To connect the user interface

The unit is equipped with a user interface offering a user-friendly way
to set up, use and maintain the unit.

Before operating the user interface, follow this installation procedure.

Procedure

Remove the front part of the user interface

Insert a slotted screwdriver into the slots (1)
in the rear part of the user interface, and
remove the front part of the user interface.

Fixation of the user interface to the indoor unit

1 

Fix the wallplate of the user interface to the frontplate of the unit.
For installation of the frontplate, see 

"7.4.1. To fix the user

interface cover to the indoor unit" on page 16

.

2 

Cut off a 2 wire conductor.

3 

Connect the wires to the user interface as shown below.

From the rear

4 

Reinstall the faceplate onto the wallplate.
First begin fitting from the clips at the bottom.

5 

Remove the user interface cover from its hinge.

CAUTION

Do NOT push or place redundant cable length in the unit.

NOTICE

The wiring for connection is not included.

NOTICE

The user interface, delivered in a kit, has to be mounted
indoors.

NOTICE

The PCB is mounted in the faceplate of the user interface.

Be careful NOT to damage it.
