Presets: Defined vs. Undefined Levels

Understanding the meaning of the terms "defined" and "undefined", as used in the context of levels in the Radia lighting system, is helpful. Each dimmer on the Radia has a TRUE/FALSE status associated with it that is referred to as "defined". The state of the defined status is used when saving presets so that the Radia knows which dimmers are to be affected when the preset is recalled. Upon power-up, all the dimmers are in the undefined state. As soon as any of the dimmers changes state (i.e. the level changes), the dimmer automatically becomes defined. Upon recording a preset, the Radia will save all of the dimmer levels that are defined at that time and only affect those when the preset is recalled.

For example, if all the dimmers are undefined and dimmers 1 and 3 get their levels changed, the Radia will save the levels of 1 and 3 only when told to record preset 7. When preset 7 is recalled, only dimmers 1 and 3 will be adjusted. The other dimmers (2, 4, 5 and 6) are said to be undefined for that preset.

Preset Status

Channels 1-128 reflect the current status of active presets. A preset is "active" for as long as its associated dimmers (circuits) remain at the levels associated with the preset. For example, assume the following presets exist in the Radia:

Preset #

Preset #		Dimmer #1	Dimmer #2	Dimmer #3	Dimmer #4	Dimmer #5	Dimmer #6

1	– Meeting (A)	100%	50%	100%

2	– Presentation (A)	50%	25%	50%

3	– Off (A)	0%	0%	0%

4	– Meeting (B)				100%	50%	100%

5	– Presentation (B)				50%	25%	50%

6	– Off (B)				0%	0%	0%

7	– Cleaning (A&B)	100%	100%	100%	100%	100%	100%

8	– Night (A&B)	0%	0%	0%	0%	0%	0%

Also, the configuration of the Radia is such that dimmers 1-3 are controlling lights in room A (a conference room) and dimmers 4-6 are controlling lights in room B (another conference room). In each of these room is a

3-button wall-mounted control panel that provides control of the local lights:

The room A panel has the following mapping between buttons and presets and feedback: Meeting Mode -> Preset 1 -> Feedback from channel 1

Presentation Mode -> Preset 2 -> Feedback from channel 2 Off -> Preset 3 -> Feedback from channel 3
