Trying to install Luther on CL dimmer switch.
The wiring on my existing switch has two black wires connected to one screw, and a red wire connected to another screw, as well as a ground wire connected to a screw in the box.
The installation video says to Cap off the red and white wire on the new dimmer switch.
That’s would leave one one of the existing back wires unconnected. Should I cap this wire off or do I connect it somewhere?
