1.D501 (Red)
• Lights up when the power is turned on (Microcomputer works)
• Blinks at 1-second intervals (0.5-second): No EEPROM, or writing error
• Blinks at 10-second intervals (5-second): No DISP mode
• Blinks at 2-second intervals (1-second): Function change being set (EEPROM)
2.D403 (Red)
• Lights up (on hardware) when the power is supplied to the remote controller
3.D503 (Yellow): Indoor/Outdoor central control
• Lights up for the first half 5 seconds while communicating with a central control device
• Blinks for the second half 5 seconds at 0.2-second intervals (0.1-second) while communicating with
the outdoor unit
4.D504 (Green): Remote controller communication
• The group header unit lights up for the first half 5 seconds while communicating with the remote
controller
• Blinks for the second half 5 seconds at 0.2-second intervals (0.1-second) during communication
between group indoor header and follower
