Before replacing a Tegui or BTicino monitor, check the existing installation. A similar appearance or having two wires does not establish compatibility.
1. Identify the original device
Note the exact model number of the monitor and entrance panel and, if known, the power supply. Check the system documentation. Avoid disassembling equipment or touching the wiring if you are not a qualified installer.
2. Check which technology it uses
A conventional installation, an older digital system, and a 2-wire SCS BUS system have different requirements. The number of visible wires is only a clue: on its own, it does not identify the technology.
See our guide to identifying the system.
3. Compare monitors only after checking compatibility
The Tegui Serie 8 374494, BTicino Classe 100X16E 344786, and Classe 300EOS 344884 model numbers belong to different product families with different features. They should not be considered direct substitutes without checking the system version, entrance panel, power supply, and manufacturer limitations.
For a comparison of features and options, see Tegui monitors: differences between basic features, WiFi, and connectivity. Prices and availability should be checked on the current product pages.
4. Check which features you need
- Audio or audio and video.
- Hands-free or handset communication.
- Mobile connection through an app compatible with the exact model number.
- Opening one or more doors and the accessories required.
Frequently asked questions

No. Check the model, manufacturer, and technology.
Does a WiFi monitor work with any Tegui entrance panel?
This cannot be guaranteed without checking documented compatibility.
Which model number do I need to buy?
At a minimum, the model of the device you want to replace; if compatibility is not clear-cut, also identify the entrance panel and power supply.
