5-4. 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 2.4°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.
5-5. Compressor Overcurrent Protection (Cooling, Dry and Heating)
●
This function prevents the compressor from being damaged by overcurrent.
●
When the compressor current exceeds either H1(A) for 2 seconds or H2(A) for 8 seconds, both compressor
and outdoor fan stop (Trip). At the same time, operation lamp in front of the indoor unit flashes.
●
After 3 minutes, this function automatically releases and resumes operation until tripping repeats 8 times.
If the tripping repeats 9 times or more, the unit stops its operation.
The compressor current shown as H1 and H2 in the chart differ by models.
