The control method controlled by the power management network differs according to the type of electrical appliances. If there are a plurality of electrical appliances of the same type, a unique identification number is required because there may be confusion in executing the control command unless the distinction is made.

In other words, the cooking appliance has a control method for cooking and thawing, the refrigerator has a control method for rapid cooling and defrosting operation, and the air conditioner has a control method such as dehumidification function, cooling function and heating function. The method is different, because it can be applied to the same control method for the same kind of electrical appliances to prevent crosstalk.

When the code application process is completed, the electrical product is registered in the power management network (S410).

Then, according to the user's selection, it is determined whether there is a request to register a new registered electric product equipped with the communication modem with respect to a power management program operated by an operating entity such as a power company (S411).

In this case, the power management program is a program for controlling electric products in order to adjust power rates or power consumption according to time zones.

If there is a request for registration, the power management program operator notifies the information on the newly registered electrical appliances, and notifies the power management program registration application of the product (S412).

Thus, the electrical appliances newly registered in the power management network become the control target of the power management program.
