contacts 1-2 and connect the wires of the Room Thermostat;
• switch on the boiler and make sure the Room Thermostat works correctly.
Put back the jumper on terminals 1-2 of boiler terminal block M1 if the ambient thermostat is not used or if the wall-mounted
Control panel is installed (section 14.2).
