Explanation of error contents
Open/Short of discharge temp. sensor was detected.
Open/Short of heat exchanger temp. sensor was detected.
Miswiring between TE sensor and TS sensor
Open/Short of outside temp. sensor was detected.
Open/Short of heat exchanger temp. sensor was detected.
Open/Short of suction temp. sensor was detected.
Open/Short of heat sink temp. sensor (Board installed) was detected.
Misconnection of outdoor heat exchanger temp. sensor and suction temp. sensor was detected.
Outdoor P.C. board part (EEPROM) error was detected.
When reached min-Hz by current release control, short-circuited current (Idc) after
DC excitation was detected.
Compressor lock was detected.
Current detection circuit error
Case thermostat operation was detected.
When outdoor service P.C. board was used, model type select jumper setting was inappropriate.
1) Defective parts on outdoor P.C. board (MCU communication, EEPROM, TH sensor error)
2) When outdoor service P.C. board was used, model type selection was inappropriate.
3) Other error (Heat sink abnormal overheat, gas leak, 4-way valve inverse error) was detected.
Error was detected by discharge temp. release control.
When case thermostat worked, error was detected by high release control from indoor/
outdoor heat exchanger temp. sensor. Power supply voltage error
Power supply voltage error
Abnormal overheat was detected by outdoor heat sink temp. sensor.
Abnormal overheat of discharge temp. or suction temp. was detected.
Error was detected by high release control from indoor/outdoor heat exchanger temp. sensor.
Error (Over-current, lock, etc.) was detected on outdoor fan drive circuit.
Short-circuited protective operation of compressor drive circuit element (G-Tr /IGBT) worked.
Position detection error of compressor motor was detected.
Signal was not received from indoor unit.
Main remote controller was not set. (including 2 remote controllers)
Signal cannot be sent to indoor unit.
No communication from remote controller and network adapter
Serial communication error between indoor and outdoor
Same address as yours was detected.
In 2-remote controller control, both were set as master.
(Indoor master unit stops warning and follower unit continues operation.)
MCU communication error between main motor and micro computer
Regular communication was impossible between master and follower indoor units.
Communication between twin master (Main unit) and follower (sub unit) was impossible.
There are multiple master units in a group.
When even one group connection indoor unit exists in individual indoor unit
Indoor address group was unset.
Capacity of indoor unit was unset.
Abnormal stop by CN80 outside error input
In heating operation, error was detected by temp. down of indoor heat exchanger or temp. up ofTE, TS.
