■ Controller check
When the controller does not work properly, use the remote controller checking func-
tion to troubleshoot the problem.
(1) Check the controller display and see if anything is displayed (including lines).
Nothing will appear on the controller display if the correct voltage (8.5-12 VDC)
is not supplied to the controller. If this is the case, check the controller wiring and
indoor units.
[Button operation]
1 Select "Remote controller check" from the Diagnosis menu, and press the SELECT
button to start the 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 controller will not reboot itself.
OK: No problems are found with the 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 control-
lers.
NG (ALL0, ALL1): Send-receive circuit fault. Controller needs replacing.
ERC: The number of data errors is the discrepancy between the number of bits in the
data transmitted from the controller and that of the data that was actually transmit-
ted 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 controller will automatically
reboot itself.
