All my house is using this configuration (one couple of VMB4PD+VMB1TS by room, in same wallbox), nicely working since 2010… but the Biticino format (3 modules I suppose) seems to be incompatible with new Velbus module (especially glasses VMBxxx)
I hope my configuration would still be working for long time, but I would to know if Velbus has already a solution?
Thanks by advance
Hi @Golfy ,
Great to see that our very first digital panels are still faithfully running in your home! We actually still have them in our HQ as well – going strong after 18 years (they’ve basically earned a retirement badge by now 
).
Since those days, we’ve moved away from the old Bticino rectangle format and adopted the square design, which fits most of the flush-mounting boxes used in modern construction.
The good news: Velbus always stays backwards compatible. So you can easily replace your current setup with the newer VMBELx or VMBGPx glass panels. The less-good news: the form factor inevitably evolves with time.
In most retrofit projects, people choose to replaster the old rectangular opening so the new panels can shine in style. We’ve also seen some installers use a plastic board to cover the rectangle and mount the new glass panel on top. Technically it works… but let’s be honest, it doesn’t exactly make the wall Instagram-worthy 
.
Good luck with your upgrade – and if you do go ahead, don’t forget to share some pictures of the result. We love seeing Velbus projects get a second life!
