The LIOB‑591 fan coil controller provides the basis for a revolutionary room automation system based on IP, which seamlessly integrates with native BACnet/IP networks at the controller level. Together with the L‑STUDIO software, room control solutions can be created with little effort. Integral parts of the room control system are a web‑based room operation via an LWEB‑802/803 dashboard and the automatic generation of graphics for the L‑VIS Touch Panel for local operation. LIOB‑591 Controllers implement the BACnet Building Controller (B-BC) profile and are BTL certified.
Our room controllers provide all common interfaces and a large number of physical I/Os for room automation projects. DALI lamps and DALI sensors are connected to the DALI interface with an integrated DALI power supply. Up to 16 SMI sunblind motors connect to an external SMI interface. Belimo valves connect to the external MP‑Bus interface. BACnet MS/TP devices connect to the RS‑485 interface, which can also be configured as a Modbus RTU interface to connect Modbus devices like energy meters or ekey finger scanners for access control or to connect the L‑STAT Room Control Unit. EnOcean devices connect to the external EnOcean interface. Dual Ethernet ports allow daisy-chaining of LIOB-591 controllers in a ring topology and provide BACnet/IP, Modbus/IP and OPC communication.
Optionally, the LIOB-591 can communicate via wireless LAN through the LWLAN‑800 wireless adapter connected to the USB port. 20 universal I/Os, one 1250 W and three 300 W TRIAC outputs connect various physical input and output devices. Our room automation library provides pre-built function modules for all lighting, heating, cooling, ventilation, sunblinds and access control via finger scanners. Built‑in SSL encryption ensures secure operation of the room automation system.
All typical room functions are supported:
- Lighting control with constant light controller
- Sunblind control with angle adjustment and year shade progression
- Temperature control for heating, cooling, and ventilation
- Occupancy detection
- Window monitoring and window contact
