12.4. Auto OFF/ON Button

  • 

The “Auto OFF/ON” button is used to operate the air conditioner if remote control is misplaced or malfunctioning.

  • 

Auto operation is started once “Auto OFF/ON” button is pressed.

  • 

Forced cooling operation is possible by pressing the “Auto OFF/ON” button for more than 5 seconds where “beep” sound is
heard, then release the button.

  • 

By continuously pressing the “Auto OFF/ON” button, it will enable standby states for Forced Heating Operation, Various Setting
Mode and Individual Correspondence Mode. At standby state, the unit still operates with Forced Cooling Operation.

  • 

Press “Timer Decrement” button of remote control for 5 seconds to activate the standby mode, where “beep” sound is heard.

  • 

In Various Setting Mode, the unit captures remote control transmission code when “Check” button is pressed.

  • 

In Individual Correspondence Mode, press “Check” button at remote control to enter remote control signal receiving sound
selection mode.

Press “Auto OFF/ON” button to trigger the remote control signal receiving sound.

  − 

Short “Beep”: Turn OFF remote control signal receiving sound.
