(c) Minimum cable section 0.75 mm
(d) This device and connection cable is delivered with the domestic hot water tank.
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.
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.
■
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.

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.

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.
The wiring for connection is not included.
NOTE
■
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:
(c)
- where the average temperature in the room can be
detected,
(c)
- that is not exposed to direct sunlight,
- that is not near a heat source,
(c)
- that is not affected by outside air or air draught due
(c)
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%.
(c)
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.
Be careful not to distort the shape of the lower
NOTE
part of the remote controller by over tightening the
mounting screws.
3 Wire the unit.
NOTE If next to the standard remote controller the
optional remote controller is installed as well:
