2. Error detection method
Anomalously low temperature
or high temperature (resistance)
is detected by indoor return air
temperature sensor (Th1)
3.
Condition of Error displayed
•
When the temperature thermistor
detects -45°C or lower for 15
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.
