Abstract: A remote control unit of an air conditioning apparatus includes a display unit, a cursor-moving member, a confirmation member, and a controller. The display unit displays a menu and a cursor that indicates an item among a plurality of items inside the menu and is moved by the cursor-moving member when operated by a user. The confirmation member is configured to decide that the item is to be executed. The controller controls the display unit in response to the cursor-moving member or confirmation member being operated. The controller positions an item corresponding to a predetermined input at the top of the menu upon receiving the predetermined input.

Abstract: An indoor unit (1) is provided with an output control portion (35, 71) for controlling a cleaning signal output portion (33, 48) to output a cleaning signal when it is determined that the amount of dust in a dust storing portion (60, 90) has reached a predetermined first level, and when it is determined that the amount of dust in the dust storing portion (60, 90) has reached a second level that is higher than the first level.

Abstract: An air conditioning controller includes a storage component, a data receiving component configured to receive set numeric data, a display component configured to display data, and a control component. The storage component has stored operation explanation data, relationship explanation data, and setting layout display data stored therein. The stored operation explanation data defines operations of functions executed in the air conditioner. The relationship explanation data defines relationships between explanations of operations of functions and values that are set. The setting display layout data includes setting display region data and explanation display region data. The control component is configured to cause the set numeric data that the data receiving component has received to be displayed in a setting display region while causing the operation explanation data and the relationship explanation data to be displayed in an explanation display region in accordance with the setting display layout data.
