How does the VELUX ACTIVE with NETATMO algorithm control my indoor climate?

 VELUX ACTIVE provides two main algorithms for the automatic control of your indoor climate. The two algorithms are:

1) A ventilation algorithm that automatically controls your VELUX skylights to regulate room temperature, humidity and carbon dioxide (CO₂). The ventilation algorithm relies on indoor measurements made by your sensor and weather forecasts retrieved from the Internet. By using this information, the VELUX ACTIVE algorithm can decide whether ventilating the room will improve the indoor climate, or whether the skylight should remain closed because the indoor climate cannot be improved.

To ensure a constant supply of fresh air, the algorithm also has an air recycling functionality, that ventilates the room on a regular basis (every 1-6 hours) for a period of 5-15 minutes depending on indoor and outdoor conditions. 

2) A blind algorithm which is designed to prevent potential overheating by closing your blinds to block out the sun when appropriate. The blind algorithm also relies on weather forecast information to make smart decisions based on indoor and outdoor conditions.
