When using a receiver that has been installed separately into the ceiling, use the plate 
mounting.

1.  Remove the face plate of the receiver by slipping a slotted screwdriver or the like into the cutout on the bottom.
2.  Cut out a hole in the ceiling to match the dimensions of the ceiling installaion pattern.
3.  Pass the wiring through the plate mounting and put it into the hole. (Fig. A)
4.  Bend parts A and B of the plate mounting so they hold onto the ceiling fi rmly. (Fig. B)
5.  Connect the receiver’s wiring (2 cores) with the wiring from the indoor unit.

(Refer to the chapter on wiring the receiver.)
When wiring receivers, be sure to double-check the terminal numbers of the indoor unit before connecting them so 
there are no mistakes in the wiring. (Damage will occur if high voltage [e.g. supply voltage] is applied.)

6.  Adjust the enclosed spacers so they are several millimeters thicker than the ceiling material and hold the receiver 

in place temporarily with the 2 enclosed small screws.

7.  Bend parts A and B back so they fi t in the opening and are in the gap between the surface of the ceiling and the 

receiver; then tighten the screws. Do not use too much force when tightening the screws. Doing so may warp or 
damage the case. Move the receiver by hand and check that it can move just a little. (Fig. C)

8.  Attach the face plate.

Wiring the Receiver

  Use wiring of AWG#20 – AWG#14 for fi eld supply.
  Use a total wire length of no more than 1300 ft.

 

Polarity does not matter.

1.  Strip the wire to be connected of its sheathing for 35/64 in.
2.  Twist the two wires together and crimp the enclosed wire joint.
3.  If a special crimping tool is not used, or if the connection is made using solder, 

wrap the joint with insulating tape.

Test Operation

Implementing a Test Run

1.  Remove the face plate of the receiver’s PCB and turn the DIP switch to RUN/On (Down 

 Up) and operate the 

wireless remote controller with its Start/Stop button.

2.  During a test run, all display lamps on the display will light up.
3.  During a test run, it is not possible to adjust the temperature.
4.  After completing a test run, be absolutely sure to return the Test Run switch to OFF (Up

 Down) and make sure 

none of the display lamps are blinking. Also, put the face plate back in place.

<Note 1>  This is hard on the device, so only use this for the test run.
<Note 2>  After turning on the power, the unit will not receive any commands from the remote controller for about 1 

minute. This is not an error. (In fact it does receive signals, but they are cancelled.

<Note 3>  Make sure to operate while the indoor unit is stopped.
<Note 4>  The address of indoor unit is set to “ALL” at the time of the shipment.

Setting Address Switches

  When more than one receiver and remote controllers are installed in the same room, setting up addresses allows 

them to avoid interfering with each other.

  Refer to the Operating Instructions for information on how to change the addresses of the remote controllers.
  Changing the address of a receiver can be done after removing the screw to the receiver’s PCB cover. Once the 

change is complete, put the cover back in place; while holding the wiring with the cable clamp, tighten its screw.


If it is to be used as an exposed model:

 

Wiring Diagram

<Note 1>  When wiring remote controllers, be sure to double-check the terminal numbers of the indoor unit 

connecting them so there are no mistakes in the wiring. (Damage will occur if high voltage [e.g. supply 
voltage] is applied.)

<Note 2>  If the wiring to the operation panel is bundled together with other wiring, such as the incoming line from 

the power source, it can cause a malfunction, so avoid doing so.

<Note 3>  If something causes the unit’s power source to make noise, it will be necessary to resolve the problem, 

such as by installing a noise fi lter.

Remote Control Wiring 
(Sold Separately)

  Use remote control wiring (sold separately) for wiring a separately installed receiver.

1.  For instructions on how to install a remote control wiring (sold separately), refer to the chapter on Using as an 

Embedded Model in Installing Separate Receivers.

2.  If a remote control wiring (sold separately) is to be used, refer to the Mounting Instructions attached to the remote 

control wiring.

Common to All Models

  The indoor unit and the wireless remote controller are equipped with 

indoor temperature sensors. The sensing of indoor temperature works 
via one of them.

  When the unit is shipped, it is set to the indoor unit, but to switch to 

the remote controller, press the sensor button (diagram at right) inside 
the remote controller’s cover and then check to make sure that Main 
Sensor on the LCD screen goes off.

<Note> 

Even when the sensor switch has been set to the remote 
controller, if the unit does not receive any room temperature 
data from the remote controller for ten minutes, it 
automatically switches back to the indoor unit sensor, so be 
sure to install the remote controller facing the receiver.

Setting Up Remote Control Functions

The functions of the wireless remote can be set on site.
(These settings are saved in nonvolatile memory in the remote controller, so even when its batteries are 
changed, the settings do not revert to the defaults.)

<Note>   The operation of the air conditioner can be impacted, depending on the settings made, so only service 

personnel should make the settings.

 

Furthermore, making changes to these settings may cause actual operation to deviate from what is 
printed in the Operating Instructions, so be sure to explain this to the customer fully.

Making Settings (Do with unit stopped.)

1.  Holding down the Swing/Wind Dir OFF Timer 

 + Mode Select buttons at the same time for 4 or more 

seconds makes the display switch to the setting screen. (See Diagram 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 settings display of the LCD 

changes from blinking to light.

5.  If other settings are to be changed as well, repeat steps 2 to 4.
6.  When all settings have been made, press the Start/Stop button.

Example: Operation mode setting screen

Note 1 

While the unit is in the swinging mode (Swing/Wind Direction), the fl ap cannot be stopped in a desired 
position.

Note 2 

When Setting OFF is selected, “°C” is displayed on the LCD screen.

Note 3 

You can toggle between ON and OFF by pressing Ventilation 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 refl 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.
