Diagnosis
Countermeasure
Is
the connector of
thermistor connected
properly ?
Regarding the characteristics of
the thermistor, see the following chart
Temperature-resistance characreristics of indoor
return air temperature thermistor (Thi-A)
Are
the characteristics
of thermistor OK?
*1
NO
NO
YES
YES
*1 Check several times to prove any poor connection

2. Error detection method
Detection of anomalously low
temperature (resistance) of
Thi-A
3. Condition of error displayed
• If -50°C or lower is
detected for 5 seconds
continuously, compressor
stops. After 3-minutes delay
the compressor is restarted
automatically, but if this
anomaly occurs again within
60 minutes after the initial
detection.
• Or if 48°C or higher is
detected for 5 seconds
continuously.
4. Presumable cause
• Anomalous connection of
indoor return air temperature
thermistor
• Indoor return air temperature
thermistor anomaly
• Indoor control PCB anomaly
