Address selection display
If there are two indoor units installed in a room and if
they are to be operated independently of one another,
each unit must have its own address assigned so that it
can be operated with the correct remote control. This is
programmed as follows:
Address configuration of the unit
1. Press down the buttons (6) and (13) of the re-
mote control for five seconds.
The display is deleted. The time display shows the
first configuration entry “rAdr“, the temperature dis-
play shows the preset value of this configuration en-
try “Ab“ (regulation of both indoor units).
2. Press either the button (8) or (9) to change the
preset from “Ab“ to the new selection “A“ or “b“.
3. Press the button (13) to transfer the new configu-
ration to the unit and then press the button (7) to
exit the configuration menu.
Address configuration of the remote control
1. Press down the buttons (6) and (13) of the re-
mote control for 5 seconds.
The display is deleted. The temperature display
shows the first configuration entry “CH“, the time dis-
play shows the preset value of this configuration en-
try “Ab“ (regulation of both indoor units).
2. Press either the button (8) or (9) to change the
preset from “Ab“ to the new selection “A“ or “b“.

If no button is pressed for 30 seconds, the configu-
ration menu is automatically exited and program-
ming must be started from the beginning.
à
Keep the unit free of dirt, plants and other deposits.
à
Only clean the unit with a damp cloth.
à
Do not use an abrasive cleaning agent or one that
contains solvent.
à
If the unit is extremely dirty, only use suitable clean-
ing materials.
à
Clean the air filters of the indoor unit at regular inter-
vals, more often if necessary, in line with the operat-
ing instructions.
à
Before and after the operating season, check
whether the diameter of the condensation lines has
become smaller as a result of dirt.
If so, they must be cleaned.
à
We recommend concluding a maintenance agree-
ment with an authorised service centre.
This is the best way to guarantee that the unit is op-
erated safely!
Note:
Never operate the unit without the original filters. Other-
wise the heat-exchanger fins would become dirty and
the performance of the unit would suffer. Dirty fins are
difficult to clean.
G
Before any work on the units is performed, they
must be disconnected from the power supply and
prevented from being inadvertently switched on
!
Maintenance and Service
Regular care and the observation of a number of basic
rules will ensure the unit’s long service life and reliable
operation.
Cleaning the filter
Clean the air filter at intervals of no longer than 2 weeks.
If the air is extremely dirty, shorten this timeframe ac-
cordingly.
Proceed as follows to clean the filter:
1. First rotate both plastic cross-head screws on the
grating by 90°.
The air intake grille cannot fall out because it is sus-
pended on the other side and attached to the grating.
