2.11 ELECTRICAL WIRING
If you must replace the electric power cable
supplied with the boiler, order it exclusively
from Sime. The power supply must be
single-phase 230V - 50 Hz through a main
switch protected by a fuse with a distance of
at least 3 mm between contacts.
The boiler must be connected with an effi-
cient 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
Connect the chronothermostat as indica-
ted in the boiler electrical diagram (see
paragraph 2.12) 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).
2.11.3 Remote control SIME HOME
connection (optional)
The boiler is designed for connection to a
remote control unit, supplied on request
(code 8092280/81).
The remote control unit SIME HOME 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).
2.11.4 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.
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.
2.11.5 D.H.W. sensor connection in vers.
“20-25 BFT”
The “20-25 BFT” version is provided with
D.H.W. sensor (SB) linked to the connector
CN5. When the boiler is coupled to D.H.W.
storage tank, introduce the sensor into the
special sleeve in the D.H.W. storage tank.
ATTENTION: The “BFT” version is designed
for connection to D.H.W. storage tank, for
use ONLY FOR HEATING it is necessary:
- to disconnect the D.H.W. sensor (SB);
- set PAR 2=4.
All modules are designed to be used by
qualified technical personnel.

2.11.6 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 (figs. 13 -
13/a - 13/b).
The zone valve control starts at every
demand for heating of the zone 1 (it is from
part of the TA1 or the CR).
