含义
EEPROM数据异常。空调可开机运行但用户设置（定时、摆风、温度补偿等）在断电后丢失，或空调运行参数与设定不符。
常见原因
- EEPROM芯片数据校验错误或数据损坏
- 多次频繁断电导致EEPROM写入不完整
- EEPROM芯片与主控之间I²C通信干扰
- EEPROM供电3.3V不稳定
- 主板上EEPROM周边滤波电容漏电
自助排查
- 断电后等待1分钟重新上电，尝试恢复默认参数
- 进入设置菜单恢复出厂设置后重新配置
- 检查空调供电是否稳定，避免频繁插拔电源
- 如反复出现，可能需要更换主控板
English
Meaning
EEPROM data corruption. The AC operates but user settings (timer, swing, temperature offset) are lost after power cycling, or operating parameters do not match what was configured.
Common Causes
- Checksum error or corrupted data in the EEPROM
- Incomplete EEPROM write cycle due to frequent power cuts
- I²C communication interference between EEPROM and main MCU
- Unstable 3.3V supply to the EEPROM chip
- Leaking filter capacitor on the EEPROM supply line on the main board
Self-Check Steps
- Power off for 1 minute then restart to attempt default parameter recovery
- Perform a factory reset in the settings menu and reconfigure
- Ensure the AC has a stable power supply; avoid frequent plug/unplug cycles
- If the issue persists, main control board replacement may be needed
