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.
