• Read this manual carefully for correct installation of the wireless remote controller kit 

before starting work.

• After the installation is completed, execute a test run to check for normal operation 

and explain how to use and maintain the wireless remote controller kit to the customer 
according to the Owner’s Manual.

Ask the customer to keep this manual with the Owner’s Manual.

Observe the safety precautions described in the Owner’s Manual of the wireless 
remote controller kit, Installation Manual and Owner’s Manual of the 4-way cassette 
type air conditioner (indoor unit), or the installation manual supplied with the ceiling 
panel.

Accessories

Settings for the signal receiving unit before installation

Before installing the signal receiving unit, make the following settings referring to each 
description.
• To install the wireless remote controller together with wired remote controller

,

 

configure the “Multiple remote controller installation”

• When ceiling height exceeds the standard height (factory default), refer to the 

"Installing indoor unit on high ceiling" on installation manual of the indoor unit.

How to install the signal receiving unit

Install the signal receiving unit 
in correct orientation, since 
the signal receiving unit can 
be installed at only one corner 
as shown in (Fig. 1).

1.

Remove the air intake grille.

2.

Remove the adjust corner 
cap at the corner where the 
signal receiving unit is to be 
installed. (Fig. 2) 
Pull the knob of the adjust corner cap in the arrow 

1

 direction. Remove the adjust 

corner cap.

* The knob is provided only on one side of the cap. Be sure to detach the cap from the 

knob side.

3.

A pad is packed in the two rectangular holes (indoor unit side and signal receiving 
unit side) for ceiling panel wires. Remove the pads temporarily, and pass the wires 
from the wireless signal receiving unit through the rectangular holes. (Fig. 3)

4.

After the wiring is completed following “How to wire the signal receiving unit” below 
without slack of the wires, pull the black pad that covers the wire by approx. 20 mm 
out of the rectangular hole on the indoor unit side, and then clamp the wires with the 
supplied clamp tightened with the screw. Then return the packing removed from the 
rectangular hole on the signal receiving unit to the original position. (Fig. 3)

* Securely position the black pad and fix the packing. Failure to do so may cause water 

leakage or dew drop on the unit and wires.

Clamp

Remove the pad from the 
rectangular hole on the signal 
receiving unit side, clamp the 
wires with the clamp, secure the 
clamp with the M4 x 12 mm 
screw, and then return the pad to 
the original position.

Pull the black pad that covers the wire 
by approx. 20 mm out of the hole.

Remove the pad from the 
rectangular hole on the indoor 
unit side.

(Fig. 3)

5.

Attach the signal receiving unit to the ceiling panel, while taking care not to catch the 
wires. (Fig. 4)

• Push the three claws of the adjust corner cap firmly as far as they will go. Failure to 

do so may result in water leakage.

Note:

Do not bundle these control signal wires with the power wire to avoid 
malfunction.

How to wire the signal receiving unit

<Connection diagram>

<Connection>

Connect the wires from the signal receiving unit to the remote controller connection 
terminal block of the indoor unit. (The terminals are nonpolar.)
• Clamp the redundant portion of the wires with the clamps in the electrical control box.

Multiple remote controller installation

The control by two remote controllers is enabled by installing the wireless remote 
controller with the wired remote controller for an indoor unit.
(Max. 2 remote controllers of wireless or wired are insatiable.)
“2-remote controllers” controlling means that one or multiple units are operated by the 
multiple remote controllers.

Note:

1.

Upon confirmation of the terminal numbers of the indoor unit, connect the control 
wire without miswiring. (If applied 220 - 240 V, damage the unit.)

2.

The multiple wireless remote controller kits cannot concurrently be used for an 
indoor unit.

3.

When installing simultaneously the wireless remote controller with the wired remote 
controller, set one of them as the follower remote controller.
• To use wired remote controller or Lite-vision plus remote controller as a follower, 

settings must be changed. For the details, refer to the installation manual of each 
controller.

• To use the wireless remote controller as a follower, set bit 4 (Follower side) of DIP 

switch SW30 on the signal receiving unit P.C. board to ON.

2-remote controllers

The indoor unit is operated if either wireless or wired remote controller is set as header 
or follower remote controller.
(Total wire length: Within 400 m)

Rectangular holes

Claws

Insert the two claws on the adjust corner 
cap (with signal receiving unit) into the 
rectangular holes of the ceiling panel in 
the arrow direction.

Push the adjust corner cap in the arrow 
directions so that the three claws are 
fitted.

Remote controller address (A-B selection) setting

• When two or more signal receiving units are installed in a room, a unique address 

can be set for each signal receiving unit to prevent interference.

• Address (A-B selection) must be changed on both signal receiving unit and wireless 

remote controller.

• For the details of address change (A-B selection) on wireless remote controller, refer 

to the owner's manual.

Turn off the indoor unit power supply. Turn on the bit 4 of DIP switch SW30 on the 
signal receiving unit P.C. board.
The setting change is shown below.

Test run (Forced cooling operation)

Requirement:

• Finish the forced cooling operation in a short time because it applies excessive 

strength to the air conditioner.

How to perform forced cooling operation

1.

When TEMPORARY button is pushed for 10 seconds or more, “Pi!” sound is heard 
and the operation changes to a forced cooling operation. After approx. 3 minutes, a 
cooling operation starts forcedly.
Check cool air starts blowing. If the operation does not start, check wiring again.

2.

To stop a test operation, push TEMPORARY button once again (Approx. 1 second).

• Check wiring / piping of the indoor and outdoor units in forced cooling operation.
