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 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 and weekly timer.

• Three control methods of the central remote controller

• Individual control

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 have been stored in the central remote controller.

2. SYSTEM OUTLINE

2-2. FEATURES

The front panel of the remote controller can be divided by function into three different control areas.

2. SYSTEM OUTLINE

CENTRAL CONTROL The central control provides management of indoor units. This includes placing restrictions on the standard

remote controllers or performing memory operations.

If multiple remote control groups are set as one group,the control of these remote control groups can be realized by simply choosing the group.

Cooling / Heating priority:

When a HEAT PUMP TYPE 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.

• 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.

Refrigerant system 1

Refrigerant system 2

• 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.

Notes * Cannot be set in HEAT PUMP TYPE refrigerant system.

** Cannot be set in COOLING ONLY TYPE refrigerant system. When a group is comprised of indoor units which are in different types of refrigerant systems (HEAT RECOVERY TYPE / HEAT PUMP TYPE / COOLING ONLY TYPE), it is still possible to do an operating mode setting for the group. However, the newly set operating mode will be conducted only by those remote control groups in the group, when the newly set operating mode can be conducted by them. When a heating operation mode is attempted on a cooling only type refrigerant system, the central control number will flash and the set operating mode will not be conducted. This occurs when a group comprised of indoor units with different types of refrigerant systems (heat recovery type / cooling & heat pump type / cooling only type). Actually, the operating command is sent to the relevant indoor units, but the command will not be conducted by those indoor units when the set operating mode is not permitted by the type of refrigerant system where they exist.

• If the mode automatically selected by the unit is not satisfactory, see above and change the mode setting (COOL , FAN).

AUTO (AUTO CHANGE OVER) ..HEAT&COOL MODEL (Reverse cycle)

• When AUTO CHANGE OVER is selected, the air conditioner selects the appropriate operating mode (Cooling or Heating) according to the real room temperature.

• When AUTO CHANGE OVER is first selected, the fan will operate at very low speed for about one minutes while the unit determines the current conditions of the room and accordingly selects the proper operation mode.

• When the air conditioner has adjusted the room temperature to near the thermostat setting, it will being monitor operation. In the monitor operation mode, he fan will operate at low speed. If the room temperature subsequently changes, the air conditioner will select the appropriate operation (Heating, Cooling) once again to adjust the temperature to the value set with the thermostat. (The monitor operation range is ±2 °C relative to the thermostat setting.)

• If the mode automatically selected by the unit is not satisfactory, see above and change the mode setting (HEAT, COOL, FAN).

• Do not select AUTO CHANGE OVER if the difference in the environmental temperature of the master and slave units is over 2 °C. (Otherwise, the indoor fan may not be controlled correctly.)

About the AUTO setting of fan speed

Heating: Fan operates so as to optimally circulate warmed air. However, the fan will operate at very

low speed when the temperature of the air issued from the indoor unit is low.

Cooling: As the room temperature approaches that of thermostat setting, the fan speed becomes

slower.

Fan: The fan alternately turns on and off; when the fan turns on, it rotates at a low fan speed.

• The fan will operate at a very low speed during the monitor operation by which the room temperature is deleted.

6. TIMER SETTING

The timers built in the central remote controller have four different operating modes. They are shown as the following and can be selected only one from the four modes.

• OFF TIMER ........... Stop the indoor units at the set time.

• ON TIMER ............. Start the indoor units at the set time.

• WEEKLY TIMER .... Weekly timer setting function. Up to two on / off settings for each day of the

week. (Refer to 6-3. WEEKLY TIMER)

Notes Timer settings in multiple locations

• If the on timer setting is also performed by the standard remote controller, the standard remote controller timer will have priority. (If there is an on command from the central remote controller to the indoor units, the indoor units will not start to operate.)

• If timer settings are performed simultaneously at central remote controllers at multiple locations (central remote controller 1, central remote controller 2,...), the indoor units will follow the command of the central remote controller that the last control signal will send out.

Stop timer operation

• An electricity failure will cancel all set time. The setting will become non stop setting.
