ERROR

CODE

Communication
error

1. When power turned off, then turned on
again:
1) If error not generated again, PC board
is normal. Therefore, remove noise
sources near outdoor unit.
2) If error generated again, perform
following, in addition to removing noise
sources.

1. Affect of extraneous noise.

1. Generation condition.
Communication from indoor
units cuts off certain time.
2. Corresponding operation.
1) When communication error
generated 90 seconds after
outdoor unit circuit board
error 1 generated, all
compressors stopped.
2) When communication from
all indoor units cuts off
certain time, all compressors
stopped and error display
to outdoor unit LED.
3) For other than the above,
only indoor units that
completed communications
are operation target. Error
display to outdoor unit LED.
3. Reset condition.
Communication with indoor
units restored.

1F

2. Check if communication line connected
to all indoor units.

3. Check indoor units power supply.

4. Check insertion of indoor unit
communication PC board and outdoor
unit communication PC board.

5. 1) If communication error generated
after outdoor unit circuit board error
generated, replace PC boards in
following order and check operation.
(1) Outdoor unit communication PC board.
(2) Outdoor unit control PC board.
2) If some indoor units in same refrigerant
operated, replace PC boards in
following order and check operation:
(1) Communication PC board of indoor
unit that generated communication
error.
(2) Control PC board of indoor unit that
generated communication error.
3) When all indoor units in same
refrigerant system generate an error
and compressor does not operate,
replace PC boards in following order
and check operation.
(1) Outdoor unit communication PC board.
(2) Outdoor unit control PC board.
(3) Indoor unit communication PC board.
(4) Indoor unit control PC board.

2. Communication line not
connected, contact faulty, or
line open.

3. Indoor unit power OFF.

4. Indoor unit communication PC
board or outdoor unit
communication PC board
insertion faulty.

5. PC board faulty.
