Gira L1 REG features: Logic functions: Functional diversity thanks to a block library with 36 logic blocks (e.g. basic mathematical functions, sun-position-controlled roller shutter and blind control, temperature control, partition wall control, staircase lighting, random generator). Configurable logic blocks (e.g. freely selectable number of inputs). Simple 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 one project (300 KNX group address data points, 180 freely available device data points). Intercom function to exchange values e.g. between another L1 or an X1 via Ethernet. Optimized commissioning: quick project changes or updates possible during operation without restarting the device. Two RJ45 sockets with switch function support easy looping of the patch cable.
