cable supplied with the boiler, order it exclu-
sively from Sime.
The power supply must be single-phase
230V - 50 Hz through a main switch pro-
tected by a fuse with a distance of at least
3 mm between contacts.
NOTE: The boiler must be connected with
an efficient grounding system.
SIME shall not be held liable for injury or
damage resulting from failure to ground
the boiler.
ATTENTION: Before every intervention on
the boiler, cut off the electricity supply by
means of the main switch of the system,
since even if the boiler is "OFF", the elec-
trical panel remains connected to the
electricity.
2.11.1 Chronothermostat connection
Remove the boiler casing, tilt the control
panel and connect the chronothermostat
to the 6 pole terminal board as indicated in
the boiler electrical diagram
(see para-
graph 2.12) after having removed the exi-
sting bridge.
The chronothermostat to be used must be
of a class conforming to the standard EN
60730.1 (clean electrical contact).
2.11.2 Remote control CR 63
connection (optionals)
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 unit allows
for complete remote control of the boiler,
except release of the boiler. Whenn the con-
nection has been made the boiler display
will show the following message:
Cr .
For installation and use of the remote con-
trol, follow the instructions in the package.
2.11.3 External sensor connection
(optional)
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 4 .
2.11.4 Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electronic
systems. The electrical connections to the
boiler refer to the wording on the diagram
(fig. 13). The zone valve control starts at
every demand for heating of the remote
control.
