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.

Claims

1. 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.

2. The air-conditioning remote controller of claim 1, wherein the control unit changes the upper limit, the lower limit, or both the upper limit and the lower limit designated by the setting target in accordance with an operation of the set-temperature increase button or the set-temperature decrease button.

3. The air-conditioning remote controller of claim 1, wherein the control unit makes the display section display the upper limit and the lower limit when the setback control starts, makes the display section display the upper limit, the lower limit, or both the upper limit and the lower limit in a blinking manner in accordance with the setting target during the setback control, and changes the setting target in accordance with an operation for changing the setting target during the setback control.

4. The air-conditioning remote controller of claim 1, wherein if an operation for changing the setting target is performed during the setback control, the control unit changes the setting target in accordance with an order in which the upper limit, the lower limit, and both the upper limit and the lower limit are set.

5. The air-conditioning remote controller of claim 1, wherein when a signal is not received from the operable section for a predetermined time period during the setback control, the control unit ends a process for changing the setting target.

6. An air-conditioning system comprising:

the air-conditioning remote controller of claim 1; and

an air-conditioning apparatus controlled by a control command from the air-conditioning remote controller.
