If you’re looking for equivalents for older Tegui monitors, the first step is to identify the exact reference and the installation technology. Names such as VT8, Europa Series, or Series 7 are not enough to recommend a current monitor as a direct replacement.
Important notice: this guide does not confirm a direct replacement of the VT8, Europa Series, or Series 7 with a Series 8 or a Classe 100X16E. The general equivalences previously shown in this article have been removed because they were not supported here by documentation applicable to each reference and installation.
Direct replacement and upgrade are not the same
- Direct replacement: requires documented compatibility between the old reference and the replacement for the installed system, while meeting the specified mounting, connection, power supply, and configuration requirements.
- Replacement with modifications: may require a bracket, accessories, power supply, or configuration changes expressly specified by the manufacturer. It should not be presented as a simple monitor swap.
- System upgrade: may allow current equipment to be installed by changing the panel, power supply, or other components. The fact that an upgrade is possible does not prove that the new monitor is equivalent to the old one.
Reusing cables also does not mean retaining the system technology. A project may reuse part of the wiring and still require new equipment at both ends.
Review table by old designation
| Designation | What needs to be verified | Conclusion of this guide |
|---|---|---|
| VT8 | Reference and version of the monitor, base or connector, panel, power supply, and system diagram. | No direct equivalence with Series 8, 374494, Classe 100X16E, or 344786 is confirmed here. VT8 should not be confused with Series 8. |
| Europa Series | Specific reference and the installation’s actual technology, not just the product range name. | No single current replacement is specified for the entire series. |
| Series 7 | Reference, system, panel, and connection and configuration documentation. | It is not considered compatible as a whole with current 2-wire monitors. |
| “300 Series” | Exact identification of the equipment referred to by that designation and the relevant documentation. | The name does not establish that a currently available, directly compatible replacement exists or confirm availability. |
If an equivalence is not confirmed in this article, that does not mean no solution exists. It means you should not choose or connect a replacement based solely on this table or a similar-sounding name.
Identify the technology before buying
Tegui documentation distinguishes between conventional, Teguibus, and 2-wire systems. They should not be treated as interchangeable. The system should not be inferred solely by counting the visible wires.
A 2-Wire BUS monitor is not a universal replacement for an old analog or Teguibus unit. BTicino’s technical guide limits the use of Classe 100X and Classe 300EOS to its 2-wire technology, subject to the conditions and restrictions in the corresponding diagram.
Tegui and BTicino are distinct brands. Any relationship between their products or potential compatibility must be supported by documentation for the part numbers involved, not by a general equivalence between brands.
What information the installer needs
- Old monitor: full part number and version, if stated in the documentation or on a label accessible without dismantling.
- Mounting base and connection: part number for the bracket or base and the applicable diagram, which the professional must check if dismantling is necessary.
- Entrance panel and power supply: part numbers for the equipment actually installed.
- Technology and layout: system, distributors or interfaces, number of monitors, and installation structure.
- Scope: replacement in one home or renovation of a single-family or shared installation.
- Proposed replacement: exact part number, documentation supporting its use, and any additional requirements.
Users do not need to take measurements or dismantle equipment. If information is missing, the maintenance installer must identify it before recommending a purchase.
Special attention to the VT8: do not improvise the connector
This guide does not provide a verified pinout for the VT8. Do not assign functions to its pins based on wire colors, similarity to another monitor, or connections from a different base.
A usable diagram must match the model and version and clearly identify the connector’s orientation and pin numbering. Without this information, do not make experimental connections or apply power to test.
The VT8 designation does not prove compatibility with a monitor called Series 8, or with a current 2-wire monitor.
Power, configuration, and wiring
Before installing a replacement, the installer must check that equipment’s power and configuration requirements. Do not copy configurators or jumpers from another model without verifying their function.
The inspection includes the power supply, loads, any additional local power sources, wiring, and topology limitations. Voltage requirements and measurement points must be obtained from the documentation for the specific system; there is no generic electrical test that is valid for all old monitors.
Do not bridge terminals, move configurators at random, or power connectors by trial and error. Measurements and work must be carried out by a qualified professional.
Can I take the opportunity to add Wi-Fi?
A compatible solution may be possible, but Wi-Fi does not make a monitor compatible with any old system. First, confirm the technology and scope of the upgrade; then choose the connected features.
The quote must clearly itemize the monitor cost and any potential changes to the power supply, entrance panel, accessories, wiring, or shared equipment. Don’t promise remote door release or a “no-construction” replacement without assessing the installation and chosen model.
Checks after replacing a monitor
The installer must check that calls reach the correct home, the audible alert works, there’s an image, two-way communication works, and the door lock can be released. They must also check any additional planned functions and, if applicable, the connection to the relevant app.
The monitor turning on doesn’t prove it’s compatible or that all its functions are configured correctly. In shared residential installations, the work must be coordinated with the maintenance manager and must not affect other homes.
Frequently asked questions
Can I replace a VT8 with a Series 8?
Don’t assume so just because the name looks similar. This guide does not confirm that it’s a direct replacement: the reference, technology, and applicable documentation are needed.
Can a Classe 100X16E replace any old Tegui monitor?
It’s not a universal replacement. Verify the system, reference, and requirements for the new monitor before buying it.
Are two devices compatible if they both use two wires?
You can’t reach that conclusion just by counting wires. You need to identify the technology and check the manufacturer’s compatibility requirements.
Does the whole community need to upgrade?
You can’t decide based on the monitor’s name alone. The solution may be specific to an individual unit or require a more extensive upgrade; the installer must determine this using the system details.
Does the absence of a confirmed equivalent mean there’s no replacement?
No. This article neither confirms nor rules out the availability of replacements for a specific reference. It explains what needs to be verified before recommending a replacement.
How to choose safely
Exact reference → identified technology → documented compatibility → installation and power requirements → functional test. This is the right order for evaluating a replacement. Don’t buy a monitor just because it’s advertised as “equivalent,” shares the same brand, or looks like the old one.
Reference documentation
- Tegui: separate documentation for 2-wire, Teguibus, and conventional systems.
- BTicino: 2-wire system technical guide.
These sources provide a technical framework, not an equivalence chart for the VT8, Europa Series, or Series 7. The documentation for the references involved is needed to approve a specific replacement.
