9. Electrical Control Functions 

Anti-freezed protection

：

 

After running for 9 minutes from compressor startup, the unit will check if the indoor coil 

temperature is below 0

℃

, the outdoor fan motor will stop running. 

After the compressor stops, if the below conditions can be met, the compressor and the outdoor fan 

motor will begin to run again: 

1.Shutoff time over 3 minutes 

2.Indoor coil temperature up to over 7

℃

 

3-minute protection of compressor when startup 

Once the compressor stops running, you can restart up only after 3 minutes. When the unit 

powered off in operation, if the shutoff time is below 3 minutes, it will be 3 minutes at least after 

powered on when the compressor starts up again. Powered on for the first time, there is no 

3-minutes delay protection. 

Auto defrosting function 

1) Starting condition 

The unit is in heat mode, and the compressor runs for 35 minutes continuously. 

The compressor has run totally for 45 minutes, and the compressor runs for over 5 minutes 

continuously. 

If either of the above conditions is met, and the indoor receives the defrosting signal from the 

outdoor unit, the unit begins to defrost and send the signal to outdoor. 

2) Quit condition 

The outdoor receives the signal to quit from the defrost or the defrosting time is over 12 minutes, 

the defrost will be over and send the relative signal to the outdoor. 

Temperature cutoff protection

：

 

When the indoor coil temperature is over 6

8

℃

 for 10 seconds, the compressor and the outdoor fan 

motor will stop. When the compressor has stopped for 3 minutes and when the coil temperature is 

below 

46

℃

, the compressor and the outdoor fan motor will operate again. 

Anti cold air protection in heat mode

：

 

If it is the first time in heat mode or the defrost is over, when the indoor coil temperature is below 28
