Function and Control

Mode Conflict

[Overview]
While the indoor unit for another room and the outdoor unit are operating, when the indoor unit
for the own room is activated, the operation mode which can be selected in the own room has
some restrictions as mentioned below.
i)

In case an priority for operation mode selection is given to the own room by setting the dip
switch of outdoor unit;

→

The own room can be operated in any mode.

ii)

In case an priority for operation mode selection is not given to the own room by setting the
dip switch of outdoor unit;

→

The unit can be operated as follows:

:Operational

∗:

The unit for another room is switched into non-operational condition.

×

: Non-operational

* Operation of the indoor unit for the own room during non-operation.
•

Fan = OFF

•

Louver = becomes horizontal position.

•

ON LED on the remote controller = blinks.

•

Indication of "under central control" on the remote controller = displayed.

Note): During automatic operation, at the time of changing operation mode to Automatic cooling

or Automatic heating, the unit is operated as the table shown above.
