Abstract:
1. An electric device for changing a demand response (DR) control level, comprising: a processor, comprising: a memory unit to store one of a plurality of DR control levels each corresponding to a power rate level as a start level of the power saving operation; a communication unit to receive a current power rate and a current power rate level related to the current power rate from a power provider; a user interface which, upon receiving a request for changing a DR control level to a desired DR control level from a user, displays a list of the stored DR control levels and receives the desired DR control level from the user; and a controller to compare the current power rate level with the desired DR control level from the plurality of DR control levels, and to determine whether to perform a power saving operation, wherein the controller sets a product recommended DR control level pre-stored in the memory unit when the product is manufactured to the start level of the power saving operation, and sets the desired DR control level to the start level of the power saving operation upon receiving a request for changing the DR control level to the desired DR control level from the user interface.
