●Display conditions

If the temperature sensed by the thermistor is –30ºC or lower continu- ously for 5 seconds between 2 minutes and 2 minutes 20 seconds after the compressor goes ON, the compressor stops. After a 3 minute delay, the compressor restarts. If this state is detected 3 times in 40 (60) min-

utes.
