LOAD CONTROL DEVICE, LOAD CONTROL SYSTEM, AND LOAD CONTROL METHOD

A load control device includes a device that has a plurality of operation modes depending on applications and is electrically connected to a load. The device includes an operation mode determination circuit. The operation mode determination circuit is configured to: set a tentative operation mode indicating the operation mode before determination; obtain operation mode information regarding the operation mode via communication, the operation mode information including an error detection code for detecting an error of the tentative operation mode; determine whether or not a setting result of the tentative operation mode is correct using the error detection code; and determine the operation mode of the device based on a determination result.
