Screen zone
Lighting near the presentation screen. Review its effect on the displayed image and viewing comfort.
ILLUSTRATIVE / CONTROL INTENT
One room.
A shared control brief.

ILLUSTRATIVE / FOR PROJECT DISCUSSION
Meeting room / MR-01
A sample lighting-control brief for a room with a presentation screen, meeting table and daylight perimeter.
This is a discussion example, not a completed project or installation specification. Equipment models, lighting levels, delays and responsibilities remain to be agreed. Emergency and life-safety systems are outside this example.
01 / Room and zone names
Give every lighting group a clear name.
Use the same room and zone references in drawings, the scene schedule and the final configuration records.
Table zone
Lighting for reading and meeting tasks. Agree the required response for work and presentation scenes.
Daylight perimeter
Lighting alongside the window area. Review daylight response and its interaction with manual scene selection.
These labels identify functional zones. They are not DALI addresses, group numbers or KNX group addresses. Final luminaire assignments and addresses belong in the agreed project schedule.
02 / Scene schedule
Four responses to agree.
The everyday scene uses the table and daylight zones; presentation also changes the screen zone. Confirm exactly which groups each scene controls.
| Scene | Trigger | Lighting response | To agree |
|---|---|---|---|
| Everyday work | Presence detected | Task lighting follows the agreed setpoint; perimeter lighting responds to daylight. | Sensor coverage and setpoint |
| Presentation | Presentation scene selected | Screen-zone lighting dims while the table retains reading light. | Scene priority and glare |
| Cleaning | Authorised manual selection | Selected lighting groups enter the cleaning scene. | Override and exit behaviour |
| Unoccupied | Agreed vacancy period reached | Relevant lighting groups switch off after the delay. | Timeout and manual override |
Light levels, delays and priorities are defined for the room, users and local project requirements. No fixed energy-saving result is implied.
Priority is a design decision. Agree how manual scene selection interacts with presence and daylight inputs, how cleaning mode ends, and when normal automatic operation resumes. The table does not prescribe an override hierarchy.
03 / Interface review
Resolve the equipment questions.
Record the selected models, evidence and open decisions before treating the brief as ready for implementation.
- Luminaires and drivers
- Confirm the exact models, dimming interfaces and intended operating range. Identify any existing fittings that need changes.
- KNX–DALI gateway
- Check support for the required groups, scene commands and feedback. Review device quantities and addressing with the selected equipment.
- Sensors and wall controls
- Confirm device interfaces, proposed locations, sensing coverage, scene labels and which device provides the room logic.
- Colour-temperature control
- This example covers brightness control. If tunable white is requested, separately check the required DT8 colour-control support in the drivers, controller and gateway.
- Other building systems
- Record any BMS, shading or HVAC coordination requested. Agree the supported interface, points and responsibilities separately.
- Project documents
- The local team confirms applicable site and product requirements. List the equipment documents and installation information needed for its review.
04 / Site tests to agree
Check the room against the brief.
The local project team turns these prompts into a site test plan. Record the outcome, reviewer and any follow-up for each item.
- Zone identification: confirm that the installed fittings, wall-control labels and zone schedule refer to the same groups.
- Everyday work: observe the agreed response to presence and daylight, including sensor coverage and the room's working conditions.
- Presentation: select the scene and review the screen and table zones with the actual display in use.
- Cleaning: confirm who can select the scene, which groups respond and how the room leaves that mode.
- Unoccupied: check the agreed vacancy delay, manual override and return-to-use behaviour.
- Transitions and exceptions: review scene changes and define the required response after supply or communication interruptions in the project test plan.
Acceptance criteria and testing methods are set for the project. This checklist does not define electrical testing or safety procedures.
05 / Handover checklist
Leave a clear record.
Agree which final files are included, who owns them and how the installer and owner will receive them.
- Final room, zone and scene schedule with agreed settings and revision identification.
- Equipment list, interface decisions and the relevant manufacturer documentation.
- KNX group-address and DALI addressing/group records for the implemented system.
- Configuration or project-file backups included in the agreed support scope.
- Completed functional test record, unresolved issues and responsible contacts.
- Room operating notes, maintenance contacts and arrangements for future changes.
