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.
2.6.1
Room stat connection
(fig. 6 pos. A)
In order to have access to the connector of
the electronic panel (3), remove the cover of
the control panel and, after having removed
the bridge, electrically connect the room
stat to the terminals TA (5-6). The thermo-
stat or chronothermostat, whose installa-
tion allows a better regulation of the tempe-
rature and comfor t of the environment,
must be class II in compliance with norm EN
60730.1 (clean electrical contact).
ATTENTION: The application of the grid
voltage to the connector ends (3) dama-
ges irreparably the control panel. Before
the connection make sure that there is
no voltage.
2.6.2
“Logica Remote Control”
connection (fig. 6 pos. B)
The electrical systems must be in com-
pliance wit h t he local r egulations and
cables must be positioned in compliance
with the specifications for safety low volta-
ge EN 60730. For lengths up to 25 m use
cables with a section of 0.25 mm
2
and for
lengths greater than 50 m use cables with
a section of 0.5 mm
2
.
First of all assemble and cable the base (2)
then insert the apparatus that will start up
as soon as it receives power. To access the
connector (3) remove the cover of control
panel and electrically connect the climate
control to the terminals CR (6-7).
ATTENTION:
External voltage cannot be connected to
terminals 1-2-3-4 of the base (2). To ter-
minals 3-4, the telephone remote control
switch of the telephone may be connec-
ted with a zero potential contact or win-
dow contact.
A type of electronic instrument for the
control of civil plants via a telephone line,
which may be mentioned, is the model
TEL 30.4 LANDIS & STAEFA.
