LUMEN / KNX BUILDING AUTOMATION

KNX building automation, engineered and documented.

We design, install and program KNX through ETS for lighting, DALI, HVAC, shading, sensors, energy and touch panels, with defined BMS integration.

KNX SYSTEM ARCHITECTURE

KNX system architecture

KNX connects field devices, room controls and upper-level systems through one documented, distributed architecture.

KNX system architecture showing the power supply, KNX TP bus, sensors, thermostat, keypad, actuators, IP network, ETS engineering and BMS integration gateway
Color-coded paths distinguish the KNX TP bus, IP network and BMS integration protocol.
Core KNX control functions

Six core scopes engineered around the project.

Each scope follows approved circuits, devices and operating interfaces rather than an undefined generic package.

Lighting and DALI control
01

Lighting and DALI control

Organize lighting circuits into channels, groups and scenes, using KNX-DALI gateways when luminaires require addressing or dimming.

  • Switching, dimming and lighting groups
  • KNX-DALI gateways and luminaire addressing
  • Scenes, schedules and daylight response
HVAC room control
02

HVAC room control

Interface room thermostats, fan-coil units, valves and fan speeds according to the approved HVAC equipment and control method.

  • Room thermostats and FCU control
  • Occupied, away and setback setpoints
  • Documented interfaces for each equipment type
Shading and blinds
03

Shading and blinds

Operate curtains and blinds individually or in groups, with time, daylight and scene-based control where required.

  • Actuator channels and group control
  • Sheer, blackout and defined stop positions
  • Schedules, sensors and scene logic
Sensors and occupancy
04

Sensors and occupancy

Use motion, presence, daylight, temperature and air-quality inputs to execute defined automation logic in each space.

  • Occupancy, presence and daylight
  • Temperature and air-quality inputs
  • Value-based local operating logic
Energy monitoring
05

Energy monitoring

Collect readings from compatible meters or measuring actuators and expose selected consumption data through KNX or the BMS layer.

  • Energy and zone-consumption readings
  • Defined limits and device-supported alerts
  • Approved points exposed to BMS when required
Touch panels and user interfaces
06

Touch panels and user interfaces

Provide clear room and scene control through keypads and touch panels, with optional application or remote access under defined permissions.

  • Keypads and touch panels
  • Organized pages and scene matrices
  • Local functions independent of the internet
Practical operating scenarios

Each scene groups defined commands into one action.

Every function and value is reviewed before the scene matrix is approved and programmed in ETS.

01

Arrival

Set defined lighting levels, room climate and shading based on time and user permissions.

02

Meeting & presentation

Dim lighting, close shades and adjust room temperature from one command while retaining manual control.

03

Away

Switch off nonessential circuits, apply HVAC setback and move selected shading to the approved position.

04

Night & energy

Reduce nonessential loads and retain only required paths using schedules and sensor conditions.

Where KNX is used

One standard, with functions tailored to the building.

Device distribution, scenes and user interfaces follow the operating requirements of each sector.

Luxury residences

Luxury residences

Distributed room and zone control for lighting, climate and shading through consistent, clear interfaces.

Hotels & hospitality

Hotels & hospitality

Guest-room, corridor and common-area functions with approved operating interfaces.

Offices & meeting rooms

Offices & meeting rooms

Meeting, presentation and away scenes with occupancy sensors and area schedules.

Commercial buildings

Commercial buildings

Zoned lighting, climate and shading with selected monitoring points exposed to the BMS.

KNX and BMS: integrated, not duplicated

Distributed local control and centralized supervision.

The design preserves room-level independence and exposes only approved points required by the facility operator.

KNX

Local control layer

Keypads, sensors, actuators and thermostats execute lighting, shading, climate and scene functions within each area.

BMS

Central supervision layer

Receives agreed states, alarms and values, and applies central schedules or commands through a defined points list.

From design to handover

A documented KNX delivery path.

The scope covers engineering, programming, testing and backups—not device operation alone.

01

Design

Define functions, zones and topology.

02

Device selection

Approve sensors, keypads, actuators and gateways.

03

ETS programming

Create the project, addresses and device parameters.

04

Group Addresses

Build group structure and link communication objects.

05

Scene logic

Define the scene matrix and operating conditions.

06

Integration

Connect DALI, HVAC and BMS within documented boundaries.

07

Testing

Verify channels, sensors and field responses.

08

Commissioning

Run the system and tune values on site.

09

Documentation

Deliver topology, address and channel schedules, and backups.

10

Handover

Train users and deliver the ETS project backup and warranty.
