2. 1 0 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
things, resulting from the failure to provi-
de for proper earthing of the appliance.
2. 1 0. 1 Room stat connection
(fig. 18 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 ther-
mostat or timer-thermostat, recommended
for better room temperature control, must
be class II as specified by standard EN
60730. 1 (clean contact).

WARNING: Applying mains voltage to the
terminals of connector (3) will irreparably
damage the control board. Make sure
that any connections to be made are not
carrying mains voltage.
2. 1 0.2 "Logica Remote Control"
connection (fig. 18 pos. B)
The electrical plant must comply with
local standards and all cables must com-
ply with low safety voltage requirements
of EN 60730. For lengths up to 25 m,
use cables of section 0.25 mm
ger lengths up to 50 m use cables of sec-
tion 0.5 mm
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 cli-
mate regulator to terminals CR (6-7).
WARNING: External voltage must not be
connected to terminals 1-2-3-4 of the
spcket (2).
On terminals 3-4 can be connected a
telephone remote switch with a zero

potential contact or a window contact .
Equipment for the checking of civil plants
via a telephone line includes the model
TEL 30.4 LANDIS & STAEFA.
2. 1 0.3 External temperature sensor
connection (fig. 18 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 , for longer lengths up to 50
2
m use cables of section 0.5 mm
To gain access to boiler connector (3) remo-
ve the control panel cover and connect the
external temperature sensor to terminals
SE (8-9).
2. 1 0.4 D.H.W. sensor
connection "25 BFT"
The model "25 BFT" boiler is supplied with a
D.H.W. sensor (SB) connected to connector
J2 (3 fig. 18). When the boiler is connected
up the "BT100" unit, introduce the sensor
into the sheath on the flange for inspection,
control and cleaning of the tank unit.
