The new C900 Series represents a true evolutionary step in home climate management. WiFi connectivity, artificial intelligence, and advanced functions that regulate perceived temperature form the foundation of this innovative line, created for those seeking efficient, smart, and personalized thermal comfort.
Artificial Intelligence serving comfort
The technology of the C900 Series goes far beyond simple scheduling. These devices feature an advanced self-learning system capable of recognizing user habits and the thermal characteristics of the system. The algorithm learns when and how the system reaches the desired temperature, automatically adjusting on/off cycles to maximize comfort and efficiency.
This way, the system doesn’t just follow a fixed program—it anticipates or delays activation according to real user needs and behaviors.
Perceived temperature control
Another key strength of the C900 Series is its ability to regulate operation based on perceived temperature, thanks to a combination of temperature and humidity sensors. This approach makes climate management more accurate and closer to real comfort, going beyond the limits of simple ambient temperature.
Geolocation and dynamic management
Geolocation is a key feature of the C900: the programmable thermostat can automatically adjust the temperature based on the user’s distance from home. When away, the system lowers or switches off heating/cooling; on return, it restarts in advance to ensure a comfortable environment. All this happens without manual intervention, reducing unnecessary energy consumption.
“Open Window” Function and Energy Savings
Thanks to its window detection feature, the device can identify sudden drops in temperature and automatically suspend operation, preventing waste. A simple yet highly effective function to improve overall system efficiency.
Modern design and flexible Installation
The C900 Series is designed to stylishly fit into any setting, whether classic or modern. It consists of six programmable thermostats that differ in shape (square or rectangular), color (white, black, or sand), and offer two installation options: wall-mounted (battery-powered only) or flush-mounted on 500, 502, or 503 wall boxes, depending on the selected model.
The design is minimalist, featuring only three LED digits and three buttons to easily select the various functions.
The programmable thermostats can be powered by batteries or, with the dedicated C800AL auxiliary kit, via 230 V mains power.



Remote control and app management
Integration with the Intelliclima+ app (iOS and Android) allows complete remote management, from simple temperature adjustment to advanced scheduling. Only through the app can all smart functions be accessed, including:
- Perceived temperature regulation
- Energy consumption monitoring (system operating hours)
- CO₂ savings tracking
- Open window detection
Technology and sustainability
Environmental sustainability is also a priority: the C900 monitors ecological impact by calculating usage and consumption optimization statistics, displaying CO₂ savings. In the Intelliclima+ app’s infographic sections, users can monitor annual kWh savings and the reduction in CO₂ emissions, represented as an equivalent number of “trees planted.”
This allows users to make conscious, data-driven decisions for efficient energy use.
Security first
Equally important is compliance with European regulations on cybersecurity and personal data protection. The C900 chronothermostats fully comply with the RED Directive (2014/53/EU), ensuring a connected yet secure experience.
Invisible technology, tangible results
With the C900 Series, Fantini Cosmi brings smart technology into the heart of the home, transforming climate control into an automated, intelligent, and increasingly sustainable process. More than just a programmable thermostat, it is a digital assistant for thermal comfort—designed to think ahead on your behalf.
