2.9 ELECTRICAL CONNECTION
The boiler is supplied with an electric supply
cable, which in case of replacement must
be requested from SIME. The supply must
be carried out with a monophase voltage of
230V - 50 Hz via a general switch protec-
ted by fuses, with a distance between con-
tacts of at least 3 mm. Observe the L-N
polarities and the earth connection.
NOTE: Device must be connected to an
efficient earthing system. SIME declines
any responsibility for damages to persons
or objects due to failing to earth the boiler.
Always turn off the power supply before
doing any work on the electrical panel.
2.9.1 Room stat connection
(fig. 17 pos. A)
In order to have access to the connector of
the electronic panel (3), remove the cover of
the control panel and electrically connect the
room stat to the TA terminals (5-6) after
having removed the existing bridge. The ther-
mostat or chronothermostat to be used,
whose installation allows a better regulation
of the temperature and comfort of the envi-
ronment, must be class II in compliance with
norm EN 60730.1 (clean electrical contact).
ATTENTION: The introduction of grid electri-
city to the connector (3) irreversibly dama-
ges the regulation panel. Before connection
ensure that there is no grid electricity.
2.9.2 Connection “Logica Remote
Control ” (fig. 17 pos. B)
The electrical plants must be in compliance
with local norms and cables must be laid
observing the safety low voltage specifica-
tions EN 60730. For lengths up to 25 m
use cables with sections of 0.25 square
mm and for lengths greater than 50 m use
cables with sections of 0.5 square mm.
First of all assemble and cable the socket
(2) and then insert the apparatus that will
start as soon as it receives electricity. To
have access to the connector (3) remove
the cover of the control panel and electri-
cally connect the climate regulator to the
terminals CR (6-7) .
ATTENTION: External electricity cannot
be connected to terminals 1-2-3-4 of the
socket. The telereducer of the telephone
with a contact of zero potential or a win-
dow contact can be connected to termi-
nals 3-4. A type of electronic apparatus
for the control of civil plants via a telepho-
ne line that can be pointed out is the
model TEL 30.4 LANDIS & STAEFA.
2.9.3 Connection external temperature
sensor (fig. 17 pos. C)
The cables must be laid observing the
saf e ty low volt age specif ications EN
60730. For lengths up to 25 m use cables
with sections of 0.25 square mm and for
lengths greater than 50 m use cables with
sections of 0.5 square mm. To have access
to the connector of the boiler (3) remove
the cover of the control panel and electri-
cally connect the external temperature
sensor to the terminals SE (8-9).
