This mark indicate procedures which, if improperly performed, are most
WARNING!
likely to result in the death of or serious injury to the user or service personnel.
CAUTION!
This mark indicates procedures, which might result in personal harm to
the user or damage to property if improperly performed.
WARNING!
• Do not attempt to install this controller by yourself.
• This controller contains no user-serviceable parts. Always consult authorized service personnel for repairs.
• When moving this controller, consult authorized service personnel for disconnection and

Please consult your sales representative when two or more central remote controllers need to be
installed in one system.
• What is the central remote controller?
The central remote controller allows all the stored remote controller groups (the indoor units) to
be controlled from a remote location.
(Refer to “2-3. EXPLANATION OF TERMS 1” for details about remote controller groups.)
• Three functions of the central remote controller
• CENTRAL CONTROL
The central control provides management of the remote controller groups (the indoor units).
This includes placing restrictions on the standard remote controllers or performing memory operation for easily reproducing operating conditions that have been saved.
• OPERATION CONTROL
The operation control provides a controlled operation (such as the to stop operation) of the stored
remote controller groups (the indoor units) in the same manner as the standard remote controller.
• TIMER CONTROL
The timer control allows the starting and stopping of stored remote controller groups and indoor
units through the timer functions in the central remote controller. These timer functions include:
the off timer, on timer 1, on timer 2 and weekly timer.
3
• Three control methods of the central remote controller
• Individual control
2. SYSTEM OUTLINE
Provides control for each respective remote controller group.
• Group control
Provides control for each group which is made up of single or multiple previously set remote
control groups.
(Refer to “2-3. EXPLANATION OF TERMS” for details about groups.)
• All control
Provides control for all remote control groups that haven been stored in the central remote controller.

When a HEAT PUMP TYPE oper ating system is used, the system can only be performed
in one of two operation modes (cooling / heating) for single refrigerant system. When an
indoor unit in the system first starts an heating operation, the system is then in “heating
priority”. This means the system will refuse a command for changing the operation mode.
On the other hand, when an indoor unit in the system first starts a cooling operation, the
system is then in “cooling priority”. The system will refuse to change to any other operation
mode, except f or the drying operation.
will appear on the LCD when the indoor units associated with the selected

2-4. PRECAUTIONS WHEN SETTING THE SYSTEM
2-4-1. Priority of remote controller setting
2. SYSTEM OUTLINE
The most recent control transmission has priority. In other words, if two controllers (standard remote controller, central remote controller) send different control command to one indoor unit, it is
the last transmission that will have priority and be used by the indoor unit.
(Example) If the indoor unit is operating at a setting of 25 °C using a command from central remote
controller 1 and receives a command to operate at a setting of 20 °C from central remote controller
2, the indoor unit will operate at the setting of 20 °C.

2-4-2. Group information store
The following show the restrictions on group information store.
• A maximum of 64 groups can be formed in one system.
• A maximum of 64 remote control groups can be stored per group.
• Since the remote control group is the smallest control unit and can not be broken up, the
group must be made up with complete remote control groups.
The following show examples of group formation. There are some restrictions on operating
mode, on display for the following occasions.
• Group formed with the indoor units in two refrigerant systems.
When part of indoor units exist in cooling & heat pump type refrigerant system, certain operating
mode of the group can not be carried out even if the operating mode is shown on the LCD. In
addition, the operating mode is limited owing to cooling / heating priority setting.
• Overlapping groups.
The operating condition of the indoor units overlapped in the group is determined by the control
signal last sent to indoor units.

2. Turn on the power for all connected outdoor units.
3. Turn on the power for all connected central remote controllers.
Wait f or one min ute or more after turning on the power bef ore perf orming the initialization shown in
“3-2-2. Initial setting”.
3-2-2. Initial setting
The initial settings are performed by the initial setting mode. This is the required setting mode when
performing operation using the central remote controller. Initial setting mode is started under the
following conditions .
• When the power for the central remote controller is turned on for the first time.

(3)Indoor unit storing
The following are the three methods f or storing the remote control group with the central remote
controller. Select any one of them. However, the these storing menus will not be displayed
unless the system information scanning has been completed.
• Automatic storing
This automatically stores the remote control group with the central remote controller . Storing of all
remote control groups connected by communication cab le is performed automatically in ascending order of the refrigerant system addresses and indoor unit addresses.
• Manual storing 1
A remote control group can be optionally stored to a central control number. Here , the refrigerant
system addresses and indoor unit addresses are specified and stored one at a time to selected
central control numbers.
• Manual storing 2
The remote control group is stored in sequence of the standard remote controllers as they are
operated. Sending the refrigerant system address and indoor unit address of the remote control
group actually operated to the central remote controller performs the storing.
