It depends on how the original three way switches where wired.
If the line was in one box and the load in the other. It would be wired different than having both the line and load in one switch box and the slave switch and travelers in the other.
The WS14A to the WS13A needs two wires. Line and Switch if you go by the labels in the instruction sheets.
Depending on where the line and load are in your setup. Three wires possible could be needed between them.
Can you give us some information on how the original switches where wired?
I just tracked the original switches where wired.
- The first box where I installed the ws14a has three wire, red, black, and white. Red wire is the load. The white and the black wires connect to the second box where I installed the ws13a. There is no common wire in the first box.
- The second box has live and common wire where I installed the ws13a with live, common, and the black and white wires from the first box are connected.
This is wrong because the ws13a must be install in the first box since it has the load wire. However, no common wire in this box.
So as my understanding, the fist box is the master. However, I could not install the ws13a to the first box because it has no common wire.
I installed the ws13a to the second box where I can connect live and common. My ws14a does not function.
In this case, how can I use x10 ws13a/ws14a?
First box (first picture) and second box (second picture) are attached
Thank you
