unit. Face the transmitter of the controller toward the receiver of the indoor unit and press the
switch of required operation so that commands (by infrared rays) are sent to the indoor unit. The
distance for transmitting is approximately 6 meters as a maximum. (The capable distance for
transmitting will get shorter in case that the transmitting angle is not vertical to the receiver or an
electronic type light is used in the room, etc.).
Transmitter
Point the transmitter towards the receiver of the indoor unit when
sending commands. The Transmitting indication on the liquid crystal
display flashes when sending commands.
Transmitting Indication
Liquid Crystal Indication
The set temperature, timer operation, position of air louver,
operation mode, air flow mode, etc.. are indicated.

5 SENDING COMMANDS FROM CONTROLLER
The operation commands are sent by
pressing the required operation switch
by facing the transmitter of the controller
toward the receiver of the indoor unit.
1 When the commands are sent, the
'
' indication on the liquid crystal
display of the controller flashes once.
2 The indication lamp (yellow) on the
receiver part of the indoor unit turns
ON for an instant when the indoor unit
receives the commands.
Ô
ATTENTION:
- In case that the indication lamp (yellow) does not turn ON although the commands are sent,
the commands are not received by the indoor unit. In such a case, send the commands again.
- The transmitter of the controller has the vertical directivity to the receiver, and the permissible
angle for transmitting is within 50º. However, the capable distance for transmitting gets half
when the transmitting angle is 50º, and also get shorter in case that an electronic type light is
used in the room.
NOTE:
The above figure shows the case of a 4-way cassette type indoor unit. The figures for other
models are different partially.
LCD (Liquid Crystal Display) Indication
When viewed from certain angles the LCD can be difficult to
read.
The viewing angle ranges from an optimal of 60º down to 30º,
as shown in the diagram on the right.

6 OPERATION
When operating the controller, face the transmitter toward the receiver of the indoor unit and
press the switch for the required operation as described in the item '4. Sending Commands from
Controller'.
Ô
ATTENTION:
In case that two indoor units are installed side by side, the commands from the controller may
be received by both indoor units. The function to identify each indoor unit not applicable.
7 INSTALLING ONTO THE WALL OR PILLAR
Ô
ATTENTION:
When the commands are sent by the controller hooked onto the wall, the receiver of the indoor
unit may not receive the commands.
1) Select the suitable place for handling and install the controller with the customer's acceptance.
Do not install the controller at the places as shown in the below.
*where children can touch
*where the air from the air conditioner is directly discharged
*where there is oil vapor and the oil is dispersed
*where the humidity is high
2) Pay attention to the following points in case that the controller is installed in a place where there is
medical equipment radiating electromagnetic waves.
a) Install the controller in a place where electromagnetic waves are not radiated directly toward
the electrical box of the indoor unit and the controller.
b) Keep a distance more than 3 meters away from the equipment radiating electromagnetic
waves, the receiver of the radio, etc. for prevention of the noise through the air.
c) In case that there is electric noise at the power source for the indoor unit, the treatment such
as providing a noise filter is required.
3) Do not install the controller in a place where generation, flowing, staying or leaking of flammable
gas is detected.
4) Install the controller in a place where there is a distance more than 30cm from the power supply
cable when installing the controller onto the wall.
5) Install the holding bracket (accessory) onto the wall by using screw (accessory) and attach the
controller to the holding bracket. Test Running by Controller

switch.
1) Perform the test run after the installation work is completed.
a) Set the batteries for the controller.
b) Turn ON the power supply for the indoor and outdoor units.
c) '
' lamp (yellow) on the receiver of the indoor unit flashes (0.25 seconds ON 0.25 seconds
OFF), and then turns OFF. While the lamp is flashing, the unit will not operate because it is
initialising.
2) Set the test run mode by pressing 'SET' and
'OFF TIME' switch simultaneously for more
than 3 seconds. The LCD should be as

9 SIMULTANEOUS OPERATION OF MULTIPLE INDOOR
UNITS
The multiple indoor units (Max. 16 units) can be
started and stopped simultaneously by one controller.
Perform this operation only in case that multiple
indoor units are installed in a room as shown in the
figure.
CAUTION:
Do not perform this operation in case that the
multiple indoor units are installed in different
rooms separately. It may happen that some
indoor units remain unchanged
Procedures
Ô
ATTENTION:
Turn OFF all the power source before the following procedures such as wiring, setting the
rotary switch, etc.
1) Installation of Air Panel for Wireless Control
In case of simultaneous operation of plural (up to 16) units by the wireless remote control switch,
apply the air panel for wireless control only to the unit to be operated, and apply the standard
panels (for wired control) to other units. In case of applying plural air panels for wireless control,
up to 2 air panels for wireless control can be used.
In case of applying two (2) air panels for wireless control, the setting of main and sub receiver part
is required. Refer to the receiver kit installation manual.
2) Perform wiring between indoor units by referring to the receiver installation manual.
3) Fix the connecting control cable (do not use the white cord of the 3-core cable) between indoor
units at certain points with bands not to run along the power supply cable inside of the indoor unit.
The same wiring is required outside of the indoor unit; keep a distance more than 30cm between
the control cable and the power supply cable, or ground one end of a conduit tube after inserting
the control cable in the metal conduit tube.
