5. Description of the operation modes
1 FAN ONLY OPERATION
In this mode, the air is circulated without being heated or cooled.
2 DRY OPERATION
In this mode, the air humidity will be lowered by intermittently
turning the air conditioner ON in cooling and OFF again to
minimise the temperature decrease.
The temperature and fan speed are controlled automatically
and cannot be controlled by the user interface.
Dry operation will not function if the room temperature is too
low.
3 AUTOMATIC OPERATION
In this mode, the user interface will automatically switch
between heating and cooling as required by the setpoint.
4 COOLING OPERATION
In this mode, cooling will be activated as required by the setpoint
or setback operation.
5 HEATING OPERATION
In this mode, heating will be activated as required by the
setpoint or setback operation.
6 SETBACK
The setback function will maintain the room temperature in a
specific range when the user interface is turned OFF. This is
done by temporarily starting the air conditioner that was
previously turned OFF by the user, the schedule function or the
OFF timer.
For example:
If the room temperature drops below 10°C, heating is started
automatically. If after half an hour the temperature increases
to 12°C or above, the user interface returns to its original
state.
If the room temperature goes above 35°C, cooling is started
automatically. If after half an hour the temperature decreases
to 33°C or below, the user interface returns to its original
state.
The differential can be adjusted in the setback menu. The
setback temperature can be set while the unit is turned OFF on
the basic screen, or can be set in the schedule.
The status of setback (enabled/disabled) can be seen in the
Energy Saving List.
By default, the setback function is disabled. Before enabling
it, first consult the detailed information about
SETBACK in the
user reference guide.

18. ʺMode Conflictʺmessage
Only applicable in case of a multi system (multiple indoor units
connected to the outdoor unit). When multiple indoor units are
instructed to operate simultaneously, but in different operation
modes, an operation mode conflict occurs:
The operation lamp flashes

MODE CONFLICT appears on the user interface
The units that do not have priority enter standby mode
This is not a malfunction. To solve the conflict, make the units that do
not have priority run in the same operation mode as that of the unit
that has priority. Which unit has priority depends on whether the
Priority Room setting is present and/or active:
19. Combined use of the wired and wireless user
interface
With icons With icons and text
If... Then...
The Priority Room setting is present
and active. The operation mode of the indoor unit to which the
Priority Room setting
is applied takes priority. In case of an
operation mode conflict, the other
units will enter standby mode.
NOTICE

COOL , DRY and FAN operation can be used
simultaneously.
If the conflict is not solved manually, non-priority units
will automatically resume operation as soon as the
priority unit stops operating.
It is NOT possible to enter the menu when the user
interface indicates the
MODE CONFLICT message.

If... Then...
The Priority Room setting is not present
OR present but not active. The operation mode of the indoor unit that was turned on first takes
priority. In case of an operation mode
conflict, the units that were turned on
later will enter standby mode.
NOTICE

COOL , DRY and FAN operation can be used
simultaneously.
Units running in
HEAT operation mode always have
priority over units running in
FAN operation mode,
even if they were not turned on first.
When solving the conflict, it is possible to make the
non-priority units run in
AUTO operation mode: they will
automatically start operation in the same operation
mode as that of the priority unit.
It is NOT possible to enter the menu when the user
interface indicates the
MODE CONFLICT message.
CAUTION
The
MODE CONFLICT can also happen to units that are
turned on by the
setback function. This means that due to
priority, they will not run and consequently will not be able
to maintain the temperature in the room. Please consider
the use of the
setback feature in a multi system carefully to
avoid situations like these.
CAUTION
Avoid using the wired user interface and the standard
wireless user interface at the same time.
When combining the user interfaces, refer to the user
reference guide for the phenomena that can occur.

is required.
The S21 connector is not present on some indoor units. In this
case, the KRP980 should be installed first.
4. Fasten the user interface
1Wall mounting, fasten with the 2 included wood screws
(Ø3.5×32) and plugs.
2Switch box mounting, fasten with the 2 included small
screws (M4×16).
For the field-supplied switch box, use optional accessory KJB111A or
KJB211A.
WARNING
Carefully read these instructions before installation. They
will tell you how to install, how to configure and how to use
the unit properly. Keep this manual in a handy place for
future reference.
This is an option to be used in combination with Daikin
units. Refer to the installer reference guide and user
reference guide of the units for installation and operation
instructions.
WARNING
All field wiring and components must be installed by an
installer and must comply with the applicable legislation.
NOTICE
When the thermo function of the user interface is used,
select the installation location while considering it should
be a place:
where the average temperature in the room can be
detected,
which is not exposed to direct sunlight,
which is not near a heat source,
which is not affected by the outside air or air draught
due to, for example, opening/closing of doors or the
like,
where the front panel and the display are kept clean,
where the temperature is between –10°C and 50°C,
where the relative humidity is max. 95%,
that is NOT located outdoors.
NOTICE
Do NOT install the user interface:
Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of
the control system and result in a malfunction of the
unit.
In moist areas or places where it may be exposed to
water. If water enters the user interface, electric
shocks may be caused and the inner electronics may
fail.
WARNING
Consult your local dealer regarding relocation and
reinstallation of the user interface.
