4-2 Freeze Prevention
This function prevents freezing of the indoor heat exchange coil.
When the compressor has been running for 6 minutes or more and the temperature of the indoor heat
exchange coil falls below –0.8°C, the control circuit stops the compressor for at least 3 minutes. The
compressor does not start again until the temperature rises above 8°C or 6 minutes has elapsed.
