supplied with the boiler, order it exclusively
from CLIMIT .
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 . CLIMIT 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 electri-
cal panel remains connected to the electri-
city .

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 diagrams
(figs . 13-13/a) . The zone valve control starts
at every demand for heating of the remote
control .

The chronothermostat to be used must be
of a class conforming to the standard EN

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 connection has been made the
boiler display will show the following mes-

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
