Comprehensive Building Management

LWEB-900 integrates and manages all building automation systems, including HVAC, lighting, security, energy, and more, from a central point, allowing for holistic control of the building.

Scalable and Modular Design

The system is scalable, supporting small buildings as well as large multi-site or campus-wide installations. Its modular design allows users to easily expand or adapt the system as the building's needs evolve.

Graphical User Interface (GUI)

The system provides a user-friendly, web-based graphical interface that allows operators to monitor and control all building systems in real-time. It offers customizable dashboards with dynamic graphics, alarms, and trending data.

Cross-System Integration

LWEB-900 is compatible with a wide range of communication protocols, including BACnet, KNX, Modbus, LON, DALI, and M-Bus, ensuring seamless integration with third-party devices and systems.

DALI Sensors

The L-DALI Controllers support the integration of DALI-2 multi-sensors for presence detection and light level recognition. In addition to the LOYTEC multi-sensors LDALI-MS2-BT/MS3-BT/MS4-BT, DALI-2 sensors of many well-known manufacturers can be used. For asset tracking in office buildings with the LOYTEC multi-sensors (LDALI-MSx-BT), a LIC-ASSET license is required.

DALI Buttons

For manual operation, DALI-2 push button couplers, like the LDALI-BM2, DALI-2 operation panels and IR remote controls can be integrated into the system. Their functionality can be configured individually.

DALI Relay Modules

Standard loads in the power grid can be controlled via DALI using DALI relay modules, like the LDALI-RM5 / LDALI-RM6 /LDALI-RM8.
