18. ʺMode Conflictʺ message
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
Mode conflict
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:
If...
The Priority Room setting is present
and active.
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.

Then...
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.
If...
The Priority Room setting is not present
OR present but not active.
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.
19. Combined use of the wired and wireless user
interface
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.
Then...
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.
