Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electro-
nic systems. Where necessary, the para-
meters 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). Description of the letters indicating

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
spacing 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 pro-
vide 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
Remote control
SIME HOME
connection (optional)
The boiler is designed for connection to a
remote control unit, supplied on request
(SIME HOME code 8092280/81).
The remote control SIME HOME unit allows
for complete remote control 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).
2.9.3
External sensor connection
(supplied with)
The boiler is designed for connection to
an external temperature sensor, supplied
with (code 8094101), which can automa-
tically 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
.
2.9.4
D.H.W. sensor connection
in vers. “25 T - 35 T ErP”
The
“25 T - 35 T ErP”
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 ErP” version
is designed for connection to a remote
boiling 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.
