What is the Jet Cool function and how do I use it?

Jet Cool is a speed cooling function that operates the unit at super high fan speed in cooling mode for 30 minutes, automatically setting the room temperature to 18°C. Press the Jet Cool button to activate it, and press it again to cancel, which will return the unit to high fan speed in cooling mode. It is especially useful to cool the room in the shortest time during hot weather. Note that Jet Cool is not available in heat pump mode or neuro fuzzy mode. (Page 15)
