    Firmware Update Guidance
    SpaceLogic C‑Bus Automation Firmware v1.19.0 is an important update:

    • Required for all installations still in the commissioning phase
    • recommended for installations already commissioned
    When upgrading from any earlier Version 1 firmware, please observe the following:

    • Power the Automation Controller using a stable 24V DC supply
    • Ensure the controller is connected to an active C‑Bus network with a functioning system clock
    • Do not interrupt power or the C‑Bus connection during the upgrade process
    Following these precautions will help ensure a reliable and successful firmware update.
