1. D501 (Red)
• D501 goes on at the same time when the power supply is turned on.
(Goes on with operation of the main microprocessor)
• D501 flashes with 1-second interval (every 0.5 second) : When there is no EEPROM or write-in error
• D501 flashes with 10-seconds interval (every 5 second) : In DISP mode
• D501 flashes with 2-seconds interval (every 1 second)
: During setting of function exchange (EEPROM)
2. D403 (Red)
• D403 goes on when power is supplied to the remote controller. (ON in hardware)
3. D503 (Yellow): Indoor/Outdoor central control
• D503 goes on for 5 seconds at the first half during communication with the central controller.
• D503 flashes for 5 seconds with 0.2-second interval at the latter half during communication with outdoor unit.
(Goes on for 0.1 second, goes off for 0.1 second)
4. D504 (Green): Remote controller communication
• D504 goes on for 5 seconds at the first half during communication with remote controller.
(Header unit of group)
• In the group indoor unit, D504 flashes for 5 seconds with 0.2-second interval at the latter half during
communication between header and follower unit. (Goes on for 0.1 second, goes off for 0.1 second)
5. D14 (Orange)
• It flashes while receiving the serial signal from the outdoor unit. (Hardware)
6. D15 (Green)
• It flashes while sending the serial signal to the outdoor unit. (Hardware)
