10 TROUBLESHOOTING 1.TROUBLES 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. (1) 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. C 100 (Short 238 bits) 80 60 Temperature 40 20 0 -20 -40 (Open 8 bits) 0 50 100 150 200 255 Number of bits 3-2 Fan output step To obtain data on the fan output step, add the number of bits of lighting LEDs, and see the graph below to find the fan rotational frequency.
