Are Tegui and BTicino the same?
They don’t always have the same commercial reference or EAN, but in several Tegui and BTicino devices they correspond to the same technical model or a direct equivalence within the Legrand Group. This happens especially in the Classe 100 2-wire BUS/SCS range.
Below we explain the clearest cases so you can identify which reference you need according to your installation.
1. Classe 100V16B — Basic hands-free monitor

The references Tegui 374511 and BTicino 344652 correspond to the same technical model Classe 100V16B: hands-free monitor with 5" color screen and 2-wire BUS/SCS system.

The references 344786, 344782, and 344682 belong to the same technical family Classe 100X16E WiFi from the Legrand Group.

How to know which reference I need?
The key is the technical model, not the commercial reference. If your installation is 2-wire BUS/SCS and you need a hands-free monitor with a 5" screen, any of the equivalent references will work correctly.
