Cable requirements
Procedure
1 Open the unit and put the switch box in front of the unit as
described in
"Opening the unit" on page 35 .
2 Open the switch box cover.
3 Using the appropriate cable, connect the power supply and
communication cable(s) to the appropriate terminals as shown
on the wiring diagram and according to
figure 3 .
4 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 figure 3 .
5 Close the switch box cover and install the switch box back into
the unit by following the instructions described in
"Opening the
unit" on page 35 in reverse order.

NOTE Select all cables and wire sizes in accordance with
relevant local and national regulations.
After finishing the electric work, confirm that each electric
part and terminal inside the electric parts box is connected
securely.
■
To avoid receiving electric noise, be sure that the
cables are put in the correct bundle and routed in
the correct bundle tray as shown in
figure 3 .
■
When wiring, route the cable bundles that are
outside the unit away from each other by at least
25 mm in order to avoid receiving electric noise
(external noise).
■
Be sure to route all cables between the unit side
plate and the wiring retention bar as shown in
figure 3 .
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.
