The LCN-GVShome system serves as a central control unit for private buildings. The maintenance-free LCN-GVShome PC already has pre-installed LCN-GVS visualization software. The building can be controlled and visualized using a web browser or app. The necessary Windows software license is also included. In addition to the standard functions for building control, the visualization system for controlling and managing a building also includes timer functions, central access control with person registration and an event detector (including logical links, also with time & date), which can also send messages by email, SMS, etc. The connection to the LCN bus is established via the LCN-PKU coupler. The PC can be connected via LAN (RJ45) using a router. Visualization, monitoring and control of large properties distributed worldwide Visualization of small properties Control and monitoring of the energy efficiency of buildings and properties with data recorders Access control with person registration for all buildings with central and decentralized administration of authorizations Automatic monitoring of events according to any criteria. The event detector not only alerts, but also intervenes itself. The included license enables the control/visualization of 20 LCN modules. If more modules are installed in the building, the number can be increased with an extension license. This also applies to the other licensed options, such as the timer functions. The LCN bus connection is made either directly via LCN-PKU or via an LCN-PCHK connection. This has the advantage that the LCN-PRO can access the bus in parallel with the LCN-GVS. The LCN bus connection must be set up before a tableau can be set up. To create a tableau in the LCN-GVS you need a current LCN-PRO project file.
