🧠 What is a presence sensor
👀 How presence is detected
Smart heating systems can use different technologies. Typically, heating products rely on a combination of:
- passive infrared (PIR) sensors, which detect the heat emitted by the human body;
- algorithms, meaning software-based logic, designed to prevent false detections.
📉 Absence and automatic temperature reduction
Absence does not simply mean “no movement for a few seconds”. In smart electric radiators, absence is defined as the lack of detected movement over an extended period of time: only then can the system be sure that a room is unoccupied.
🔥 Step temperature reduction in Radialight electric radiators
Radialight electric radiators for the home equipped with a presence sensor use a gradual, step-based temperature reduction:
- -1 °C after 60 minutes without presence
- -1 °C after a further 30 minutes
- -1.5 °C after an additional 60 minutes
After 120 minutes of absence, the temperature is reduced by -3.5 °C compared to the set comfort level. The return to the original comfort temperature happens automatically once presence is detected in the room for at least 10 minutes. For example, if a comfort temperature of 19 °C is set and you leave the room for more than 2 hours before returning, the system will behave as follows:

Radialight electric bathroom fan heaters follow a faster logic, as bathrooms are typically occupied for shorter periods. For this reason, both the activation of the comfort temperature and the return to the energy-saving mode are designed to be quicker.
- 📉 Temperature reduction of -3.5 °C after 10 minutes of absence
- 📈 Return to comfort temperature after 2 minutes of presence
✅ Practical benefits
- Comfort guaranteed only when needed
- Automatic reduction in energy consumption
- Smart management with no manual intervention
- Adaptation to real room usage
