CO₂CONTROL sensor

The wired CO₂Control sensor measures carbon dioxide concentration in the air and controls the operation of the heat recovery unit (HRV) based on the building's fresh air demand. As occupant activity increases, the concentration of carbon dioxide in rooms increases, resulting in the need for more efficient ventilation. When a preset threshold is exceeded, the HRV is forced to run at speed 3. When the CO₂ concentration in the room drops, the HRV resumes operation according to the weekly schedule.
