2.9.6 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 (figg. 11-
11/a). The zone valve control starts at
every demand for heating of the zone 1 (it
is from part of the TA1 or the CR).

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.
2.9.1 Chronothermostat connection
Connect the chronothermostat as indica-
ted in the boiler electrical diagram
(see
figs. 11 e 11/a) after having removed the
existing bridge.
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 continue to manage
information visualisation, the setting of the
sanitary set and the heating of the second
circuit, and the boiler paramet er s by
means of the keys on the control panel. For
installation and use of the climatic regula-
tor, 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
(code 8092226).
The remote control unit CR 73 allows for
complete remote control of the boiler,
except release of the boiler.
The boiler display will show the following
message:
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
(supplied with)
The boiler is designed for connection to an
external temperature sensor, supplied with
(code 8094101), which can automatically
regulate the temperature value of the boi-
ler output according to the external tempe-
rature. For installation, follow the instruc-
tion in the package. It is possible to make
corrections to the values read by the drill
acting on the
PAR 11 .
2.9.5 D.H.W. sensor connection
in vers. “25 T - 35 T”
The “25 T - 35 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 “25 T - 35 T ” version is
designed for connection to a remote boi-
ling unit, for use ONLY FOR HEATING it is
necessary:
- to disconnect the D.H.W. sensor (SB);
- set PAR 2 and 5.
Operations must be carried out by autho-
rized and qualified technicians.
