Do you have a Tegui Serie 8 374494 and want to replace it with a BTicino Classe 100X16E 344786 with WiFi to answer calls from your mobile? It is a replacement worth investigating, but it should not be considered resolved solely because both monitors are 2-wire.
The official documentation identifies the 374494 as a 2-wire monitor with a handset and the 344786 as a connected 2-wire hands-free monitor. This similarity makes it possible to consider the upgrade; confirmation for a specific home requires checking the installation, power supply, and existing functions.
Quick answer: can I replace the 374494 with the 344786?
The 344786 is an option that may be considered for upgrading an installation with a 374494, subject to technical verification. The product sheets consulted describe the characteristics of both devices, but do not by themselves constitute a direct replacement chart that guarantees the result in every installation.
Before purchasing, the installer must identify the system and check the applicable wiring diagram for the new monitor. No universal equivalence or instruction to connect the wires in apparently identical positions is provided here.
What changes between the two monitors
Tegui Serie 8 374494: handset conversation
Legrand’s official product sheet describes the 374494 as a 2-wire video door entry monitor for surface installation, with a handset and a 4.3-inch color screen. It includes buttons for opening the lock, automatically activating the entrance panel, and a configurable auxiliary function.
BTicino Classe 100X16E 344786: hands-free and WiFi
The official catalog describes the 344786 as a connected 2-wire/WiFi monitor, hands-free, with a 5-inch color screen. The change does not merely involve adding mobile connectivity: it also changes how the conversation is handled and how the controls are arranged.
The current documentation consulted covers the Home + Security application for managing functions such as receiving calls, opening, and activating the entrance panel, depending on the system configuration. For commissioning, always use the documentation corresponding to the supplied version.
1. Confirm the installed system
The professional must identify the existing monitor and the components serving it: entrance panel, power supply, and distribution. The generic mention of “2 wires” does not make all systems on the market interchangeable.
If the reference of the installed device does not match 374494 or the installation has been modified, that specific case must be reviewed. These guidelines must not be applied to 4+N analog systems or other architectures.
2. Review the power supply and sizing
It cannot be guaranteed that the current power supply is sufficient or that it needs to be replaced without identifying it and checking the manufacturer’s wiring diagram. The installer must review the existing load and the new monitor’s requirements, especially if there are several indoor stations in the home.
An additional power supply should not be purchased routinely, nor should its need be ruled out without verification. In a community installation, the user must not disconnect or modify shared elements either.
3. Retain the call and the necessary functions
Before removing the old device, it is advisable to document its configuration and note which functions are used. The professional must transfer the applicable functions by following the instructions for the new model, not by copying jumper positions without checking their meaning.
- Call to the correct home.
- Audio and video during communication.
- Opening of the corresponding door.
- Automatic activation of the outdoor panel.
- Auxiliary functions that are enabled.
- Operation with other monitors in the same home, if any.
The line termination and primary/secondary configuration must also be checked when applicable to the setup. Configurator positions are not included because they depend on the equipment and the actual installation.
4. Check the access points if there is more than one door
If you currently receive calls from several entrance panels or open more than one door, each function must be checked independently. The fact that one opening works from the old monitor does not guarantee that it will be automatically reproduced on all the controls of the new device or in the app.
The final test must be performed from each access point, verifying which door is activated in each situation.
5. Prepare the connection to the mobile phone
WiFi connects the monitor to the home network for connected functions; by itself, it does not turn the entire community installation into an IP system or replace the building’s BUS.
After completing and testing the local installation, follow the app pairing process specified for the monitor version. Check the device’s connection to the network and the notification and usage permissions required on the phone.
Do not share passwords or pairing codes publicly. If setup does not progress, review the instructions for that version before resetting the device.
Can the existing wiring be reused?
This is something the installer must check. Replacing a 2-wire unit can be considered using compatible infrastructure, but the consulted datasheets do not allow us to promise that every existing cable, route, or branch will be valid without inspection.
The condition of the wiring, topology, and distances must be checked against the system documentation. The new monitor's physical mounting must also be checked: it should not be assumed that the existing bracket is reusable or that the mounting points match.
Tests before considering the replacement complete
- Receive a call from each entrance panel serving the home.
- Check the image and two-way audio.
- Verify each planned door release and auxiliary function.
- Test the other internal units, if any.
- Pair the mobile device and check the enabled remote functions.
A successful test from the monitor does not replace checking the app, and correctly pairing it with the mobile device does not certify all local functions either.
Frequently asked questions
Is it a direct replacement, simply removing one and installing the other?
It should not be stated that way without reviewing the specific case. Both are documented as 2-wire devices, but the installation, power supply, mounting, and configuration must be verified.
Do I have to change the entrance panel?
This cannot be decided solely from the references of the two monitors. Whether elements need to be retained or modified depends on the compatibility of the complete system and must be confirmed by the installer.
Which app does the 344786 use?
The current documentation consulted covers Home + Security. The manual for the supplied version must be followed rather than choosing an app based on an old tutorial or the generic name of the family.
Are the Tegui 374494 and BTicino 344786 the same product?
No. They are different references and brands. This examines a possible upgrade between devices, not whether the products are identical.

In summary: the BTicino 344786 allows for an upgrade with connected features compared with the Tegui 374494 with handset. To confirm the replacement in your home, the installer must validate the system, power supply, and all the features you need to retain before carrying out the change.
