Operation of air conditioner: Fan speed setting is not allowed in AUTO or DRY mode
Explanation: The speed of the indoor fan is set to low in DRY mode. Fan speed of 3 steps is selected automatically in AUTO mode
Operation of air conditioner: Compressor stops operation intermittently in DRY mode
Explanation: Compressor operation is automatically controlled in DRY mode depending on the room temperature and humidity
Operation of air conditioner: Compressor of the outdoor unit is operating although it is turned off in HEAT mode
Explanation: When the unit is turned off while de-ice is activated, the compressor continues operation for up to 10 minutes (maximum) until the deice is completed
Operation of air conditioner: Timer indicator lamp lights up and the air conditioner does not operate
Explanation: Timer is being activated and the unit is in ready mode. The unit operates normally if the timer operation is cancelled
Operation of air conditioner: The compressor and indoor fan stop intermittently in HEAT mode
Explanation: The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protect the compressor from overheated air in HEAT mode
Operation of air conditioner: Indoor fan and outdoor fan stop intermittently in HEAT mode
Explanation: The compressor operates in a reverse cycle to remove exterior ice in HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heat operation
Operation of air conditioner: The compressor stops intermittently in COOL mode or DRY mode, and fan speed of the indoor unit decreases
Explanation: The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature.
