Trouble diagnosis

<<Checks and inspections>>

• When trouble has occurred in the air conditioner, an

inspection code and the number of the indoor unit

concerned blink on the numeric display.

• Inspection codes are displayed only during operation.

• If the display has gone off, check the trouble by

following the steps in “Checking the trouble history”

below.

<<Checking the trouble history>>

• When trouble has occurred in the air conditioner, the

trouble history can be checked by following the steps

below. (Up to four events are stored in the trouble

history.)

• The trouble history can be checked whether the air

conditioner is running or shut down.

1 Push the button (42) and button (43)

together for at least 4 seconds.

• The numeric displays blink, and the servicing

display and inspect display light.

2 Push the TEMP or button (49).

• Each time one of these buttons is pushed, the

trouble history events are displayed in numerical

order.

• The “01” code on the numeric display indicates the

latest event, and “04” the earliest event.

* Do not push the button (41) since all the

trouble history events of the indoor units will be

deleted.

3 After checking the events, push the button

(43) to return to the original screen.

Concerning trouble occurring in the remote

controller

“ ”, “ ” and “ ” blink at the same time.

• This means that trouble has occurred on the remote

controller’s circuit board. Contact your dealer.

• Normal air conditioner operations are still possible, but

no scheduled operations can be performed.

<Caution> If the problem persists even after

checking out the above points, stop operating the air

conditioner, set the ground fault interrupter to off, and

give the model number and details of the symptoms to

your dealer. Do NOT attempt to remedy the

problem yourself due to the dangers involved.
