C-BUS EDLT compared?

Looking at the catalogue there are 2 x different espresso black EDLT.

But I really cannot see them difference in them?

5085EDLB-EB
C-Bus enhanced DLT, Saturn wall switch. Black grid, Espresso Black glass fascia, black buttons.

5085EDLW-EB
C-Bus enhanced DLT, Saturn wall switch. White grid, Espresso Black glass fascia, black buttons.

Images of both look identical?

I know you can programme the back ground colours of the LED screen so why are these Two models listed?

EG:

1 When you set it to "white background" I assume it will give it a black grid.

2: When you set it to "black background" I assume it will give it a white grid.

So why bother buying one or the other catalogue numbers if the change in colour is made by programming..

Am I missing something? is there an actual a black grid / white grid that is set by factory and can not be changed by programming?

Can someone please point out exactly what is the difference?

Many thanks.

 

The colour refers to the colour of the back grid plate. The back plate on the image below is white, it can also be black like on the zen switch.

 

Perfect that’s cleared that up. Many thanks.
