User guide
Function
It gives a selection whether to turn ON the unit directly or not from the external source (such as key holder in hotel rooms).
The selection can be made by pressing Cancel button of the wireless remote controller 3 times within 3 minutes of starting
the unit facing it towards the unit (This function availability depends on indoor unit model type.)
1. Normal mode (Factory set)
• Not to turn ON the unit directly from the external source.
On inserting the key inside the key holder, it activates the system.
Later on , the unit can be turned ON by the remote controller.
2.Automatic mode
• To turn ON the unit directly from the external source
On inserting the key inside the key holder, it automatically turns
ON the air conditioner. So no need to use remote controller.

However the unit can be turned off directly if the key is taken out of the key holder for both cases.
• In case of power failure the air conditioner will resume its similar operation before the power failure.
• In case power comes again after a power failure. Auto restart the unit auto magically operates to the previous operation
conditions.
