3.9 ELECTRICAL CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler
m u s t b e 2 3 0 V - 5 0 H z s i n g l e - p h a s e
through a fused main switch, with at least
3 mm spacing between contacts. Respect
the L and N polarities and the earth con-
nection.
NOTE: SIME declines all responsibility for
injury or damage to persons, animals or
things, resulting from the failure to pro-
vide for proper earthing of the appliance.
3.9.1 Room stat connection
To gain access to the TA-CR-SE-SB (J2)
electronic board connector, remove the
control panel cover and connect the room
st at to the terminals 5-6 af ter having
removed the jumper (fig. 18).
The thermostat or timer-thermostat, rec-
ommended for better room temperature
control, must be class II as specified by
standard EN 60730.1 (clean contact).
Warning: Applying mains voltage to the
ter minals of boar d TA-CR-SE-SB will
irreparably damage the control board.
Make sure that any connections to be
made are not carrying mains voltage.
3.9.2 Connection “Logica Remote
Control ” (fig. 18 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
s e c t i o n s o f 0 . 2 5 s q u a r e m m a n d f o r
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 h a v e a c c e s s t o t h e c o n n e c t o r ( 3 )
remove the cover of the control panel and
electrically 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 telephone line
that can be pointed out is the model TEL
30.4 LANDIS & STAEFA.
3.9.3 Connection external temperature
sensor (fig. 18 pos. C)
The cables must be laid observing the safe-
ty low voltage specifications EN 60730. For
lengths up to 25 m use cables with sec-
tions of 0.25 square mm and for lengths
greater than 50 m use cables with sec-
tions of 0.5 square mm. To have access to
the connector of the boiler (3) remove the
cover of the control panel and electrically
connect the external temperature sensor
to the terminals SE (8-9).
