To secure better effect of
heating
When it is difficult to obtain satisfactory heating due
to installation place of the indoor unit or structure of
the room, the detection temperature of heating can be
raised. Also use a circulator, etc. to circulate heat air
near the ceiling.

Group control

(Group control operation)
In a group control, operation of maximum 8 indoor
units can be controlled by a remote controller.
Twin, triple or double twin of an outdoor unit is one of
the group controls.
The indoor unit connected with outdoor unit (Individual/
Header of twin) controls room temperature according
to setting on the remote controller.
<System example>

1. Display range on remote controller
The setup range (Operation mode/Fan speed
select/Setup temp) of the indoor unit which was
set to the header unit is reflected on the remote
controller.
2. Address setup
If there is no serial communication between indoor
and outdoor when the power is turned on, it is
judged as follower unit of the twin. (Every time when
the power is turned on)
The judgment of header (wired) / follower (simple)
of twin is carried out every time. It is not stored in
nonvolatile memory.
Turn on power of the indoor unit to be controlled in
a group within 3 minutes after setting of automatic
address.
If power of the indoor unit is not turned on within 3
minutes (completion of automatic address setting),
the system is rebooted and the automatic address
setting will be judged again.
1) Connect indoor/outdoor connecting wire surely.
2) Check line address/indoor address/group
address of the unit one by one.
Especially in case of twin, triple, double twin,
check whether they are identical system address
or not.
3) The unit No. (line/indoor group address) which
have been set once keep the present status as
a rule if the unit No. is not duplicated with one of
another unit.
