With LCN, practically all functions of a building can be automated. The flexibly expandable LCN system makes it possible to link manual commands with automatic functions. In this way, a property can not only be controlled and regulated across all trades, but also offers the user – almost incidentally – maximum individual comfort and financial savings thanks to energy-efficient consumption optimization.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

An extra line network is not required for the LCN bus. The data wire is treated as a mains wire and may therefore be routed together with the 230 V installation in accordance with VDE. The LCN modules do not require additional power supplies. They are connected directly to the laid mains voltage cable.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tPlanning LCN installations is particularly easy because LCN imposes very few regulations: the only thing to consider is the maximum number of modules in the lowest level, namely 250. For large installations, a maximum of 250 modules each form a segment. Up to 120 such segments can be directly coupled for 30,000 modules in maximum expansion. However, rarely more than 250 modules and thus several segments are necessary. Because, depending on the requirements of the building owner, 100 to 500 rooms can be controlled with only 250 modules.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In order for each LCN module to be addressable, it needs an address. This is a number between 5 and 254, and is assigned by LCN-PRO. A data telegram can be sent to this address from any point in the overall bus. If several stations are to be addressed with one telegram, this is done via group addressing. Per LCN bus segment, 250 group numbers in the range of 5 to 254 can be freely assigned. The number of members per group is unlimited. Each module can be a member of up to 12 groups. In the LCN system, groups are only formed if several consumers are actually to be addressed simultaneously. With a point-to-point transmission, on the other hand, addressing is direct (“to module 55: GF WC light”), as one would intuitively expect.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The temperature within a room should be manually preselected and automatically maintained only when the room is in use. When the window is open, the radiator must be switched off automatically and after closing the window it must heat up again to the preselected room temperature. If no one is in the room for a longer period of time, the temperature should be automatically lowered to a low maintenance value.<\/p>\n

All functions must also be manually accessible. For the implementation, only a decentrally installed bus module is required (here: UPP), to which all sensors, the actuator for the heating valve and the pushbuttons required for manual operation are connected. Various temperatures can be preselected via the LCN sensor keypad. The current room temperature is then shown on the display or in the form of a bar graph. Alternatively, EIB\/KNX, EnOcean or conventional pushbuttons can be used for operation.<\/p><\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

A transponder system is to be used to unlock a door and thus grant access to the building. The door area is automatically illuminated by presence detectors when approached. To enable protection against misuse of the open door, a door contact is installed. If the door remains open for a certain period of time, a security service can be informed, for example, by help of the LCN-GVS visualization system. The LCN transponder systems enable the use of LCN transponders and\/or transponders from various manufacturers, including car keys.<\/p>\n

The LCN-GVS can be used to remotely control the entire LCN system using browser-enabled operating devices (smartphones, tablet PC, notebook, etc.), for example, to control and monitor the entrance door in this case. In addition, the LCN-GVS system offers the possibility of sending SMS messages via the Internet or using a GSM modem via the LCN-GVS system. When using the LCN-GVS APP, any number of employees receive important information as a push message directly to their smartphone.
