05. Controller Assignment

NOTE: For installations where an LR7 is being installed with a Neo Wall Control, C-1 will always need to be assigned to the Neo Wall Control.

Upon initial start-up, all connected LR7 controls (up to 3) will display C-0. After 3 seconds, an auto-assignment process occurs, displaying C-1, C-2, and C-3. The user can change assignments between C-1 and C-3 using the [UP] or [DOWN] buttons. A C-1 controller is required for the system to function correctly, with each controller needing a unique assignment. The displayed text remains until the user presses the [PROG] button to enter the Home Screen. Subsequent power cycles will show controller IDs for 3 seconds before proceeding to the Home Screen.
