Abstract
Disclosed is a centralized home appliances simultaneous control system consisting of controller(s) and terminal units associated with home electric appliances. Setting of batch control is done in a centralized manner on the controller(s) and it is stored in the memory provided in the controller(s), instead of being done on the individual terminal units. The settings stored in the controller's memory are sent via a communication medium to the memory in each terminal unit, and the setup status of each terminal unit is sent back to the controller(s) for the purpose of monitoring with reference to the contents of the controller's memory. A batch control command signal is issued from the controller(s) to the terminal units, which then responds to control the operation of the associated electric appliances in accordance to the batch control plan corresponding to the command held in the memory of the terminal units.
