Logic functions: A range of functions thanks to the module library with 36 logic modules (e.g. basic mathematical operations, shutters and blind control, temperature control, partition wall control, staircase lighting, random generator).
Configurable logic nodes (e.g. freely selectable number of inputs).
Easy parameterisation 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 discretionary device data points).
Intercom function for exchanging values e. g. between a further L1 or an X1 via Ethernet.
Optimised start-up: Fast project changes and updates during operation without the need to restart the device.
Two RJ45 sockets with switch functionality support simple loop-through of the patch cable.
High security: Encrypted TLS data transfer between GPA and Gira L1 prevents interception by third parties. The device password protects the Gira L1 against unauthorised access.
Project saving: Saving of a project copy on the Gira L1.
Start-up: The physical address and application are parameterised with the KNX start-up software ETS from version 4.1.8. Further configuration is performed in the Gira Project Assistant (GPA). The Gira Project Assistant is available free of charge in the Gira download area.
Functional extensions and updates via firmware and software updates.
Hardware prepared for KNX Secure. Future firmware update required.
