2. Error detection method
Anomalously low temperature
or high temperature (resistance)
is detected by indoor return air
temperature thermistor (ThI-A)
3. Condition of Error displayed
• When the temperature thermistor
detects -50°C or lower for
5 seconds continuously, the
compressor stops. After 3-minute
delay, the compressor starts again
automatically, but if this error
occurs again within 60 minutes
after the initial detection.
4. Presumable cause
• Defective return air
temperature thermistor
connector
• Defective return air
temperature thermistor
• Faulty indoor control PCB
