Title: Great Products - Easy to install
Review: You need a Neutral wire (WHITE) for this model. The instructions are easy to read and the product is well made. The readout is quite clear even in dim lighting. My installation went like this: Leave power on, remove old switch cover and loosen the screws on the existing switch. Use a multimeter to test which of the BLACK wires is hot (called the line) and which one goes to the light (that is called the load). You will also need to identify the neutral. To do this connect one terminal of the multimeter to the WHITE/Neutral wire and the other to a ground; You should only register a few volts (<20Va). Then disconnect the power by throwing the circuit breaker. Test the wires again; they all should show 0-Vac. Connect the wires up: Black(Line/HOT)-Black(Switch), Black(Load/Light)-Blue(Switch, and White(Neutral)-White(Switch). Turn the break back on and test! WORKS Great!
