12 Remote controller check
When the remote controller does not work properly, use the remote controller checking function to
troubleshoot the problem.
(1) Check the remote controller display and see if anything is displayed (including lines). Nothing will
appear on the remote controller display if the correct voltage (8.5-12 VDC) is not supplied to the
remote controller. If this is the case, check the remote controller wiring and indoor units.
[Button operation]
1 Select "Remote controller check" from the Diagnosis menu, and press the SELECT button to start
the remote controller check and see the check results. To cancel the remote controller check and
exit the Remote controller check menu screen, press the MENU or the RETURN button. The
remote controller will not reboot itself.
OK: No problems are found with the remote controller. Check other parts for problems.
E3, 6832: There is noise on the transmission line, or the indoor unit or another remote controller is faulty. Check
the transmission line and the other remote controllers.
NG (ALL0, ALL1): Send-receive circuit fault. Remote controller needs replacing.
ERC: The number of data errors is the discrepancy between the number of bits in the data transmitted from the
remote controller and that of the data that was actually transmitted over the transmission line. If data errors
are found, check the transmission line for external noise interference.
2 If the SELECT button is pressed after the remote controller check results are displayed, remote
controller check will end, and the remote controller will automatically reboot itself.
