      AI-powered heating: your comfort taken to the next level

      Rointe has developed the exclusive AIH Intelligent System, an innovative layer of artificial intelligence designed specifically for our connected products. This technology analyses your installation, learns from your habits and evaluates the comfort level of your home. Thanks to this, the Rointe Nexa app can offer personalised recommendations to improve your consumption, reduce costs and optimise energy use—without you having to lift a finger. A more comfortable, efficient and truly personalised experience.

      An intelligent system ready to learn even more about you

      All data obtained by our products is transmitted securely using encryption algorithms that ensure integrity, confidentiality and anonymity. This information is essential for our AIH intelligent layer to deliver all the technological advantages that artificial intelligence can offer.

      Once your products are installed, the AIH System will evolve with you and your installation, learning from your usage habits to provide increasingly accurate recommendations and configurations through machine learning.

      Intelligent diagnosis

      The intelligent diagnostic function uses artificial intelligence (AI) to monitor and optimise your heating performance, improving energy efficiency in real time.

      View your comfort level

      Thanks to the AI integrated into your system, you can monitor your comfort level at any time from the app, with real-time data that helps you maintain a comfortable and efficient temperature.

      Personalised recommendations

      The AI-powered heating system analyses your habits and environment to offer personalised recommendations that enhance comfort and optimise energy consumption.

      New Limited Mode that helps you save

      The LIMITED MODE function, available on all Rointe connected products, allows you to set a custom temperature range, with a minimum and maximum, locked by password. In addition, it restricts access to the product menu, preventing unauthorized changes. It is an ideal feature for hotels, hostels, or tourist accommodations such as Airbnbs, as it limits excessive heating usage and helps reduce energy consumption.

      HOW DOES IT WORK?

      By default, the temperature limits for the Eco and Comfort operating modes are 7.5ºC and 30ºC, respectively.

      Thanks to Limited Mode, we can modify these limits.

      We can, for example, set 25ºC for Comfort mode and 17ºC for Eco mode, so that the user can only move between temperatures within this range.

      Limited Mode is also ideal in installations in public places such as residences or schools, allowing users to modify the temperature of the product within a selected limited range.
