5-3 Freeze Prevention (Cooling and Dry)
- 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 -1°C, the control circuit stops the compressor for at least 6 minutes. The compressor does not start
again until the temperature rises above 8°C or 6 minutes has elapsed.
