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 conti-
nue to manage information visualisation,
the setting of the sanitary set and the hea-
ting of the second circuit, and the boiler
parameters by means of the keys on the
control panel. For installation and use of
the climatic regulator, follow the instruc-
tions included in the packaging.
NOTE: Reset parameter 10 to 2 (PAR 10
= 2).

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).

2.9.5 D.H.W. sensor connection
in vers. "12-20-25-30-35 T"
The "12-20-25-30-35 T" version is provi-
ded 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 "T" version is designed
for connection to a remote boiling unit,
for use ONLY FOR HEATING it is neces-
sary:
- to disconnect the D.H.W. sensor (SB);
- set PAR 2 and 4.
Operations must be carried out by autho-
rized and qualified technicians.
