Installation Location for the Reciver

The wireless remote controllers use a very weak infrared light for its signal, which can result in the signal
not being received because of the following inuences, so take care in where the unit is installed.
• Inverter or rapid-start type uorescent lights (Models without glow lamps)
• Plasma display or LCD televisions
• Direct sunlight or other sources of bright light
Attention

Multiple wireless remote controllers cannot be used simultaneously for a single indoor unit.

Be careful not to connect cables to other terminals of indoor units (e.g. power source wiring terminal).
Malfunction may occur.

Do not bundle together with the power source wiring or store in the same metal tube. Operation error may
occur.

If noise is induced to the unit power supply, attach a noise lter.
Installation when setting Main/Sub for the remote controller and the receiver
After installation, according to the “Settings” section, set one to [Main] and the other to [Sub].
Setting the wired remote controller to [Main] is recommended.
The remote controller and the receiver can be connected to any indoor unit for operation.

<Note 1> While the unit is in the SWING mode (swing/ap), the ap cannot be stopped in a
desired position.
<Note 2> When Setting OFF is selected, “°C” is displayed on the LCD.
<Note 3> You can toggle between ON and OFF by pressing ventilation “( ) button” for 4 seconds
or more.
<Note 4> If the Heater Max ON/OFF setting is not changed to EP (ON), the setting change will
not be reected.
<Note 5> This is the number of addresses that can be set in the address change mode. Do not
set it to 07 or above.
Preparation:
Turn on the circuit breaker of units and then turn the power on. After the power is turned
on, remote controller operation is ignored for approx. 1 minute because setting is being
made. This is not malfunction. (Contents received while setting are disabled.)
1. To start test operation, press and hold the emergency operation button for 10 seconds.
2. The indication lamps (OPERATION, TIMER, STANDBY) blink during test operation.
3. To nish test operation, press and hold the emergency operation button for 10 seconds.
Attention
Do not use this mode for purposes other than
the test operation.
(To prevent overload of the units)

Read the installation instructions supplied with the units.
Any of the Heat, Cool and Fan operations can
only be performed.
Temperature cannot be changed.
The test operation mode is automatically
turned o in 60 minutes.
(To prevent continuous test operation)

Outdoor units do not operate for approx. 3
minutes after the power is turned on or
operation is stopped.
1-7. Test Operation
When more than 1 receiver is installed in the same room, setting addresses prevents
interference.

For how to change addresses of wireless remote controllers, see the operating instructions of
wireless remote controllers.
 To change the receiver’s address, remove the cover from the receiver’s PCB and set No.1 to
No.3 of the [003] DIP switch on PCB.

1-9. Room Temperature Sensor Settings
The indoor unit and the wireless remote controller are equipped with
room temperature sensors. The sensing of room temperature works
via one of them.
When the unit is shipped, it is set to the indoor unit. To switch it to the
remote controller, press the sensor button (the gure on the right)
inside the remote controller’s cover and then check that Main Sensor
on the LCD screen goes o.
<Note> Be sure to install the remote controller so as to face the
receiver.
If the unit does not receive any room temperature data from
the remote controller for ten minutes even with its sensing
function activated, the indoor unit sensor will automatically
start sensing the room temperature.

1-10. Setting Up Remote Controller Functions
The functions of the wireless remote controller can be set on site.
(These settings are saved in nonvolatile memory in the remote controller. Therefore, the settings
do not revert to the defaults even when its batteries are changed.)
<Note> Only service personnel should make the settings because the operation of the air
conditioner may be aected, depending on the settings made.
Furthermore, making changes to these settings may cause actual operation to deviate
from what is printed in the Operating Instructions, so be sure to fully explain this to the
customer.
Making Settings (Do with unit stopped)
(1) Holding down the swing/ap ( ) + OFF timer ( ) + mode select ( ) buttons at the
same time for 4 or more seconds will open the setting screen. (See gure below.)
(2) Use the Temperature setting buttons / ( ) to select the number of the item to be set.
(3) Use the ON timer buttons / ( ) to change settings.
(4) The settings are saved with the once/every day button ( ). When this is done, the SET
displayed on the LCD changes from blinking to lighting.
(5) If other settings are to be changed, repeat steps (2) to (4).
(6) When all settings have been made, press the start/stop ( ) button.

Installation location for the Wireless Remote Controller

If a remote controller is to be operated from a remote control holder that is hung on a wall, turn on the lights in
the room as well as any electrical appliances and then check to make sure the air conditioner works with the
remote controller in the location where it will be installed. If it works, continue with installation.

If the main sensor is to be switched from the indoor unit to a remote controller, pay attention to the following
when installing.
• Locate where no warm or cold air will aect it.
• Locate in a place free from direct sunlight.
• Locate where it will not be aected by any other heat/cold source.
