IGBT built-in sensor error in A3-IPDU
This error code means IGBT built-in temperature sensor error.
Check connection of connectors CN06 on IPDU P.C. board and CN600 on I/F P.C. board.
If sensor is normal, replace IPDU P.C. board.
This error code means detection of Open/Short of TL sensor. Check disconnection of circuit for connection of
connector (TL sensor: CN523, White) and characteristics of sensor resistance value. (See "Outdoor unit temperature
sensor characteristics" on "9-9. Sensor Characteristics".)
If sensor is normal, replace outdoor I/F P.C. board.
This error code means detection of Open/Short of TO sensor. Check disconnection of circuit for connection of
connector (TO sensor: CN507, Yellow) and characteristics of sensor resistance value. (See "Outdoor unit temperature
sensor characteristics" on "9-9. Sensor Characteristics".)
If sensor is normal, replace outdoor I/F P.C. board.
This error code means detection of Open/Short of TA sensor. Check disconnection of circuit for connection of
connector (TA sensor: CN104, Yellow) and characteristics of sensor resistance value. (See "Indoor unit temperature
sensor characteristics" on "9-9. Sensor Characteristics".)
If sensor is normal, replace indoor P.C. board.
This error code means detection of Open/Short of TS1 sensor. Check disconnection of circuit for connection of
connector (TS1 sensor: CN505, White) and characteristics of sensor resistance value. (See "Outdoor unit temperature
sensor characteristics" on "9-9. Sensor Characteristics".)
If sensor is normal, replace outdoor I/F P.C. board.
Open/short of TF / TFA sensor was detected. Check disconnection of connector connection (TFA sensor: CN103
yellowish green) circuit and resistance value characteristics of the sensor. (Refer to "9-9 Sensor Characteristics
Indoor Unit Temperature Sensor Characteristics".) When the sensor is normal, replace the indoor P.C. board.
