I want to replace the existing 3-way switches with the wireless dimmer PD-6WCL and PICO remote control. The existing switch in Location 1 has actually 5 wires in this apartment unit, I have identified the 2 travel wires (red and blue), I identified the Line/Tag wire(orange) that is connected to a black terminal screw.The other 2 wires, (one orange one yellow ) not quite sure what they are. Oh, there is also another bare ground wire. I connected a black wire from the dimmer switch to the 2 travel wires, and the other black wire to all 3 wires (orange orange yellow), ground to ground.When I switch back the power, the lights are on,but the led light on the dimmer is not on. The dimmer doesn’t respond when I press the buttons. The lights are still on and no way to switch them off.I installed the PICO remote in Location 2 as instructed.Can anyone help to point out the problem as to why the dimmer is not working? Or is it that the dimmer is fault?Thanks
