2.8 POSITIONING THE
OUTLET TERMINALS
The outlet terminals for forced-draught
appliances may be located in the external
perimeter walls of the building.
To provide some indications of possible solu-
tions, Table 3 gives the minimum distances
to be observed, with reference to the type
of building shown in fig. 10.

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.

Connect the chronothermostat as indica-
2.9.5 Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electronic
systems. Where necessary, the parame-
ters to be set in the boiler are given.
The electrical connections to the boiler
refer to the wording on the diagram (fig.
11). The zone valve control starts at every
demand for heating of the zone 1 (it is from
part of the TA1 or the CR).

11) after having removed the existing brid-
ge. The chronothermostat to be used must
be of a class conforming to the standard
EN 607301 (clean electrical contact).
2.9.2 Climatic regulator CR 53
connection (optional)
The boiler is designed for connectio to a cli-
matic regulator, supplied on request (code
8092227), for the management of a hea-
ting circuit. The electronic card will conti-
nue to manage information visualisation,
the setting of the sanitary set and the hea-
ting of the second circuit, and the boiler
parameters by means of the keys on the
control panel.
For installation and use of the climatic regu-
lator, follow the instructions included in the
packaging.
NOTE: Reset parameter 10 to 2 (PAR 10 = 2).
2.9.3 Remote control CR 73
connection (optional)
The boiler is designed for connection to a
remote control unit, supplied on request

For installation and use of the remote con-
trol, follow the instructions in the package.
NOTE: Ensure PAR 10 set to 1 (PAR 10 = 1).
2.9.4 External sensor connection
The boiler is designed for connection to an
external temperature sensor, supplied on
request (code 8094101), which can auto-
matically regulate the temperature value of
the boiler output according to the external
temperature. For installation, follow the
instruction in the package.
It is possible to make corrections to the
values read by the drill acting on the PAR
11.
