Direct Answer: C-Bus Ethernet Interface (5500CN) — Stuck-On Channels

Stuck-on channels are typically caused by fused load contactors inside the relay. When inrush currents exceed the relay rating, the contacts weld together, keeping the lights permanently on.

Step-by-Step Diagnostic Steps

Attempt to manually toggle the channel override button on the unit.
If the button is physically stuck or does not change the light state, the relay is fused.
Turn off the circuit breaker for the affected lights to save energy.
The internal relays cannot be safely un-welded.
A hardware replacement of the dimmer or relay module is required.
