<Overview of test run operations using the wireless remote controller>
Cooling test run:
ON/OFF → 18 °C → 17 °C → 18 °C → 17 °C → 18 °C → 17 °C → 18 °C → (test run) → ON/OFF
Heating test run:
ON/OFF → 29 °C → 30 °C → 29 °C → 30 °C → 29 °C → 30 °C → 29 °C → (test run) → ON/OFF
NOTE :
To prevent a continuous test run operation, 60 minutes timer release function is provided to this remote controller.
9-1-2. Forced Defrost Setup of Remote Controller (For wired remote controller only)
(Preparation in advance)
• Set the following CODE No. (DN) with the wired remote controller.
CODE No.(DN) : 8C
Set data : 0000 (Factory default) → 0001
(Practical operation)
• Push ON/OFF button.
• Select the HEAT mode.
• After a while, the forced defrost signal is sent to the outdoor unit and then the outdoor unit starts defrost operation.
(The forced defrost operation is performed for Max. 12 minutes.)
• After defrost operation finished, the operation returns to the heating operation.
To execute the defrost operation again, start procedure from above DN setting.
(If the forced defrost operation was executed once, setting of the above forced defrost operation is cleared.)

1. D501 (Red)
• It goes on (Goes on by operation of the main microcomputer) at the same time when the power supply is
turned on.
• It flashes with 1-second interval (every 0.5 second): When there is no EEPROM or writing-in operation fails.
• It flashes with 10-seconds interval (every 5 second): During DISP mode
• It flashes with 2-seconds interval (every 1 second): While setting of function select (EEPROM)
2. D403 (Red)
• It goes on when power supply of the remote controller is turned on. (Lights on hardware)
3. D503 (Yellow): Main bus communication
• For the indoor unit connecting to the central control device, D503 alternates between flashing for 5 seconds
and lighting for 5 seconds when the PC board receives the communication signal.
• For the indoor unit disconnecting to the central control device, D503 flashes every 5 seconds when the air
conditioner continues to stop the operation.
4. D504 (Green): Sub bus communication
• It flashes for 5 seconds in the first half of communication with the remote controller. (Group header unit)
• It flashes with 0.2-second interval (for 0.1 second) for 5 second in the latter half of communication between
header and follower in the Gr indoor unit.
5. D14 (Orange)
• It flashes while receiving the serial signal from the outdoor unit. (Hardware)
6. D15 (Green)
