When it comes to thermal comfort in homes or workplaces, people often refer to room temperature. However, what truly influences our sense of well-being is the so-called perceived temperature.

But what’s the difference?

Room Temperature vs. Perceived Temperature: not the same thing

Room temperature is an objective measurement taken by thermometers—it simply indicates the amount of heat present in a space. Yet anyone who has felt uncomfortably hot and sticky at 27°C in summer, or chilly at 21°C in winter despite the thermostat reading, knows that it doesn’t always match how we actually feel.

This is where perceived temperature comes in. It factors in additional key elements, such as humidity and air movement. For example:

  • High humidity in summer slows down the evaporation of sweat, making us feel hotter.
  • In winter, air that is too dry can make us feel colder, even if the room temperature is adequate.

In short, perceived temperature is the real thermal sensation we experience, shaped by a mix of environmental and physiological conditions.

Beyond degrees: how the C900 programmable thermostat regulates perceived comfort

Always at the forefront of climate control, Fantini Cosmi has taken the concept of comfort to the next level with the launch of the intelligent C900 programmable thermostat.

The C900 doesn’t just measure room temperature. Thanks to its advanced sensors, it also monitors humidity levels in real time—an essential factor in determining perceived temperature.

How the C900 works: data, AI, and personalized comfort

The WiFi-enabled C900 programmable thermostat:

  • Continuously analyzes temperature and humidity
  • Calculates perceived temperature using real data
  • Optimizes heating and cooling activation, anticipating or delaying system start-up based on user habits
  • Uses geolocation to adapt thermal comfort as you approach or leave home
  • Learns from past behavior to provide increasingly precise and efficient scenarios

The result? Perfectly calibrated thermal comfort tailored to people and environments, achieved with minimal energy consumption.

Real comfort, real efficiency

Understanding the difference between room temperature and perceived temperature is the first step toward more authentic and conscious well-being. With the C900 programmable thermostat, Fantini Cosmi translates this knowledge into technology, offering a solution that combines comfort, energy savings, and sustainability.

Because it’s not just about the number of degrees—it’s about how they feel!
