1. Power off the break
2. Find Neutral Wires at the live side.
The master switch must be installed at the live side in the 3-way circuit. (Find correct wires)
Make sure there are neutral wires for the master switch. If not, the switches cannot work properly.
Neutral wires are white and NOT used by your old switch. You can send us photos of the wires at both
3-way switch locations for assistance.

Figure 2 - Wiring Diagram for 3-Way
Tips:
Wires on your old switches are:
1st Switch: Live, TRA1, TRA2
2nd Switch: Load, TRA1, TRA2
TRA-1 & TRA-2 is very easy to identify. Generally 1red, 1black. They come from the same location and
both connect to the old switch.
Neutral wires are not used by your old switch.
Recommended Connection procedures
1. Master Switch
1.1. Connect Ground Wire (Copper or Green. This is not necessary)
1.2. Connect Neutral Wire (White, not on old switch. This is necessary for wifi switch)
1.3. Connect Live Wire (Black, hot wire on old switch)
1.4. Turn on the breaker, and the indicator on the switch will light up. If not, send us a photo of the wiring
1.5. Turn of the breaker
1.6. Connect TRA-1 & TRA-2
2. Add-on Switch (Mater Switch must connect well first)
2.1. Connect TRA-1 with Red wires in the Wall
2.2. Connect TRA-2 and Load Wire with Black wire from the wall (3 of them together)
2.3. Turn on the breaker; both Master and Add-on Switch can manually turn on/off dim the light bulb.

4. FQA:
1. How can I know it is connected correctly?
A: Press the on/off button, dim button on both Master and Add-On switch. They should work properly.
Indicator lights on the Master Switch can show the brightness of light bulbs.
2. After installing the Add-On switch, I see all indicator lights flash on the Mater Switch. What’s wrong?
A: This means the TRA-1 and TRA-2 are reversed. Just check and change them back.
3. I cannot find the neutral wire in both outlet boxes; Can I still use this 3-way dimmer switch?
A: No, the neutral wire is necessary for the Master Switch.
Although your old switches do not need a neutral wire. There are spare white neutral wires in the outlet
box. Please send us photos of the wires inside the outlet boxes.
4. How can I find which one is the live (hot) line, neutral wire?
A: Besides the ground wire, there are three wires on your old switch in general:
1 black & 1 red wire from the same location, they are TRA-1 & TRA-2;
1 black wire from another location, it is live or load. You can use a tester to test it.
If it is live (hot) wire, install Master Switch here;
If it is load wire, install Add-on Switch here.
