12TROUBLESHOOTING

You can perform fault diagnosis of the outdoor unit with the LEDs on the P.C. board of the outdoor unit in addition to using the check codes displayed on the wired remote controller of the indoor unit.

Use the LEDs and error codes for various checks. Details of the error codes displayed on the wired remote controller of the indoor unit are described in the Installation Manual of the indoor unit.

Verifying Error code status (Outdoor control board)

1.Check that DIP switch SW803 is set to off.

2.Record the states (on or off) of LED 800 to LED 804 (Display mode 1).

3.Press SW800 for at least 1 second. The LED status changes to display mode 2.

4.Since display mode 1 covers multiple errors with the same code display, mode 2 must also be used to determine the final error. Use the status recorded for LED 800 to LED 804 in display mode 1 (Item 2 above) and combine it with the status for the same LED’s in display mode 2 (Item 3 above) to determine the complete error code using the chart below.

Verifying Error code status stored in memory (Outdoor control board)

1.Check that DIP switch SW803 is set to on.

2.Record the states (on or off) of LED 800 to LED 804 (Display mode 1).

3.Press SW800 for at least 1 second. The LED status changes to display mode 2.

4.Since display mode 1 covers multiple errors with the same code display, mode 2 must also be used to determine the final error. Use the status recorded for LED 800 to LED 804 in display mode 1 (Item 2 above) and combine it with the status for the same LED’s in display mode 2 (Item 3 above) to determine the complete error code using the chart below.

NOTE

An outside air temperature (TO) sensor error can be checked only when an error occurs.
