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.

as well as the control unit of a single indoor unit that has not been connected with any
controller line.
These two kinds of control units are the smallest unit controlled by central remote controller, and are called a remote control group.
Group:
This is a control unit comprised single or multiple remote control groups.
All:
This is a control unit of all remote control groups that have been stored in the central
remote controller.
Refrigerant system:
This is a system that is composed of indoor units, outdoor unit as well as those of
relevant control equipment. All of the units and the equipment are connected with pipes
with the same refrigerant.

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
central control number exists in cooling / heat pump type refrigerant system.

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.
