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
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:

operation can be used

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.
