Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electronic
systems.
Where necessary, the parameters to be
set in the boiler are given.
The electrical connections to the boiler
refer to the wording on the diagrams (fig.
11).

2.8.1
Chronothermostat
connection
Connect the chronothermostat as indica-
ted in the boiler electrical diagram
(see fig.
11)
after having removed the existing brid-
ge.
The chronothermostat to be used must be
of a class conforming to the standard EN
607301 (clean electrical contact).
2.8.2
Climatic regulator CR53
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
cir cuit, and t he boiler paramet er s by
means of the keys on the control panel.
For installation and use of the climatic regu-
lator, follow the instructions included in the
packaging.
NOTE: Reset parameter 10 to 2 (PAR 10
= 2).
2.8.3
Remote control CR73
connection (optional)
The boiler is designed for connection to a
remote control unit (code 8092226).
The remote control unit CR73 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).
2.8.4
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. It is possible to make corrections
to the values read by the drill acting on the
PAR 11
.
2.8.5
D.H.W. sensor connection
The boiler is provided with a D.H.W. sensor
(SB) linked to the connector Cn5. (not connected)
When the boiler is coupled to an external
boiling unit, introduce the sensor into the
special sleeve in the boiling unit.
ATTENTION: The boiler is designed for
connection to a remote boiling unit, for
use FOR HEATING & DHW it is necessary:
- to connect the D.H.W. sensor (SB);
- set PAR 2 and 4.
Operations must be carried out by
authorised and qualified technicians.
