Normally, the operation mode in the room where the unit is first run
is given priority, but the following situations are exceptions, so
please keep this in mind.
If the operation mode of the first room is
FAN Mode
, then using
Heating Mode
in any room after this will give priority to
heating.
In
this situation, the air conditioner running in FAN Mode will go on
standby, and the operation lamp will flash.
• COOL, DRY and FAN mode may be used at the
same time.
• AUTO mode automatically selects COOL mode or
HEAT mode based on the room temperature.
Therefore, AUTO mode is available when
selecting the same operation mode as that of the
room with the first unit to be turned on.
Otherwise, they will enter the Standby Mode, and the
operation lamp will flash; this does not indicate malfunction.
