The provided information describes wiring a Lightwave dimmer switch in a two-way system (where a light is controlled from two locations). Here's how to approach it, based on that information:
Understanding Two-Way Switching & Lightwave Dimmers
Traditional two-way switching uses two "two-way" switches, also known as "three-way" switches in North America, that redirect the power flow to either complete or break the circuit to the light. A Lightwave dimmer adds a smart home element, but the fundamental wiring principle is adapted, not replaced. The "C", "L1", "L2" terminology refers to connections on a traditional two-way switch, which need to be rewired to the Lightwave dimmer.
Wiring Instructions for Lightwave Dimmer in a Two-Way System
Here's the process for adapting the wiring to use the Lightwave dimmer:
-
Identify Existing Wiring: At both switch locations (the one where you're installing the Lightwave dimmer and the one that will remain a standard two-way switch), carefully note which wires are connected to the following terminals on the existing switches:
- C (Common)
- L1 (Line 1)
- L2 (Line 2)
Important: Before starting any electrical work, turn off the power at the circuit breaker! Use a voltage tester to confirm the power is off.
-
Wiring the Lightwave Dimmer: At the location where you're installing the Lightwave dimmer:
- Move all wires that were connected to the L1 terminal on the old switch to the L terminal on the Lightwave switch.
- Move all wires that were connected to the L2 terminal on the old switch to the X terminal on the Lightwave switch.
- Wires that were connected to the C terminal are not used on the Lightwave dimmer. Safely terminate these wires individually with wire connectors (e.g., Wago connectors or wire nuts) inside the electrical box. You can also remove them completely if you're certain they are no longer needed for other parts of the circuit. Important: Label the wires clearly before disconnecting them.
-
Wiring the Remaining Two-Way Switch: The other switch in the two-way circuit will remain a standard two-way switch (three-way in North America). You will likely not need to change the wiring at this switch. The Lightwave dimmer handles the switching logic through its "X" terminal connection to this switch. However, double-check that the common wire (typically the one with the power coming in or going out to the light) is connected to the "C" terminal on this switch.
-
Testing: After wiring both switches, carefully restore power at the circuit breaker and test the functionality of the two-way switching. The light should turn on and off correctly from both switch locations, and the Lightwave dimmer should control the light level.
Important Considerations:
- Neutral Wire: The provided instructions do not explicitly mention the neutral wire. Most smart dimmers require a neutral wire connection. Ensure your Lightwave dimmer is properly connected to the neutral wire according to its specific instructions. The absence of neutral wiring can cause issues with the dimmer functioning correctly.
- Grounding: Always ensure that the ground wire (typically bare copper or green) is properly connected to both switches and any metal boxes.
- Safety: If you are not comfortable working with electrical wiring, hire a qualified electrician. Incorrect wiring can be dangerous and could create a fire hazard.
- Lightwave Specific Instructions: These are general guidelines based on the provided information. Refer to the specific installation instructions that came with your Lightwave dimmer for detailed wiring diagrams and safety information. The instructions may vary slightly depending on the Lightwave model.
- Voltage: Ensure that both switches are rated for the voltage and wattage of the circuit.
