(1) Contact is faulty.
(2) INV board fault.
(3) DCCT sensor is faulty.
(4) Compressor ground fault and
IPM fault.
(1) ACCT sensor is dislocated
(2) Wire connection is faulty.
(3) ACCT is faulty.
(4) Compressor is disconnected
(5) Inverter circuit is faulty.
(1) ACCT sensor incorrectly
installed.
Check the contacts around the
INV board connector CNCT and
DCCT side connector.
Refer to
9
.[4].7.(2).[1]
“Check the INV board error
detection circuit”.
If there is no problem up to step
(2), replace
DCCT and check the DCCT
polarity.
Refer to
9
.[4].7.(2).[2]
“Check for com-pressor ground
fault or coil error.”
Refer to
9
.[4].7.(2).[5]
“Check the inverter circuit trouble”.
Check CNCT2 sensor
connection (Check ACCT
installation state)
Check CNDR2 connection on
INV board, or CNDR1
connection on G/A board
Refer to

trouble”.
Refer to

“Current sensor ACCT”.
An abnormal value was
detected with the DCCT
detection circuit just before the
INV started.
IPM open damage or CNCT2
dislocation was detected just
before INV started. (Sufficient
current was not detected during
self-diagnosis just before
starting.)
Improper installation of the
ACCT sensor was detected.

6600 (1) Two or more controllers of
outdoor unit, indoor unit,
remote controller, etc. have
the same address.
<Example>
Error display of the remote
controller 6600 “01”
Unit No.1 detected the error
Two Units No.1 or more are in
a same system.
Search for the unit which has the same
address with that of the source of the
trouble.
When the same address is found,
turn off the power source of
outdoor unit, and indoor unit for 5
minutes or more after modifying
the address, and then turn on it
again.
Multiple address abnormality
Transmission from units with the
same address is detected.
Note:
The address/attribute shown on
remote controller indicates the
controller which has detected
error.

(1) No voltage is applied to the
M-NET transmission line that
G-50A is connected to.
(2) M-NET transmission line to
which G-50A is connected is
short-circuited.
Check if power is supplied to the M-
NET transmission line of the G-50A,
and correct any problem found. Unset polarity
The error detected when
transmission processor cannot
distinguish the polarities of the
M-NET transmission line.
