How to Connect the Wires

Connect the wires from the receiver to the terminals for RC wiring on the indoor unit. (No polarity)

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.

*Wiring shown below is prohibited.

1-5. Installing the Receiver

1 Open the air inlet grill on the side panel. Remove the 1 screw and move it toward the front

(in the direction of an arrow) to remove it. (Fig. A)

2 Wrap the tip of a slotted screwdriver with plastic tape and then insert it under the O-marked

surface of the cover, wiggling the cover free. (Fig. B) (Be careful not to scratch the panel.)

3 After passing the lead wire through the panel, install the receiver in the hole in the panel.

(The projecting parts of the receiver is held in the hole in the panel.)

4 Fasten the receiver’s lead wire to the cable clip that is holding the wire from the louver motor.

(Fig. C)

5 Attach the side panel. 6 Put the receiver’s lead wire together with other wires such as the louver motor wire, and fasten

them with the cable clip. (Fig. D)

Use the hole in the upper part of the wiring box to lead it in.

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

1-7. Test Operation

Preparation:

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.

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.)

 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.

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 (3) Use the ON timer buttons

/ ( ) to change settings.

/ (

(4) The settings are saved with the once/every day button (

) to select the number of the item to be set.

). 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.

Installing Wireless Remote Controller

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.
