Abstract: An air-conditioning remote controller includes a display section, an operable section, a memory, a transmitter unit, and a processor. The operable section includes a set-temperature increase button and a set-temperature decrease button. In the memory, information designating an upper limit, a lower limit, or both the upper limit and the lower limit as a setting target in setback control is set. The processor makes the display section display a set temperature or temperatures designated by the setting target set in the memory, changes the set temperature or temperatures designated by the setting target on the basis of an operation result of one of or both of the set-temperature increase button and the set-temperature decrease button, and transmits the changed result to the transmitter unit.
