Electrical – 3 way dimmer in 4 way circuit

dimmer-switchelectricalswitch

I have a Legrand (Pass & Seymour H703P) dimmer that I installed in a 4 way circuit. This dimmer has its common connected to the line so it's 1st in the circuit line and not in the middle or end. This dimmer also has a green indicator light that goes ON when the lights are off and goes OFF when the lights are on.

Why does the indicator light on the switch only go dim when the lights are on as opposed to going completely off? The other 2 toggle switches work perfectly as does the dimmer itself in the grand scheme of things but just the green indicator on the dimmer has me concerned with only going dim when on and not completely off.

I have this same dimmer on another circuit but it's a 3 way circuit and it works like it should with the indicator light off when the lights are on. Is this because it's on a 4 way circuit and that it is expected to be dim when on?

Thanks in advance.

3/4 way switch systems have a 3-way on each end and 4-ways in the middle. As long as the smart switch is on a end (a 3-way position), it cannot possibly know there are 4-ways involved. So a simple mechanical 4-way inline is not a factor and can be disregarded.

When using dimmers, motion sensors, lighted switch, or any sort of powered switch, those absolutely do not support LEDs ... unless they do. And when they do, there are conditions and rules. So when chasing this kind of problem, it's best to divide and conquer: go back to incandescents until the problem is sorted out, then handle the "making LEDs work here" problem.
