The following symbols are used in this installation manual to draw the reader’s attention to safety aspects and important information:

Point of attention

Risk of compromised performance or damage to the ventilation system

Risk of personal injury

Features and benefits

The CO2 Sensor measures the amount of CO2 in the air of the room in which this sensor is installed. The device sends the results to the ventilation system. If the CO2 level is too high, the system regulates the ventilation based on the maximum CO2 values.

In this way, healthy air quality in the room is maintained.

Reducing high CO2 values in the home is conducive to concentration, good sleep quality, and helps prevent headaches

Advice for manual ventilation modes

The CO2 Sensor is intended for automatic ventilation. If installed correctly, it will provide sufficient ventilation in the room where it is installed. In certain cases, it is recommended to select a manual ventilation mode:

• Manual mode 2 (normal): for a few peopl in a living room without a CO2 Sensor
• Manual mode 3 (high): for many people in rooms without a CO2 sensor
