The Demand-Airâ„¢ Economy Kit (DAE-CO2-XX) is the simple answer to demand response ventilation. The Carbon Dioxide Sensor monitors concentrations in the space and causes the damper motor to modulate open or closed as required to maintain a healthful indoor environment while reducing operating cost. The damper is available in any round size you need. The kit features a high-quality Siemens motor. To preclude over-ventilation, the damper begins to open at 800ppm and is full open by 1200ppm.
