2. Error detection method
Detection of anomalously
low temperature (resistance)
on outdoor air temperature
thermistor
3. Condition of Error displayed
• When the temperature thermistor
detects -45(-55)°C or lower for
5 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 -45(-55)°C or lower is detected
for 5 seconds continuously within 20
second after compressor ON.
Note (1) Value in ( ) are for the models
SRC 40-60.
4. Presumable cause
• Defective outdoor control
PCB
• Broken thermistor harness or
temperature sensing section
(Check molding.)
• Disconnected wire connection
(connector)
Note:
Note (1) Value in
is for the models SRC40-60.
