Connection to remote control
The remote control is supplied
as an accessory
-Remote On/Off CONNECTION
Remove the jumper of terminals 3-4 for the REMOTE ON/OFF command and connect the required electrical contact.
-REMOTE SUMMER/WINTER connection
Remove the jumper of terminals 1-2 for the REMOTE SUMMER/WINTER command and connect the required electrical con-
tact.
The parameter for enabling the instrument on the machine and/or the remote control is (par. H27), while for the ON/OFF and
S/W remote controls it is (par. H27=1)
Proceed in the following way to access parameter H27 and make the required configuration:
1.
Press the ON/OFF key and keep it depressed until the instrument comes on.
2.
Press the MODE and ON/OFF keys at the same time for one second. The word
Set
will appear.
3.
Repeatedly press the MODE key until
Par
appears.
4.
Press the MODE and ON/OFF keys at the same time and keep them depressed for at least one second until
Cnf
appears.
5.
Press the MODE and ON/OFF keys at the same time and keep them depressed for at least one second until H01 appears.
6.
Using the MODE key, select parameter H27 and configure it as needed.
7.
After having modified the parameter, repeatedly press MODE and ON/OFF until the initial mask returns.
Turn the unit off and on again with the main switch so as to reset the controller.
The machine is now ready to operate.
Wiring diagrams
The general wiring diaframs of the units are given on the following pages. These diagrams show the connections required for
powering the machine, activation of any supplementary loads (
pump
,
electric heating element
and the
alarm indicator
), con-
nection with the available digital inputs (
ON/OFF
, change of season
summer/winter
and connection with the
remote control
panel
).
All the connections must be made in compliance with the GENERAL REGULATIONS listed above.
ELECTRICAL CONNECTIONS
Electrical connections
ALL THE ELECTRICAL CONNECTIONS MUST BE MADE BY QUALIFIED PERSONNEL IN THE ABSENCE OF ELECTRIC
POWER. CONSULT THE “GENERAL SPECIFICATIONS” SECTION FOR THE ELECTRICAL SPECIFICATIONS OF THE
UNITS.
A- UNIT
- Electric power line
The machine’s power line should be routed in compliance with the current standards governing the classification of the places
in which they are installed. The machine’s power line should follow a precise route so that it is as short as possible and unbro-
ken. Proceed in the following way in order to carry out this operation:
-open the front panel of the unit.
-Route the powering line inside the unit (Fig. 1-A) through one of the holes in its structure (Fig. 1-B).
-Allow the line to pass into the compressor housing until it reaches the switch
(Fig.1-C). Remove the protective cover (Fig. 1-D) to access the switch.
Additional connections to make in the installation site
The electric panel is fitted with additional terminal boards for use if accessories controlled directly by the controller must be
installed.
The following table lists the codes and meanings of the various terminals, along with their respective functions and characteri-
stics:
