Fix the cables with cable ties to the cable tie mountings to
ensure strain relief and to make sure that it does not come in
contact with the piping and sharp edges. Never squeeze
bundled cables.
Note: only relevant field wiring is shown in
5
Close the switch box cover and install the switch box back into
the unit by following the instructions described in
in reverse order.
Installation of the remote controller
The unit is equipped with a remote controller offering user-friendly
way to set up, use and maintain the unit. Before operating the remote
controller, follow this installation procedure.
1
Remove the front part of the remote controller.
Insert a slotted screwdriver into the slots (1)
in the rear part of the remote controller, and
remove the front part of the remote
controller.
2
Fasten the remote controller on a flat
surface.
3
Wire the unit.
Connect the terminals on top of the front part of the remote
controller and the terminals inside the unit (P1 to X3M:P1, P2 to
X3M:P2).
4
Reattach the upper part of the remote controller.
First begin fitting from the clips at the
bottom.
Connection to a benefit kWh rate power supply
Electricity companies throughout the world work hard to provide
reliable electric service at competitive prices and are often authorized
to bill clients at benefit rates. E.g. time-of-use rates, seasonal rates,
Wärmepumpentarif in Germany and Austria, ...
This equipment allows for connection to such benefit rate power
supply delivery systems.
Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the benefit kWh rate
power supply delivery systems available, if any.
When the equipment is connected to such benefit kWh rate power
supply, the electricity company is allowed to:
■
interrupt power supply to the equipment for certain periods of
time;
■
demand that the equipment only consumes a limited amount of
electricity during certain periods of time.
The indoor unit is designed to receive an input signal by which the
unit switches into forced off mode. At that moment, the unit
compressors will not operate.
NOTE
The wiring for connection is not included.
■
The remote controller, delivered in a kit, has to be
mounted indoors.
■
When the remote controller thermostat function is
used, select the installation location considering it
should be a place:
-
where the average temperature in the room can be
detected,
-
that is not exposed to direct sunlight,
-
that is not near a heat source,
-
that is not affected by outside air or air draught due
to e.g. door opening/closing,
-
where the display is kept clean,
-
where the temperature is between 0°C and 50°C,
-
where the relative humidity is maximum 80%.
NOTE
Be careful not to distort the shape of the lower
part of the remote controller by over tightening the
mounting screws.
NOTE
If next to the standard remote controller the
optional remote controller is installed as well:
■
Connect the electrical wires of both remote
controllers in the same way like described
below.
■
Select a master and a slave remote controller
by switching the SS1 selector switch.
■
Only the remote controller set as master can
work as room thermostat.

Be careful not to pinch the wiring when attaching.
WARNING
For a benefit kWh rate power supply like illustrated
below as type 1
During the period that the benefit kWh rate is active and
power supply is continuous, then stand-by power
consumption of the inverter PCB is possible.
