INSTALLATION MANUALTo Personnel Charged in Installation Work and ServiceWireless remote controller kitModel: RBC-AX32U(W)-E, RBC-AX32U(WS)-EEB01600301 (EN)• Thank you for purchasing Wireless remote controller kit for TOSHIBA air conditioners.• Read this manual carefully for correct installation of the wireless remote controller kitbefore starting work.• After the installation is completed, execute a test run to check for normal operationand explain how to use and maintain the wireless remote controller kit to the customeraccording 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 wirelessremote controller kit, Installation Manual and Owner’s Manual of the 4-way cassettetype air conditioner (indoor unit), or the installation manual supplied with the ceilingpanel.AccessoriesSettings for the signal receiving unit before installationBefore installing the signal receiving unit, make the following settings referring to eachdescription.• 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 unitInstall the signal receiving unitin correct orientation, sincethe signal receiving unit canbe installed at only one corneras shown in (Fig. 1).1. Remove the air intake grille.2. Remove the adjust cornercap at the corner where thesignal receiving unit is to beinstalled. (Fig. 2)Pull the knob of the adjust corner cap in the arrow 1 direction. Remove the adjustcorner cap.* The knob is provided only on one side of the cap. Be sure to detach the cap from theknob side.3. A pad is packed in the two rectangular holes (indoor unit side and signal receivingunit side) for ceiling panel wires. Remove the pads temporarily, and pass the wiresfrom 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” belowwithout slack of the wires, pull the black pad that covers the wire by approx. 20 mmout of the rectangular hole on the indoor unit side, and then clamp the wires with thesupplied clamp tightened with the screw. Then return the packing removed from therectangular 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 waterleakage or dew drop on the unit and wires.Part Name Q’tySignal receiving unit1Remote controller 1Remote controller holder 1Battery 2Owner’s Manual 1Installation Manual (thismanual) 1Tapping screwM4 × 16 mm 2Clamp 1Clamp screwM4 × 12 mm 1Part Name Q’tyIndoor unitdrain pipe sideIndoor unitrefrigerant pipesideIndoor unitelectricalcontrol boxSignal receivingunit installingposition(Fig. 1)1Adjust corner capKnob Ceiling panelAdjust corner cap(Fig. 2)Clamp Remove the pad from therectangular hole on the signalreceiving unit side, clamp thewires with the clamp, secure theclamp with the M4 x 12 mmscrew, and then return the pad tothe original position.Pull the black pad that covers the wireby approx. 20 mm out of the hole.Remove the pad from therectangular hole on the indoorunit side.(Fig. 3)5. Attach the signal receiving unit to the ceiling panel, while taking care not to catch thewires. (Fig. 4)• Push the three claws of the adjust corner cap firmly as far as they will go. Failure todo so may result in water leakage.Note: Do not bundle these control signal wires with the power wire to avoidmalfunction.How to wire the signal receiving unitConnect the wires from the signal receiving unit to the remote controller connectionterminal 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 installationThe control by two remote controllers is enabled by installing the wireless remotecontroller 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 themultiple remote controllers.Note:1. Upon confirmation of the terminal numbers of the indoor unit, connect the controlwire without miswiring. (If applied 220 - 240 V, damage the unit.)2. The multiple wireless remote controller kits cannot concurrently be used for anindoor unit.3. When installing simultaneously the wireless remote controller with the wired remotecontroller, 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 eachcontroller.• To use the wireless remote controller as a follower, set bit 4 (Follower side) of DIPswitch SW30 on the signal receiving unit P.C. board to ON.2-remote controllersThe indoor unit is operated if either wireless or wired remote controller is set as headeror follower remote controller.(Total wire length: Within 400 m)Rectangular holesClawsInsert the two claws on the adjust cornercap (with signal receiving unit) into therectangular holes of the ceiling panel inthe arrow direction.Push the adjust corner cap in the arrowdirections so that the three claws arefitted.(Fig. 4)Indoor unit Signal receiving unitWhiteBlack whiteRemote controllerconnectionterminal blockElectrical control boxIndoor unit remotecontroller connectionterminal blockClamps Clamping clawSignal receiving unitA BWireless remotecontroller kit (Header)Wired remotecontroller (Follower)(Sold separately)Control wire(Locally procured)2 x 0.5 to 2.0 mm2Indoor unitEarthRemote controllerconnection terminalblockSignal receiving unitGroup controlHeader and follower remote controllers are operable even if they are installed to anyindoor 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 addresscan be set for each signal receiving unit to prevent interference.• Address (A-B selection) must be changed on both signal receiving unit and wirelessremote controller.• For the details of address change (A-B selection) on wireless remote controller, referto the owner's manual.Turn off the indoor unit power supply. Turn on the bit 4 of DIP switch SW30 on thesignal receiving unit P.C. board.The setting change is shown below.DIP switch [SW30]Test run (Forced cooling operation)Requirement:• Finish the forced cooling operation in a short time because it applies excessivestrength to the air conditioner.How to perform forced cooling operation1. When TEMPORARY button is pushed for 10 seconds or more, “Pi!” sound is heardand the operation changes to a forced cooling operation. After approx. 3 minutes, acooling 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.4 ON=follower OFF=header3 ON=B OFF=A2 Not used1 Not usedA B A B A B A BWireless remotecontroller kit (Header)Wired remotecontroller (Follower)(Soldseparately)Control wire for group control(Locally procured)2 x 0.5 to 2.0 mm 2EarthRemotecontrollerconnectionterminal blockSignal receivingunitEarth Earth EarthIndoor unitNo.1Indoor unitNo.2Indoor unitNo.3Indoor unitNo.4Clamper ScrewDIP switch SW30Signal receiving unit P.C. boardAdjust corner cap with signal receiving unitSignal receiving unit coverSW301ON2 3 434TEMPORARYbuttonHow to handle the remote controller• To set the remote controller on the wallPush button at the installation position on the wall to check that the signal from theremote controller is received correctly.• Loading Batteries1.
