Settings for the signal receiving part before installation

Before installing the signal receiving part, make the following settings referring to each description.

• When installing wireless remote controller together with wired remote controller → Perform “Settings when installing the wireless remote controller kit together with wired remote controller”

• When ceiling height exceeds the standard height (factory setting) → Perform “Settings for high ceiling”

• When installing multiple signal receiving parts in a room → Perform “Remote controller address setting”

How to attach the signal receiving part

Since the signal receiving part can be attached at only one corner shown in (Fig. 1), be careful of the orientation of the signal receiving part after the ceiling panel is attached to the indoor unit.

1. Detach the air inlet grille.

2. Detach the adjust corner cap at

the corner where the signal receiving part is to be installed. (Fig. 2) Pull the knob of the adjust corner cap in the arrow 1 direction, and detach 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.

(Fig. 2)

3. A pad is packed in the two rectangular holes (indoor unit side and signal receiving part side) for

ceiling panel wires. Remove the pads temporarily, and pass the wires from the wireless signal receiving part through the rectangular holes. (Fig. 3)

4. After the wiring is completed following “How to wire the signal receiving part” 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 clamper tightened with the screw. Then return the packing removed from the rectangular hole on the signal receiving part 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

(Fig. 3)

Attach the signal receiving part 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.

* For details of the wiring and test run, refer to “How to wire the signal receiving part” and “Test run” below.

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

• 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.

How to wire the signal receiving part

Connect the wires from the signal receiving part to the remote controller connection terminal block of the indoor unit. (The terminals are nonpolar.)

• Clamp the redundant portion of the wires with the clampers in the electric parts box.

Test run

Perform usual operations using the remote controller to check for normal operation. A test run can be executed forcibly by using the following procedure if the room temperature is too high to turn off the thermostat.

1. Turn off the power of the air conditioner, and remove the screws to detach the signal receiving

part cover.

2. Set bit 1 of DIP switch S003 on the signal receiving part P.C. board to ON.

3. Attach the signal receiving part to the ceiling panel by reversing the procedure of removal, and

then turn on the power of the air conditioner.

4. Push [START/STOP] on the wireless remote controller, and select COOL or HEAT with [Mode

select]. (Temperature cannot be controlled during a test run.)

5. All LEDs on the signal receiving part flash during a test run.

6. After the test run has been completed, be sure to set bit 1 of DIP switch S003 to OFF and confirm

that the LEDs do not flash.

7. Clamp the wires properly with the clamper secured together with the signal receiving part cover.

Note 1: Use the forced test run only for test run because it overloads the air conditioner. Note 2: The remote controller is disabled for approx. 1 minute after power-on, but this is normal. The signal

from the remote controller is received, but the receive data is discarded.

Settings when installing the wireless remote controller kit together with wired remote controller

A dual remote controller system is available by installing the wireless remote controller kit together with the wired remote controller. (Up to two wireless and wired remote controllers can be installed.) The dual remote controller system controls one or more indoor units with two remote controllers.

Note: Connect wires correctly to the signal receiving part, checking terminal numbers on the indoor unit. If

220/240 VAC is applied, the circuit will be broken.

Note: Multiple wireless remote controller kits cannot be attached to one indoor unit. Note: To use the wireless remote controller kit together with the wired remote controller, set either

remote controller to a follower remote controller.

• To use the wired remote controller as a follower, change the setting of the DIP switch on the back of the wired remote controller P.C. board from Header to Follower. For changing DIP switch setting, refer to the installation manual of the wired remote controller.

• To use the wireless remote controller as a follower, set bit 3 of DIP switch S003 on the signal receiving part P.C. board to ON.

Controlling one indoor unit by two remote controllers

• The indoor unit is operable regardless of the settings (Header or Follower) of the remote controllers.

Settings for high ceiling

• When an indoor unit is installed on a ceiling higher than the standard height (factory setting shown in the table below) or when changing the number of air discharge ports by using the windshield kit (separately sold), the DC fan tap is required. Bit 2 (tap 1) and bit 4 (tap 2) of DIP switch S003 on the signal receiving part P.C. board are used for the DC fan tap setting. Change the setting with DIP switch S003 on the signal receiving part P.C. board of this product (RBC-AX31U). The setting change is shown below.

Remote controller address setting

• When two or more signal receiving parts are installed in a room, a unique address can be set for each signal receiving part to prevent interference.

• When you push the reset button after replacing batteries, the address displayed on the remote controller shows “ALL” While “ALL” is displayed, signals from the remote controller can be received regardless of the setting of the address switches in the signal receiving part.

• For how to change remote controller addresses, refer to the Owner’s Manual.

• Detach the signal receiving part cover of the signal receiving part when changing the signal receiving part address. After the setting change has been completed, clamp the wires properly with the clamper secured together with the signal receiving part cover.
