10 TROUBLESHOOTING 1.TROUBLE IN TEST RUN Symptom Cause Check points The display “CENTRALLY CONTROLLED” on remote controller dose not disappear. 1) Wrong address setting of remote controller/indoor controller board. 2) Timer adapter is connected to the remote controller. 3) Singnal transmission error between indoor unit and remote controller. 1) Check the address setting of remote controller and indoor controller. 2) Make sure the timer adapter is used correctly.
2. SELF DIAGNOSTIC FUNCTION WITH REMOTE CONTROLLER 2-1 When malfunction occurs during operation When a malfunction occurs, the indoor and outdoor units stop and the malfunction is displayed on the LCD of the remote controller. (A) ON the set temperature display part, “CHECK” appears, and the unit address and the check code are diplayed alternately at one-second intervals.
Check Diagnosis of malfunction Cause Check points code EO Signal transmitting/receiving During individual unit control 1) Check the transmission wire. error 1) Bad contact of transmission 2) Check with another remote controller. If “EO” is (Indoor controller does not wire still indicated, replace the indoor controller respond to remote controller 2) Signal transmitting/receiving cirboard. signal.) cuit is abnormal. If other check code appears. replace the original remote controller.
3.SERVICE DATA INDICATION BY SWITCHES ON OUTDOOR CONTROLLER BOARD Setting dip switchs SW2 and SW3 on the outdoor controller board enables LED to show the output state and check code. Output state is shown by LED lighting, and check code by blinking. SW1 : Turning SW1 ON clears the check code. If SW1 is turned ON while the check code is blinking , the indication changes to output state indication. NOTE : SW1 is usually available independant of SW3 setting.
3-1 Outdoor coil temperature To obtain data on the outdoor coil temperature, add the number of bits of lighting LEDs, and see the graph below to find the temperature.

6. WRONG WIRING ON SITE 6-1 Between remote controller and indoor unit If the wire is disconnected between the remote controller and the indoor unit, nothing is displayed on the remote controller when the POWER button is pressed. The beep sound will also not be heard.
7. OTHER TROUBLES AND CAUSES Vanes do not work. Unit stops after 5 to 20 seconds operation Air discharge display is OFF and button does not operate. In this case, remote controller is normal. Power ON/OFF button is not available. Vane motor does not work. Limit swtich does not work. Connector is poorly connected. Vane motor is poorly assembled. Indoor controller board is damaged. Beep sound is heard, but display is turned OFF. Beep sound is not heard, and display remains OFF. Limit switch is damaged.
11 4-WAY AIR FLOW SYSTEM 1.Placement of the air outlets ●For this grill, the air flow direction comes in 5 patterns. Also, by setting the dipswitches (SWA and SWB)on the indoor board to the appropriate settings, you can adjust the air flow and speed. Select the settings that are needed from those in Tables 2 and 3 according to the place where you want to install the unit. 1) Decide on the pattern of the airflow direction.
12 SYSTEM CONTROL 1. VARIETY OF SYSTEM CONTROL FUNCTIONS 1 Group control with a single remote controller (See page 53.) Unit Unit Unit Remote controller 2 Both remote ON/OFF and individual controls (See page 54.) w Timer adapter (PAC-SA89TA-E) is needed. Optional adapter Relay box Unit Remote ON/OFF switch 3 Individual control by grouping remote controllers (See page 55.) Remote controller Unit Unit Unit Remote controller 4 Multiple remote control display (See page 55.
2. GROUP CONTROL WITH A SINGLE REMOTE CONTROLLER A maximum of 50 units can be started in order according to the dip switch settings 2-1 How to wire (1) Connect the remote controller to the double terminal block on the indoor controller board of the master unit (No.0 unit). (See Figure 1.) (2) Connect the double terminal block of the master unit to the double terminal block of No.1 unit. (3) Connect the double terminal block of No.1 unit to the double terminal block of No.2 unit.
3. REMOTE ON-OFF AND INDIVIDUAL REMOTE CONTROLS This method is available to control one unit or any number of units. The following operations are available by connecting a relay, a timer adapter (PAC-SA89TA-E), and a remote ON/OFF switch to the system. Timer adapter is an optional part. Other parts are available on the market.
4. INDIVIDUAL CONTROL BY GROUPING THE REMOTE CONTROLLERS ● Grouping the remote controllers allows individual control and centralized monitoring of units installed in different places without a special control board. ● Remote control cables are extendable up to 500m. When the cable length exceeds 12m, use the double-insulated two-care cable such as Belden 9407. Also, the cable thickness must be No. 22 AWG or above.
6. AUTO RESTART FUNCTION By setting the dipswitch SW1-10 to ON, the air conditioner can be started/stopped by power supply ON/OFF. If the air conditioner is OFF before the power failure, it will not start operation by power restore.
