Select all cables and wire sizes in accordance with
NOTE
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.
Procedure
1 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
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
When wiring, route the cable bundles away from
each other by at least 25 mm in order to avoid
receiving electric noise (external noise).
2 Fix the cable 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

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%.
Be careful not to distort the shape of the lower
part of the remote controller by over tightening the
mounting screws.
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.
