PRECAUTIONS
1. SAFETY PRECAUTIONS
• Before using CENTRAL REMOTE CONTROLLER, read this “SAFETY PRECAUTIONS” thor-
oughly to ensure the correct operation.
• This section discribes the important safety information to operate CENTRAL REMOTE CON-
TROLLER.
• The meanings of “WARNING” and “CAUTION” are explained as follows.
WARNING!
This mark indicate procedures which, if improperly performed, are most
likely to result in the death of or serious injury to the user or service per-
sonnel.
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 per-
sonnel for repairs.
• When moving this controller, consult authorized service personnel for disconnection and
installation.
• If the problem (burning, smell, etc) occurs, turn off the electrical breaker immediately to
stop operation and then consult the authorized service personnel.
• If the power supply cord becomes damaged, contact your service representative for in-
struction.
CAUTION!
• Do not expose the controller directly to water.
• Do not operate the controller with wet hands.
• Do not touch the switches with sharp objects.
• Always turn off the electrical breaker whenever cleaning the controller, the air conditioner
or the air filter.
• Ensure that all electronic equipment is at least one meter away from the controller.
• Avoid installing the controller near a fireplace or other heating apparatus.
• When installing the controller, take precautions to prevent access to infants.
• Do not use inflammable gases near the controller.
• At the time of installation, always provide a breaker for electrical leakage.
• Always use fuses with the proper capacity and type.

2-1. SYSTEM OUTLINE
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 op-
eration 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 control-
ler.
• 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.

Cooling / Heating priority:
When a HEAT PUMPTYPE operating 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 for 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. SYSTEM OUTLINE
2-4. PRECAUTIONS WHEN SETTINGTHE SYSTEM
2-4-1. Priority of remote controller setting
The most recent control transmission has priority. In other words, if two controllers (standard re-
mote 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.
This applies when performing separate operations from different controllers.
Central remote controller ⇔Standard wired remote controller or Central remote controller 1 ⇔
Central remote controller 2.
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.

3-2-1. Turn on power
Once the installation and wiring has been completed, use the following procedure to turn on the
power.
1. Turn on the power for all connected indoor units.
2. Turn on the power for all connected outdoor units.
3. Turn on the power for all connected central remote controllers.
Wait for one minute or more after turning on the power before performing 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.
• When SW42 on the control circuit board is pressed.
How to remove the case top of the control
panel.
• Insert a flap-tip screw driver and turning
it to remove the cover.
When the power is turned on for the central remote controller for the first time, initial setting mode
automatically starts so that the initial settings for the central remote controller can be performed.
These settings are performed using the following procedure.
1. Central remote controller address settings.
2. System information scanning
3. Storing the remote controller group to central control number.
• Automatic storing.
• Manual storing 1.
• Manual storing 2.
Press between each setting to change.(Refer to the next page.)
