INSTALLATION MANUAL

To Personnel Charged in Installation Work and Service

Wireless remote controller kit
Model: TCB-AX32E2

EB01800301 (EN)

• Thank you for purchasing Wireless remote controller kit TOSHIBA packaged air 

conditioner.

• 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 indoor unit.

Accessory Parts

Installation Location of Signal Receiving Unit

• Do not install in a location where the air contains oil mist, such as in a kitchen or 

factory.

• Do not install next to a window, or in any other location directly exposed to sunlight 

and outside air.

• Do not install nearby devices which can be expected to produce electrical noise, 

such as elevators, automatic doors, and industrial sewing machines.

• If the Signal receiving unit is installed near a rapid-start type or inverter-type 

fluorescent lamp (a lamp which does not include a glow lamp), it may not be 
possible to receive the wireless remote controller signal in some cases. In order to 
prevent interference from fluorescent lamps, leave a minimum of 2 m between the 
Signal receiving unit and the fluorescent lamps, and install the Signal receiving 
unit in a location where it can receive the wireless remote controller signal when 
the fluorescent lamps are lit.

How to Install the Signal Receiving Unit

To prevent electric shocks, embed the wires in the wall and do not expose them.
When installing wires on the wall, be sure to cover them with insulating materials.

Note:

• To avoid malfunction of the remote controller, do not assemble or run remote 

control wiring together with the power cables, and do not enclose them in the 
same metal conduit.

• When the power unit induces electrical noise, it is recommended that a noise filter 

or the like be installed.

Installing into the switch box

1.

Insert a flathead screwdriver or 
similar tool into the groove, and 
remove the lower case. (Fig. 1)

2.

Fix the lower case with M4 x 25 
mm screws provided. Do not 
overly tighten, and use the 
provided spacers. If the Signal 
receiving unit does not fit in the 
wall, cut spacers to adjust the 
clearance.

3.

Connect the Signal receiving unit wiring (2-core control wire) with the wires 
extended from the indoor unit. (Fig. 2)
(Refer to the Wiring of the Signal Receiving Unit.) 
Be sure to determine the correct terminal numbers on the indoor unit when wiring 
the Signal receiving unit. The Signal receiving unit will be damaged if high voltage 
(such as 220 - 240 V) is applied.

4.

Reattach the upper case.

Wiring

<Wiring diagram>

<Wire joint>

1.

Strip the insulation to approximately 14 mm from the ends of the wires to be 
connected.

2.

Twist together the 2 wires and create a crimp connection at the wire joint.

3.

If a special crimping tool is not used, or if the connection is soldered, insulate the 
wires using insulation tape.

Mounting on the ceiling

1.

Cut a section out of the ceiling along the provided 
paper pattern (95 x 51 mm).

2.

Pass the wire through the provided mounting bracket 
and insert the bracket into the installation hole. (Fig. 3)

3.

Use bracket parts (A) and (B) to securely grip the 
ceiling material. (Fig. 4)

4.

Connect the Signal receiving unit control wire (2-core) 
to the control wire from the indoor unit. (Refer to 
“Wiring of the Signal Receiving Unit”.) Check the 
terminal number on the indoor unit before wiring the 
Signal receiving unit and be sure to wire correctly. 
(The unit will be damaged if high voltage, such as 220 
- 240 V, is applied.)

5.

Insert a slotted screwdriver into the opening at the 
bottom of the remote controller. Remove the lower 
case from the signal receiving unit.

6.

Adjust the provided spacers so that they are several 
millimeters larger than the thickness of the ceiling 
material. Pass the 2 supplied screws (M4 x 40 mm) 
through the spacers and tighten them enough to hold 
the Signal receiving unit in place.

7.

Return parts (A) and (B) through the gap between the 
ceiling and Signal receiving unit so that they are 
contained in the openings. Then tighten the screws.
Do not tighten the screws excessively. This may result 
in damage or deformation of the case.
Tighten to the point where the Signal receiving unit 
can be moved slightly by hand. (Fig. 5)

8.

Firmly attach the signal receiving unit to the lower 
case.

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)

Group control

Header and follower remote controllers are operable even if they are installed to any 
indoor unit. 
(Total wire length: Within 200 m)

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 3 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.

How to handle the remote controller

In case using remote controller mounting to the wall, etc.

Check a signal is received correctly by pushing 

 button at the position to be fixed.

Self-diagnosis function and measures

• The following table shows a few examples. For details of indoor unit errors, refer to 

the Installation Manual of the indoor unit.

Explanation to the customer

• After the installation work has been completed, execute a test run to check for normal 

operation and then hand the customer the Owner’s Manual and Installation Manual of 
the wireless remote controller kit.

• Explain how to use and maintain the wireless remote controller kit to the customer 

according to the Owner’s Manual of the wireless remote controller kit.

• Loading  Batteries

1.

Remove the battery cover.

2.

Insert 2 new batteries (R03 [AAA]) following the (+) 
and (-) positions.

Possible cause

Measures

These LEDs do not light or blink 
even if the remote controller is 
operated.

- Power is not turned on.
- Incorrect connection between 

signal receiving unit and 
indoor unit

Check connections and 
reconnect wires correctly, if 
necessary.

Loose connection between 
signal receiving unit and indoor 
unit

Incorrect or loose connection 
between indoor unit and 
outdoor unit

The protective device of the 
outdoor unit is activated.

Check the outdoor unit.

The protective device of the 
indoor unit is activated.

Check the indoor unit.
