[. . . ] Defect Replace ­ 80 ­ [E03 error] (Master indoor unit) [E03 error] is detected when the indoor unit cannot receive a signal from the remote controller (also central controller). Check A and B remote controllers and communication lines of the central control system U3 and U4. As communication is impossible, this check code [E03] is not displayed on the remote controller and the central controller. [E01] is displayed on the remote controller and [C06 error] is displayed on the central controller. If these check codes generate during operation, the air conditioner stops. [F29 error] This check code indicates a detection error of IC10 non-volatile memory (EEPROM) on the indoor unit P . C. board, which generated during operation of the air conditioner. When EEPROM was not inserted when power supply turned on or when the EEPROM data read/write operation is impossible at all, the automatic address mode is repeated. In this time, [97 error] is displayed on the central controller. (Approx. 1 minute) [SET] goes off. [SET] is displayed on remote controller. LED (D02) on indoor unit P. C. 10 seconds. Reboot (Reset) (Repetition) [P31 error] (Follower indoor unit) When the master unit of a group operation detected [E03], [L03], [L07] or [L08] error, the follower unit of the group operation detects [P31 error] and then the unit stops. There is no display of the check code or alarm history of the remote controller. c) Are connecting cables of indoor unit and remote controller correct? 2. Troubleshooting procedure When a trouble occurred, check the parts along with the following procedure. Trouble Confirmation of check code display Check defective position and parts. NOTE : For cause of a trouble, power conditions or malfunction/erroneous diagnosis of microcomputer due to outer noise is considered except the items to be checked. If there is any noise source, change the cables of the remote controller to shield cables. ­ 83 ­ <Wireless remote controller type> 1. Before troubleshooting 1) Required tools/instruments · + and ­ screwdrivers, spanners, radio cutting pliers, nippers, etc. · Tester, thermometer, pressure gauge, etc. 2) Confirmation points before check a) The following operations are normal. · Is not 3-minutes delay (3 minutes after compressor OFF)?· Is not the outdoor unit in standby status though the remote controller reached the setup temperature?· Does not timer operate during fan operation?· Is not an overflow error detected on the indoor unit?· Is not outside high-temperature operation controlled in heating operation?
