7-2. Freeze Prevention<br />
● This function prevents freezing of the indoor heat exchange coil.<br />
● When the compressor has been running for 10 minutes or more and the temperature of the indoor heat<br />
exchange coil falls below –1°C, the control circuit stops the compressor for at least 6 minutes. The compressor<br />
does not start again until the temperature rises above 8°C or 6 minutes has elapsed.<br />
