I have attempted to install a PD-5NE dimmer switch in both a 2 way circuit and a 3 way circuit.
After connecting to either 2 way or 3 way circuit the Top and 3rd down LED's flash.
The on and off buttons will not turn on any connected lights. All lights remain turned off.
I was able to connect it to the Lutron smart bridge without issues.

I cannot find any information on what the flashing LED's mean.
Do I need to reset the switch to factory default?
