Alarm contents
Faulty remote controller
Disconnection / Contact failure of remote
controller wiring
CHK (check) pins on the indoor unit control
PCB are short circuited
In the case of non-group control
 Power supply OFF of outdoor unit
 Disconnection / Contact failure of inter-unit
wiring
In the case of group control
Automatic address operation was not carried
out
Faulty setting of EEPROM (IC010) on indoor
unit
Faulty remote controller
Wrong wiring of remote controller
Error in indoor unit receiving signal from remote
controller (central)
Disconnection / Contact failure of inter-unit
wiring
 Faulty indoor unit control PCB
 Faulty outdoor unit control PCB
 Communication circuit fuse (F302) on indoor
unit control PCB opened
 Fuse on outdoor unit control PCB opened
Since failure of an outdoor fan motor is
considered as a cause, both outdoor unit
control PCB and outdoor unit fan motor are
exchanged simultaneously
Duplication of indoor unit address setting
Error because of more than one remote
controller setting to main
 Disconnection of wiring between main unit
and additional units
 Contact failure of wiring
 Faulty indoor unit control PCB (main or
addition)
Indoor heat exchanger temperature sensor
(E1) trouble
Indoor heat exchanger temperature sensor
(E2) trouble
Indoor air temperature sensor (TA) trouble

Error location
 Replace the remote controller
 Correct the remote controller wiring
 Remove the short
 Execute auto address setting
 Replace the indoor unit EEPROM
 Replace the remote controller
 Correct the remote controller wiring
 Check the indoor unit control PCB
 Check the remote controller wiring
 Check the inter-unit control wiring
 Check the electrical connection of inter-unit
control wiring
 Replace the indoor unit control PCB
 Replace the outdoor unit control PCB
 Check the electrical connection of fuse
(F302) on indoor unit control PCB
In the case of the fuse opened on an indoor
unit control PCB, after correcting wiring
connection, it substitutes an EMG plug for
OC plug
 In the case of the fuse opened on an outdoor
unit control PCB, replace both outdoor unit
control PCB (CR/HIC) and outdoor unit fan
motor simultaneously
 Indoor unit address re-setting
 Correct the setting
 Correct the wiring connection
 Replace the wiring
 Replace the indoor unit control PCB
 Check the indoor unit heat exchanger
temperature sensor (E1)
 Check the indoor unit control PCB
 Check the indoor unit heat exchanger
temperature sensor (E2)
 Check the indoor unit control PCB
 Check the indoor unit air temperature sensor
(TA)
 Check the indoor unit control PCB
