An air-conditioning controller (1) comprises an arrow key (11), a control unit (70), and a liquid crystal display unit (75); and receives operation input to an air-conditioning apparatus (100) capableof a plurality of airflow direction settings. The arrow key (11) is a key for switching among the airflow direction settings. The control unit (70) determines a currently selected airflow direction setting on the basis of the operation input inputted via the arrow key (11). The liquid crystal display unit (75) simultaneously displays an image (P0 - P4, Ps) and a character (L0 - L4, Ls) corresponding to the airflow direction setting determined by the control unit (70) to be currently selected. The operability of the air-conditioning controller (1) with respect to the airflow direction settingsof the air-conditioning apparatus (100) is thereby improved.
