ACCESSING THE ELECTRICAL PANEL
The electrical panel is located inside the unit at the top of the technical compartment where the various components of
the refrigerant circuit are also to be found.To access the electrical panel, remove the front panel of the unit by undoing
the metric screws. To access the components in the electrical panel and the terminal boards, undo the screws and re-
move the part of the panel.
Conduits containing live wires, even when the door lock disconnecting switch is off
ELECTRICAL POWER CONNECTIONS
For the functional connection of the unit, bring the power
supply cable to the electrical panel inside the unit and
connect it to terminals U-V-W N and ,
VW) phases, (N) neutral and (
AUXILIARY CONNECTIONS
All terminals referred to in the explanations below are to
be found on the terminal board inside the electrical panel
and described as "installer terminals".
REMOTE START UP AND SHUT DOWN
To be able to use a remote switching on and off device, a
switch must be connected to terminals 13 and 14 of the
installer terminal block. For timed operation, connect a
daily or weekly timer between terminals 13 and 14 (see
wiring diagram). Select the parameter H07 from the con-
trol panel HSW8 and put it to the value 1.
REMOTE HEATING/COOLING CONTROL
To fi t a remote heating/cooling selector, the jumper must
be replaced with a switch connected to terminals 11 and
12 on the installer terminal board. To activate the com-
mand, proceed as follows:
- Select the parameter H06 on the HSW8 control panel
and set it to 1.

REMOTE ALARM
For remote display of unit shut-down due to malfunction,
an audible or visual alarm warning device can be con-
nected between terminals 19 and 20. Connect the phase
to terminal 20 and the alarm signal device between ter-
minal 19 and the neutral (see wiring diagram).
REMOTE KEYBOARD KIT
The remote keyboard kit can be used to display all unit
functions and access the parameters of the electronic
board from a point located at some distance from the
unit itself.
To install the kit, follow the instructions accompanying
the kit.
To avoid interference due to magnetic fi elds, the
use of shielded cable is recommended.The ca-
ble should not be more than 100m long.
CONNECTING A FLOW SWITCH
The persons responsible for installing and commissio-
ning the unit must also fi t a fl ow switch. The fl ow switch
must be connected to terminals 9 and 10 of the fi tter ter-
minal block after removing the electric jumper (see wi-
ring diagram).
COMPRESSOR ON SIGNAL
If the operation of the compressor needs to be signalled
in a remote position, terminals 17 and 18 can be con-
nected to an audible or visual signal device. Connect the
phase to terminal 18 and the signal device between ter-
minal 17 and the neutral.
