If you’ve made it this far, it’s very likely you are replacing a component of a Tegui or BTicino panel and have encountered a quite common doubt: What is the difference between the GF 351000 and the GF 351100? And what are the 351001 and 351101?
This is a question we frequently receive from installers, community maintainers, and distributors. At first glance, the references seem very similar, but they are not the same. It is important to know exactly what each part is before ordering a replacement.
First things first: there are two types of components
Within the Sfera New range from Tegui and BTicino, the audio module of the street panel consists of two distinct parts:
- The Audio Group (GF) : is the electronics, the active component that manages audio, calls, and door opening. It is the "brain" of the module.
- The Front or Profile (ref. x01) : is the aesthetic cover, the visible face of the module. It has no electronics. Its function is purely mechanical and aesthetic.
Therefore, the four references are grouped as follows:
| Reference | Type | Function | Indicative price |
|---|---|---|---|
| 351000 | Basic Audio Group | Audio electronics (up to 100 calls) | 129,89 € |
| 351001 | Front panel of the basic audio module | Aesthetic cover of the 351000 | 20,11 € |
| 351100 | Advanced Audio Group | Audio electronics with software configuration | 162,35 € |
| 351101 | Front panel of the advanced audio module | Aesthetic cover of the 351100 | 23,11 € |
What is the difference between the GF 351000 and the GF 351100?
Both are audio groups for the 2-wire system (BUS SCS) of the Sfera New range. Both manage audio, calls, and door opening. The difference lies in how they are configured:
- GF 351000 (basic) : is configured only through physical configurators on the board itself. Simple and straightforward, ideal for small installations or direct replacements. Capacity for up to 100 calls with buttons.
- GF 351100 (advanced) : allows physical configuration or via TiSferaDesign software from a PC. It offers greater flexibility during commissioning and facilitates maintenance in more complex installations.
Once installed, the operation is practically identical. What changes is the installer's convenience during configuration.
And what about the front panels 351001 and 351101?
The fronts are simply the aesthetic covers of each audio group. They have no electronics and do not affect the system's operation.
- 351001: front for the basic audio group 351000.
- 351101: front for the advanced audio group 351100.
They are specific to each model and are not interchangeable with each other. If you change the audio group, make sure to use the corresponding front.
Which one should I order?
It depends on the situation:
- Replacement of a faulty device: the most practical thing is to install the same model that the panel originally had. This avoids unnecessary reconfigurations.
- New installation or new project: we recommend the GF 351100 for the flexibility offered by software configuration with TiSferaDesign.
- Only the cover is damaged: in that case, you only need the front (351001 or 351101), not the complete audio group.
Frequently Asked Questions
Does the 351100 provide better audio quality than the 351000?
No. The communication quality is the same. The difference lies only in how the device is configured.
Can I replace a 351000 with a 351100?
Yes, as long as it is correctly configured for the existing installation. In that case, you will also need to change the front to the 351101.
Is the front sold separately?
Yes. The front (351001 or 351101) is sold separately from the audio group. You can order just the cover if the electronics are in good condition.
What is TiSferaDesign?
It is the BTicino/Tegui configuration software for Sfera New systems. It allows programming the 351100 audio group from a PC, copying projects between installations, and updating the firmware without dismantling the panel.
Conclusion
The four references form two pairs: 351000 + 351001 (basic audio group + its front) and 351100 + 351101 (advanced audio group + its front). The main difference between the two audio groups is the ability to configure the 351100 using TiSferaDesign software, which facilitates commissioning and maintenance in more demanding installations.
Before ordering the replacement part, identify which model your panel has installed. If in doubt, a photo of the electronics is usually enough to confirm the correct reference.
