After power on again and the AC will restart 3 minutes later due to the function of 3 minutes protection

Solution

Some modes have power off compensation function, if you set this function, when power on again, the unit will continue the previous setting.
The power off compensation function setting method is on the condition that your remote have a SLEEP button.
Press SLEEP button 10 times in 10 seconds, if you hear 4 "Pi" sound this means the function be set.
If you press SLEEP button 10 times in 10 seconds, and hear 2 "Pi" sound this means the function be canceled.
If your remote doesn't have SLEEP button, please dial our hot line for help.
