Troubleshooting
The following error indications appear on the fan coil unit display when a problem occurs.
Error detection and restart
• If an error occurs during operation, the display blinks to indicate an error and all operations except for the display
operation stop.
• When you restart the product using the remote control and the switch, a normal operation starts, and then the
detected error mode is determined.

NOTE
• If you stop the operation while an error is being indicated. all the indicators are turned off.
• In case of re-operation, a normal operation starts, and then the product reevaluate the detected error and displays it
again if required.
• If the E108 error occurs, set the FCU address again, and then reset the system.
Example) If the fan coil units 1 and 2 are set to the address 5, the fan coil unit 1 is changed from 1 to 5, and E108 and
A002 are displayed on the fan coil unit 2.
