Next to the card holder for the electricity is the control panel for the air conditioning. This shows the temperature at which the air conditioning is set. Below is a brief explanation of how to set the air conditioning.
Button a: This is a small button on the top of the control panel. If you press this once, the air conditioning will turn off. Off will also appear on the screen and the screen backlight will turn off. If you want to turn the air conditioning back on, press the button again.
Button b: You don't need to do anything with this. This is to change all the settings in the air conditioner.
Button c: If you press this, the temperature will become colder. This is also on your screen.
Button d: When you press this, the temperature will become warm. This is also on your screen.
