Abstract: A controller of a central air conditioning system controls a damper provided for a first target space according to a target temperature. After a predetermined period of time has elapsed since control of the damper provided for the first target space was started according to the target temperature, the controller determines: an association between the controlled damper and the temperature sensor that has detected the changed temperature is correct when a changed temperature detected by a temperature sensor approaches the target temperature in the first target space; and the association between the controlled damper and the temperature sensor that has detected the changed temperature is incorrect when a temperature detected by the temperature sensor does not approach the target temperature in the first target space. Then, the controller outputs a result of determination.

Abstract: A switch includes a manipulation display, a processor, and an outputter. The manipulation display includes a manipulation section and a display section. The processor is configured to select one of a first state for giving an instruction as to operation of a specific device and a second state for giving an instruction as to operation of a prescribed device which is determined so as to correspond to a specific scene. The outputter is configured to output an instruction signal according to the first state or the second state selected by the processor when the manipulation display is manipulated. The processor is configured to select one of the first state and the second state in response to a specific manipulation performed on the manipulation display.
