Check of anomalous operation data with the remote control
(a) In case of RC-EX3 remote control
[Operating procedure]
➀ On the TOP screen, touch the buttons in the order of "Menu" ➝ "Service setting" ➝ "Service & Maintenance" ➝
"Service password" ➝ "Set" ➝ "Error display" ➝ "Error history".
➁ When only one indoor unit is connected to the remote control, followings will be displayed.
1. When there is any anomaly: "Loading. Wait a while" is displayed, followed by the operation data at the occurrence
of anomaly
Contents of display
・ Error code
・ Number and data item
2. When there is no anomaly: "No anomaly" is displayed, and this mode is terminated.
➂ When two or more indoor units are connected to the remote control, followings will be displayed.
1. When there is any anomaly: If the unit having anomaly is selected on the "Select IU" screen, "Loading. Wait a while"
is displayed, followed by the operation data at the occurrence of anomaly.
Contents of display
・ Indoor unit No.
・ Error code
・ Number and data item
2. When there is no anomaly: "No anomaly" is displayed, ant this mode is terminated.
Note (1) When the number of connected units cannot be shown in a page, select "Next".
➃ If you press [RUN/STOP] button, the display returns to the TOP screen.
◎ If you touch "Back" button on the way of setting, the display returns to the last precious screen.
Note (1) When two remote controls are used to control indoor units, the check of anomaly operation data can be made on the master remote control only. (It
cannot be operated from the slave remote control.)
■ Anomaly operation data (Corresponding data may not be provided depending on models. Such items will not be displayed.)
