• Refrigerant Leakage Detect Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
• Anti-cold Air Function Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
• Low Ambient Heating With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The system can run heating operation even when the outdoor ambient temperature is down to -13°F.
• Follow Me Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
