If the shutter is fully open, the brown wire is internally disconnected. Applying phase to brown does nothing. To close, phase must be applied to black. 5. Wiring for Home Automation (Relay Module) Modern installations use a centralized controller (e.g., KNX, Zigbee, or wired automation). In this case, the 3 wires connect to two relays (one per direction). 5.1 Relay Module Wiring (e.g., 2-channel dry contact module) | Relay Module Terminal | Connected to | |----------------------|--------------| | Relay 1 Common (COM1) | Live (L) 230V | | Relay 1 NO (Normally Open) | Brown wire (motor up) | | Relay 2 Common (COM2) | Live (L) 230V | | Relay 2 NO | Black wire (motor down) | | Neutral bus | Blue wire | | Earth bus | Green/Yellow |
