•
Refrigerant leak detection – The refrigerant leak detection function can better prevent the compressor
from being damaged by the leaked refrigerant or compressor overload.
•
Self-diagnosis Function – The air conditioner’s control board will shut off the unit if there is any abnormal
operation or parts failure and display a corresponding error code for the potential cause of the problem.
•
Compressor Crankcase Heater – Oil easily dissolves in refrigerant, especially in low temperature conditions.
The crankcase heating belt can heat the bottom of the compressor to avoid pumping out too much oil
with the refrigerant, which also protects the compressor.
•
Freezing protection – In heating mode, the set temperature can be set to 46°F (8°C) to prevent pipes, etc.
from freezing when the house is unoccupied for a long time severe cold weather.
