8-8. Low Temperature Cutff (Heating)

This function protect the compressor from being damaged due to flow back of the liquid refrigerant to the com- pressor when the outdoor temperature is very low.

Low ambient operation during heating can cause the outdoor heat exchanger to become super–cooled which may result in liquid back–flow. To protect the compressor from this condition, both compressor and outdoor fan stop if the outdoor temperature drops around 5°F. However, the indoor fan continues to operate even after the compressor has stopped. Note that standby lamp does not lights up during this period.
