Air-conditioning remote controller and air-conditioning system

An air-conditioning remote controller comprising:

• a display section that displays information related to an operational status of an air-conditioning apparatus;
• an operable section for controlling the operational status of the air-conditioning apparatus;
• a storage unit that stores information related to set temperatures according to operation modes of the air-conditioning apparatus;
• a transmitter unit that transmits a command related to the operational status of the air-conditioning apparatus to the air-conditioning apparatus;
• and
• a control unit that changes the information related to the set temperatures and controls the display section and the transmitter unit on the basis of an operation performed on the operable section,
• wherein the operable section includes a set-temperature increase button that generates an operation signal for increasing each set temperature, and a set-temperature decrease button that generates an operation signal for decreasing each set temperature,
• wherein, in the storage unit, information designating an upper limit, a lower limit, or both the upper limit and the lower limit as a setting target in setback control, which is one of the operation modes, in which air-conditioning is performed within two set temperatures, which are the upper limit and the lower limit, is set, and
• wherein the control unit makes the display section display the set temperature or temperatures designated by the setting target set in the storage unit, 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 a changed result to the transmitter unit.
