Split air conditioner operation with R-410A refrigerant (inverter).

 The compressor may not operate if the ambient temperature is within the compressor-ON range.

 Description: The compressor does not run while the compressor start delay timer (3-minute timer) runs. The same phenomenon is observed after the power source has been turned on because of the timer operation.

The increase in the speed of the compressor motor stops after about 30 seconds from the start of operation, and then the speed of the compressor motor speed will increase after about 30 seconds.

 Description For the compressor to operate smoothly, its speed is restricted to a maximum of 33 rps for 2 minutes and a maximum of 57 rps for 2 to 4 minutes, after the start of the operation.

The adjusted value of the remote control must be below room temperature.

Description If the set value is above room temperature, cooling operation is not carried out. And check whether the battery in the remote control is exhausted or not.

In AUTO mode, the operating mode changes.

Description: After selecting the Cooling or Heating mode, select the operating mode again if the compressor remains stopped for 15 minutes.

In HEATING mode, the compressor motor speed does not increase or decrease until the temperature reaches the set temperature.

Description: The compressor motor speed may decrease due to the high-temperature release control (release protection operation by increasing the temperature of an internal heat exchanger) or by the current release control.
