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 things,
resulting from the failure to provide for

connection (fig. 15 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 sec-
tion 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 (6-7).
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 contact 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.

External temperature
sensor connection
(fig. 15 pos. C)
The cables must comply with low safety vol-
tage requirements of EN 60730.
