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-

The chronothermostat to be used must be
of a class conforming to the standard EN
2. 1 1.5 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 diagrams (see
fig. 12 and 12/a).
Zone valve control is activated with every
heating request from remote control.

2. 1 1.2 Climatic regulator CR 63
connection (optional)
The boiler is designed for connection to a
remote control unit CR 63 code 8092219
coupled to an optional expansion kit code
8092240.
The remote control CR 63 unit allows for
complete remote control of the boiler,
except release of the boiler.
Whenn the connection has been made the

It is possible to make corrections to the
values read by the drill acting on the PAR 4.
2. 1 1.4 D.H.W. sensor connection
vers. "12 T"
The "12 T" version is provided with a
D.H.W. sensor (SB) linked to the connector
CN5. When the boiler is coupled to an
external boiling unit, introduce the sensor
into the special sleeve in the boiling unit.
ATTENTION: The "12 T" version is desi-
gned for connection to a remote boiling
unit, for use ONLY FOR HEATING it is
necessary:
