Indoor ambient temp. sensor
failure
Indoor coil temp. sensor failure
Outdoor ambient temp. sensor
failure
Outdoor coil temp. sensor A
failure(compressor discharging
temp. sensor)
Over-current protection
High pressure abnormal
Power failure in overvoltage or
lackvoltage, phase error (fixed
frequency multi split)
Communication between wired
controller and indoor abnormal
Communication between indoor
and outdoor abnormal
Outside alarm signal input
Fault in discharging temp.
sensor A
EEPROM abnormal
Outdoor pressure switch or
discharging protector abnormal
Compressor overheat
Fault in operation mode (fixed
frequency multi split)
Outdoor coil temp. sensor B
failure

22
Reason
Float switch broken down for more than
25m continuously
Sensor broken down or short circuit for
more than 2m continuously
Sensor broken down or short circuit for
more than 2m continuously
Sensor broken down or short circuit for
more than 2m continuously
Sensor broken down or short circuit for
more than 2m continuously
CT check abnormal 3 times in 30m
High pressure switch acts 3 times in 30m
Communication abnormal for more than
4m continuously
Communication abnormal for more than
4m continuously
Outside signal broken down for more than
10s
Sensor broken down or short circuit for
more than 2m continuously
EEPROM data missing
Pressure switch or discharging protector
disconnected; or CN11 on indoor PCB
disconnected. The failure occurs only when
there is no outdoor PCB.
Detected temperature of discharge line is
higher than 120*
Indoor units operate in different modes
Sensor broken down or short circuit for
more than 2m continuously
Detected temperature of discharge line is
higher than 120*
Module overheat, overcurrent, short-circuit
Current sensor failure or compressor is not
started
