Gira L1 REG Features: Logic functions: A variety of functions through a library of 36 logic modules (e.g., basic mathematical functions, sun position-controlled roller shutter and blind control, temperature regulation, partition control, stairwell lighting, random generator). Configurable logic modules (e.g., freely selectable number of inputs). Easy parameterization of timers and scenes: up to 20 timers with 10 switching times each, up to 20 scene sets with 64 scenes each. Up to 480 data points can be used in a project (300 KNX group address data points, 180 freely available device data points). Intercom function to exchange values, for example, between another L1 or an X1 via Ethernet. Optimized commissioning: quick project changes or updates during operation without device restart possible. Two RJ45 sockets with switch functionality support easy daisy-chaining of the patch cable. High security: The encrypted TLS data transmission between GPA and Gira L1 prevents eavesdropping by third parties. The device password protects the Gira L1 from unauthorized access. Project backup: Save a project copy on the Gira L1. Commissioning: Physical address and application are parameterized with the KNX commissioning software ETS from version 4.1.8. Further project planning is done via the Gira Project Assistant (GPA). The Gira Project Assistant is available for free in the Gira download area. Functional extensions or updates via firmware and software updates. Hardware prepared for KNX Secure. Future firmware update required. Notes: Powered by external DC 24 V.
