[Nyororin]

The buttons on the outer menu (I`ll get to the inner in a few minutes):

Button with up and down adjusts something. On it`s own, I imagine it adjusts the temperature. In a menu (or timer) it will change the setting there.
Orange is on and off.

Right side, buttons with lines.
With the grey line - humidity setting adjustment. (50% is best, you have it set on 40%, that`s really too low.)
Dark blue line - Dehumidifying AC
Green line - dehumidifier menu
Red line - Heater

Left side, from top to bottom.
Triple air clean (Could be either an air filter, drawing fresh air in outside, ion something or other, or all 3 together. Depends on the model.)
Continual ventilation
Wind area (I`m guessing it`s to change the aim of the airflow, but as it`s a feature name and not an exact description of what it does it`s a guess)
High power (Usually uses a ton of electricity.)

The two rounded buttons at the bottom are for setting the time. Left is to set the timer to turn the air conditioner on, the right to set a time for it to turn off.
