Welcome. My name is XXXXX XXXXX would be glad to assist.
Reading over the installation manuals for the 3106 and the wall stations,
they communicate with each other and do not wire like standard wall switches.
The main unit gets the wires connected that go to the different locations.
Then it is basically the master and the wall stations are slaves.
You can add 3 wall stations per unit(3106), and you run 4 wires, 2- twisted paired cables from the main unit to
the first wall station. Then from the first wall station to the second, from the second to
the third (if you want that many).
Any wall station along with the main unit can control any set of lights, so they are all
their own switches so to speak.
You program the wall stations to communicate with the main unit similar to a ceiling fan
That way at any wall station, you can turn on the lights, or off since they all tell the main unit
what to do, then the main unit (3106) controls the lights accordingly.
As for wall stations, you decide how many scene functions you want at the wall stations and purchase the appropriate one.
If you are going to program only four different setups, then maybe a 5 scene wall station would suffice.
That will be up to you to decide how far you will go with setting up the different light situations.
Each terminal can accept 2 #18 AWG
Maximum of 1000 ft. (300 m) between the
GRAFIK Eye control
unit and the third wall station
Hopefully that clears up the items in question.
