Room automation plays an important role in operating a building energy efficiently. The degree of flexibility for creating new room situations, what is particularly important for office and administration buildings and is frequently required by building owners already in the earliest stage of planning, is defined.
However, there is more than efficiency features and flexibility whereupon room automation systems have to respond. Also for energy consumers in a room like sun blinds, lighting, valve actuators, various control options, and requirements are available nowadays.
Moreover, it is the ever increasing demand for virtual room control solutions which causes the next question to be raised: How to create a solution for integrating IP networks of IT and building automation, everyone (both IT and building automation departments) can live with? How much emphasis is placed on IT security in building automation networks in general? In times of bugging scandals, an increasingly relevant question!
The LOYTEC Solution
With the LROC-40x room controllers, LOYTEC provides a solution that eliminates all concerns about requirements and questions described above. Embedded in a compact sheet-steel housing for installation in suspended ceilings or in raised floors, the room controllers feature onboard interfaces to BACnet (IP and MS/TP), LON-IP, KNX (IP and TP1), Modbus (TCP and RTU, Master or Slave), OPC, DALI, SMI, MP-Bus and EnOcean. Complicated and cost intensive gateway solutions, e.g. for the integration in a building management system, are no longer necessary. For the physical connection of consumers, a well-planned constellation of in- and outputs (I/Os) is available. The built-in web server provides customer specific graphics for operation and visualizations of floor plans that can be operated as HTML5 pages via an arbitrary web browser or via a Windows PC. The integration into LOYTEC LWEB-900 Building Management System and connectivity to systems of other manufacturers are easily possible, as all standard protocols are supported.
Moreover, all models feature communication via SSL secured web services allowing a level of security that is equal to popular IT security mechanisms.
Depending on the model, each controller can handle up to 16 rooms respectively room segments. Thereby, the entire feature set to reach maximum energy efficiency is available:
- lighting control with constant light controller
- sun blind control with sun tracking
- temperature control for heating, cooling and ventilation
- occupancy detection
- window monitoring
- scheduling
- alarming
- trending
All parameters and complete axis flexibility are also part of LOYTEC's prefabricated segment functions that are fully independent of the hardware thanks to IEC61499 technology. Thus, each segment receives a room ID parameter that defines to which room the segment belongs. If two adjacent rooms receive the same room ID, they automatically belong to one room and no additional parameterization is required. This way, the owner can create new room situations with minimal effort.
Room Operation and Sensors
With the LROC-40x room controllers, LOYTEC offers a solution that even meets the highest standards, yet it provides a simple and uniform installation with all possible interfaces. The controllers can be complemented with LOYTEC products for room operation and sensor technology to provide a comprehensive system solution. The well-established L-VIS touch panels allow the creation of arbitrary touch interfaces for room operation. The new glass optics and high resolution fulfill highest design requirements. L-STUDIO provides ready-made graphical projects for integration to create L-VIS projects for every room segment in no time.
With L-STAT, LOYTEC provides a room operation unit that comes with integrated display, temperature sensor, humidity sensor, and CO2 sensor, NFC interface, eight capacitive touch buttons, and four physical inputs. Despite the impressive range of functions, L-STAT presents a cost-effective solution for room operation. In addition, the color of the housing, the surface, and the control symbols of the eight touch buttons can be customized on request.
For operating a room energy efficiently, LOYTEC provides with the LDALI-MS2 a multi-sensor for automatic presence detection and light measurement as reference for constant light control. The multi-sensor can be integrated seamlessly into the overall solution via the DALI bus. This has the advantage that the sensor can be directly connected to the DALI line, eliminating the need for additional cables.
