This error code means detection of Open/Short of TD1 sensor. Check disconnection of circuit for connection of
connector (TD1 sensor: CN502, 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 TD2 sensor. Check disconnection of circuit for connection of
connector (TD2 sensor: CN503, Pink) 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 TE1 sensor. Check disconnection of circuit for connection of
connector (TE1 sensor: CN520, Green, TE2 sensor: CN521,Red ) and characteristics of sensor resistance value.
(See gOutdoor unit temperature sensor characteristics h on "9-9. Sensor Characteristics".)
If sensor is normal, replace outdoor I/F P.C. board.
