9-2. Group Control Operation
In a group control, operation of maximum 8 indoor units can be controlled by a remote controller.
The indoor unit connected with outdoor unit (Individual/Master 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/Air volume select/Setup temp) of the indoor unit which was set to the
master unit is reflected on the remote controller.
2. Address setup
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 3 In/Out cables surely.
2) Check line address/indoor address/group address of the unit one by one.
3) The unit No. (line/indoor gout 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.
