2 Receiver controlling the signal of the electricity company
3 Benefit kWh rate power supply
4 Voltage free contact to indoor unit
5 Normal kWh rate power supply
6 Fuse (field supply)
In case of benefit kWh rate power supply installation,
remove the wiring bridges on X2M before installing the
normal kWh rate power supply.
When the indoor and outdoor unit are connected to a benefit kWh
rate power supply, the voltage free contact of the receiver controlling
the benefit kWh rate signal of the electricity company must be
connected to clamps 7 and 8 of X3M (as illustrated in the figure
above).
When parameter [6-04]=1 at the moment that the benefit kWh rate
signal is sent by the electricity company, that contact will open and
the unit will go in forced off mode
When parameter [6-04]=2 at the moment that the benefit kWh rate
signal is sent by the electricity company, that contact will close and
the unit will go in forced off mode
(1) When the signal is released again, the voltage free contact will close and the unit
will restart operation. It is therefore important to leave the auto restart function
enabled. Refer to field setting "[8] Option setup, [8-01]" in the chapter
settings" on page 18.
(2) When the signal is released again, the voltage free contact will open and the unit
will restart operation. It is therefore important to leave the auto restart function
enabled. Refer to field setting "[8] Option setup, [8-01]" in the chapter
settings" on page 18.

TART UP AND CONFIGURATION
The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user expertise.
It is important that all information in this chapter is read

configured as applicable.

Pre-operation checks

Switch off the power supply before making any
connections.
After the installation of the unit, check the following:
1 Field wiring
Make sure that the field wiring has been carried out according to
the instructions described in the chapter
on page 13, according to the wiring diagrams and according to
European and national regulations.
2 Fuses and protection devices
Check that the fuses and other locally installed protection
devices are of the size and type specified in the chapter
"Electrical specifications" on page
fuse nor a protection device has been bypassed.
3 Earth wiring
Make sure that the earth wires have been connected properly
and that the earth terminals are tightened.
4 Internal wiring
Visually check the switch box and the inside of the unit on loose
connections or damaged electrical components.
5 Installation
Check that the unit is properly installed, to avoid abnormal
noises and vibrations when starting up the unit.
6 Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
7 Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
8 Water leak
Check the inside of the unit on water leakage. In case there is a
