Abstract

A multi-room controller for controlling a plurality of individual light controls, each associated with a room of a partitionable space. The individual light controls each control the light individually in the control'"'"'s room. An assignment panel associated with the multi-room controller is operable to link several individual light controls in a group under the control of a selected individual control within the group. This linking occurs when several rooms have been combined into a larger room and it is desirable to have uniform control of the lighting within the larger room. The multi-room controller is in communication with each individual light control and responsive to the assignment panel for transferring control of the group to the selected individual light control. In one operation mode, the lighting is controlled by a preselected individual control. In another mode, the lighting is controlled by any of the linked controls in the group. All linked controls mimic the last activated control.

Claims

1. A multi-room controller for controlling a plurality of individual light controls, each light control adapted to control directly lighting within an associated room of a partitionable space and to respond to other light controls that can indirectly control the lighting, comprising:

assignment means operable for linking individual light controls in a group for control by each individual control within the group; and

controller means in communication with each individual control and responsive to operation of the assignment means for enabling each individual light control within the group of linked controls upon activation to control the lighting within the rooms associated with the group,

the lighting thereby responsive to each of the linked individual light controls.

2. The multi-room controller of claim 1 including mode means for determining the selected individual control, the mode means determining in one mode that the selected control is an individual control preselected for each group of linked controls and determining in another mode that the selected control is the individual control last activated within the group.

3. The multi-room controller of claim 1 in which the controller means includes memory means for storing information identifying a group of linked controls and the assignment means comprises a plurality of switches associated with the memory means that each select a corresponding group of linked controls, the switches representing rooms to be combined.

4. The multi-room controller of claim 3. in which the memory means is nonvolatile and reprogrammable to change the identification of the linked controls within a group selected by a switch.

5. The multi-room controller of claim 1 in which the assignment means comprises a plurality of multiple setting switches, each corresponding to a room and each containing settings corresponding to rooms within the partitionable space, the lighting in each room controlled by the individual light control set in the corresponding switch, a group of individual controls linked by setting the corresponding switches to the same setting.

6. The multi-room control of claim 1 in which the controller means comprises:

I/O means for two-way communication with the individual light controls and the assignment means;

memory means for storing information received through the I/O means indicating the groups of individual controls linked and their present settings; and

central processing means for transmitting the setting of the individual light control that controls a group to all the controls within the group.

7. The multi-room controller of claim 6 in which the I/O means is adapted to communicate serially with the individual light controls over a twisted pair of wires.

8. A lighting control system for controlling the lighting in multiple rooms of a partitionable space, comprising:

a plurality of individual light controls each having switch means for controlling directly the lighting individually in an associated room of the space and having I/O means for communicating the switch settings to other individual light controls for indirect control of lighting in other rooms;

assignment means operable for linking individual light controls in a group for control by each individual control within the group; and

controller means in communication with each individual control and responsive to operation of the assignment means for receiving the switch settings and communicating said switch settings to the other individual light controls within the group to enable each individual light control to control directly or indirectly via its switch means the lighting within the rooms associated with the groups,

the lighting thereby responsive to each of the switch means as it is activated.

9. The lighting control system of claim 8 in which the controller means includes mode means for determining that the selected control is an individual control preselected for each group of linked controls.

10. The lighting control system of claim 9 in which the controller means includes mode means for determining that the selected control is the individual control last activated within the group of linked controls.

11. The lighting control system of claim 8 in which the controller means includes memory means for storing information identifing the linked controls, the individual light controls linked by the assignment means.

12. The lighting control system of claim 11 including means for reprogramming the memory means on-site.

13. The lighting control system of claim 8 including optocoupling means for optically coupling the controller means to the assignment means and to each of the individual light controls.

14. An individual light control for setting the lighting in a room, comprising:

central processing means for controlling directly the light intensity of the associated lights in the room; and

I/O means for communicating light intensity information between the central processing means and other central processing means of other individual light controls to enable the individual light control to mimic the setting of the other individual controls.

15. The individual light control of claim 14 in which the I/O means is adapted to communicate serially with other individual light controls over a twisted pair of wires.
