2. Error detection method
Detection of anomalously low
temperature (resistance) on
the outdoor heat exchanger
temperature thermistor
3. Condition of Error displayed
• When the temperature thermistor
detects -50(-55)°C or lower for
20 seconds continuously within 2
minutes to 2 minutes 20 seconds
after the compressor ON, the
compressor stops. After 3-minutes
delay, the compressor starts again
automatically, but if this anomalous
temperature is detected 3 times
within 40 minutes.
• When -50(-55)°C or lower is detected for
5 seconds continuously within 20 second
after compressor ON.
Note (1) Value in ( ) are for the models
SRC40-60.
4. Presumable cause
• Defective outdoor control
PCB
• Broken thermistor harness or
temperature sensing section
• Disconnected wire connection
(connector)
