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.
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. The 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.
