1. Error Code
Transmission line bus busy error
2. Error definition and error detection method
Generated error when the command cannot be transmitted for 4-10 minutes in a row due to bus-busy
Generated error when the command cannot be transmitted to the transmission line for 4-10 minutes in a row due to noise
The address/attribute appeared on the display on the remote controller indicates the controller where an error oc-
curred.
3. Cause, check method and remedy
1. Error Code
Communication error between device and transmission processors
2. Error definition and error detection method
Communication error between the main microcomputer on the indoor unit board and the microcomputer for transmission
The address/attribute appeared on the display on the remote controller indicates the controller where an error oc-
curred.
3. Cause, check method and remedy
6603
Cause Check method and remedy
(1) The transmission processor cannot be transmit-
ted as the short-wavelength voltage like noise ex-
ists consecutively on the transmission line.
Check the transmission wave shape and noise on the
transmission line.
Refer to the service handbook that came with the outdoor
unit.
-> No noise indicates that the error source controller is a
failure.
-> If noise exists, investigate the noise.
(2) Error source controller failure
6606
Cause Check method and remedy
(1) Data is not properly transmitted due to accidental
erroneous operation of the controller of the error
source.
Turn off the power source of the outdoor and the indoor
units.(When the power source is turned off separately, the
microcomputer will not be reset, and the error will not be
corrected.)
-> If the same error occurs, the error source controller is
a failure.
(2) Error source controller failure
