2. Once, press the button, and the display change

“ ”.

3. Press the (SET) button and abnormal operation data mode is started.
4. When only one indoor unit is connected to remote control, following is displayed.

①

The case that there is history of abnormal operation.

Error code and “ ” is displayed.

[Example]: [E8] (ERROR CODE)
“ ” is displayed (blinking indication during data loading).
Next, the abnormal operation data of the indoor unit will be displayed. Skip to step 8.

②

The case that there is not history of abnormal operation.

“ ” is displayed for 3 seconds and this mode is closed.

5. When plural indoor units is connected, following is displayed.

①

The case that there is history of abnormal operation.

Error code and the smallest address number of indoor unit among all connected indoor
unit is displayed.

[Example]: [E8] (ERROR CODE)
“ ” blinking

②

The case that there is not history of abnormal operation.

Only address number is displayed.

6. Select the indoor unit number you would like to have data displayed with the

button.

7. Determine the indoor unit number with the (SET) button.

[Example]: [E8] (ERROR CODE)
“ ” (The address of selected indoor unit is blinking for 2 seconds.)

[E8] “ ” (A blinking indication appears while data loaded.)
Next, the abnormal operation data is indicated.
If the indoor unit doing normal operation is selected, “ ” is displayed for 3
seconds and address of indoor unit is displayed.

8. By the button, the abnormal operation data is displayed.

③

Trial operation

※

Depending on models, the items that do not have corresponding data are not displayed.

9. To display the data of a different indoor unit, press the AIR CON No. button, which allows

you to go back to the indoor unit slection screen.

10.Pressing the button will stop displaying data.

Pressing the (RESET) button during remote control unit operation will undo your last

operation and allow you to go back to the previous screen.

◎

If two ( 2) remote control are connected to one (1) indoor unit, only the master control is

available for trial operation and confirmation of operation data. (The slave remote control is
not available.)

The operation data is saved when the situation of abnormal operation happen, and the data
can be confirmed by remote control.
