properly ?
Regarding the characteristics of
the thermistor, see the following chart.

2. Error detection method
Detection of anomalously low
temperature (resistance)
of Thi-R1, R2, R3.
3 . Condition of error displayed
• If -40ºC 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 70ºC or higher is
detected for 5 seconds
continuously.
4. Presumable cause
