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 must
be 230V - 50Hz single-phase through a
fused main switch, with at least 3 mm spa-
cing between contacts. Respect the L and N
polarities and the earth connection.
NOTE: SIME declines all responsibility for
injury or damage to persons, animals or
property, resulting from the failure to pro-
vide for proper earthing of the appliance.
2.7.1
Room stat connection
(fig. 8 pos. A)
To gain access to the electronic board con-
nector (3), remove the control panel cover
and connect the room stat to the terminals
TA after having removed the jumper.
The t her mos t at or timer -t her mos t at,
recommended for better room temperatu-
re control, must be class II as specified by
standard EN 60730.1 (clean contact).
WARNING: Applying mains voltage to the
terminals of conector (3) will irreparably
damage the control board. Make sure
that any connections to be made are not
carrying mains voltage.
2.7.2
“Logica Remote Control”
connection (fig. 8 pos. B)
The electrical plant must comply with local
standards and all cables must comply with
low safety voltage requirements of EN
60730. For lengths up to 25 m, use cables
of section 0.25 mm
2
, for longer lengths up
to 50 m use cables of section 0.5 mm
2
.
First of all, assemble and wire the socket
(2), then insert the equipment which will
start-up as soon as it receives current.
To gain access to connector (3) remove the
control panel cover and connect the climate
regulator to terminals CR.
WARNING: External voltage must not be
connected to terminals 1-2-3-4 of the
"Logica Remote Control". A telephone
remote switch with a zero potential con-
tact or a window contact can be connected
to terminals 3-4. Equipment for the
checking of civil plants via a telephone line
includes the model TEL 30.4 LANDIS &
STAEFA.
2.7.3
External temperature
sensor connection (fig. 8 pos. C)
The cables must comply with low safety vol-
tage requirements of EN 60730.
For lengths up to 25 m, use cables of sec-
tion 0.25 mm
2
, for longer lengths up to 50
m use cables of section 0.5 mm
2
.
To gain access to boiler connector (3) remo-
ve the control panel cover and connect the
external temperature sensor to terminals
SE.
– If the terminal discharges into a pathway or passageway check that combustion products will not cause nuisance
and that the terminal will not obstruct the passageway.
– Where the lowest part of the terminal is fitted less than 2 m (78 in) above ground, above a balcony or above a flat
roof to which people have access, the terminal MUST be protected by a purpose designed guard. Terminal guards
are available from Quinnell, Barrett, and Quinnell, Old Kent Road, London. State model C2, (G.C. Part No 382946).
– Where the terminal is fitted within 850 mm (34 in) of a plastic or painted gutter, or 450 mm (18 in) of painted
eaves, an aluminium shield at least 1,500 mm (59 in) long must be fitted to the underside of the painted surface.
– The air inlet/outlet flue duct MUST NOT be closer than 25 mm (1 in) to combustible material.
– In certain weather conditions the terminal may emit a plume of steam. This is normal but positions where this would
cause a nuisance should be avoided.
