Understand the symbols of your radiator: what do the sun, the moon, and the snowflake really mean?

Understanding the symbols on your radiator transcends simple daily usage. These icons, such as the sun, the moon, and the snowflake, govern the thermal comfort of a home. The “comfort” mode ensures optimal heat, while the “economical” mode preserves resources. Adopting these settings requires particular vigilance to avoid energy overconsumption. Grasping these symbols is not just a matter of technology, but rather a strategy to maximize well-being indoors.

Symbols and Their Meaning

Modern radiators display various pictograms on their interface, each with a specific meaning. The most common symbols include the sun, the moon, and the snowflake. Each of these pictograms indicates a specific operating mode, thus allowing for the optimization of your heating management. Understanding these symbols is essential to ensure efficient and economical use of your equipment.

The Sun Symbol: Comfort Mode

The sun pictogram on your radiator indicates the “comfort” mode. This mode sets an ideal temperature, often adjusted between 20 and 22 °C, depending on the area to be heated. Sometimes, the most advanced radiators automatically adjust this temperature to adapt to the actual needs of the space. By activating this mode, your interior benefits from pleasant warmth, conducive to well-being.

The Moon Symbol: Economical Mode

The moon on your radiator represents the “economical” mode. This setting reduces the temperature by 3 to 4 °C compared to the comfort mode. A wise choice for periods of inactivity in the home. Users can predefine this temperature for the night or times of absence, thus optimizing energy consumption while maintaining an acceptable level of comfort.

The Snowflake: Frost Protection

The snowflake indicates the “frost protection” mode, encouraging a minimum temperature of 7 °C. This setting is particularly relevant for second homes or houses left unoccupied for long periods. Using this mode prevents pipe freezing, thus protecting your heating system from potential damage caused by low temperatures. Adopting the frost protection mode ensures the safety of your installation while reducing energy consumption.

Automatic Pictogram: Smart Adjustment

Some radiators integrate an automatic function represented by a clock symbol. This setting allows you to program heating according to the time of day, thereby optimizing your comfort. The system alternates between comfort mode during the day and economical mode at night. By utilizing such automation, you benefit from intelligent management of your energy consumption.

What does the snowflake mean on my radiator thermostat?
The snowflake indicates the “frost protection” mode, which maintains a minimum temperature of 7 °C in your home to prevent the pipes from freezing in winter, especially useful if you are away for an extended period.
How does the Auto mode work on my radiator?
The Auto mode combines the settings of the sun and the moon, allowing your radiator to automatically adjust the temperature according to predefined schedules, ensuring optimal comfort while saving energy.
Is it important to understand these symbols to save energy?
Yes, understanding these symbols is crucial to optimizing the use of your heating. By properly using the comfort, eco, and frost protection modes, you can significantly reduce your energy consumption and bills.
Can I program my radiator using these symbols?
Yes, on certain radiators equipped with programmers, you can set schedules for switching between comfort mode and economical mode according to your daily needs.
What should I do if my radiator does not respond to the symbols?
If your radiator does not seem to respond to the symbol settings, there may be a technical issue. It is recommended to check the system or consult a professional for a diagnosis.
