Fault description
Outdoor environment
temperature sensor short
circuit or open circuit
The outdoor coil temperature
sensor short circuit or open circuit
EEprom Data error or EE chip fault
Refrigeration indoor coil
temperature is too low or heating
the indoor coil temperature too high
Outdoor continuously for 2 minutes
without receipt of indoor
communication data
Three phase power supply wiring
line sequence error
Compressor overheating protector
tripping
Too high system pressure leads to
high pressure switch tripping or
pressure sensors to detect the
pressure too high to achieve
shutdown protection pressure
System low pressure causing low
pressure switch tripping or pressure
sensors to detect the pressure is too
low to achieve the shutdown
