Abstract

PURPOSE:To make the terminal equipment small by allowing the terminal equipment to select individual control, group control and pattern control and using a common individual operation switch to control a load of the control terminal equipment at an optional address. CONSTITUTION:When a specific load is desired to be individually controlled by using an operation terminal equipment 2', a mode selection switch is set to the position of individual control and a channel number of the control terminal equipment connected to the load is selected fed by a channel number/number selection switch. In this case, a central control section 21 displays a number corresponding to a control terminal equipment specific address vertically in response to the operation of the switch. When the display reaches an address corresponding to the load and the individual control switch corresponding to the load number is operated, the central control section 21 reads a relevant specific address from a data storage section 22 and sends an interrupt signal to the central controller 1. The controller 1 generates control data used to control the load and sends the data to the control terminal equipment.
