The Demand-Air™ Kit (DA-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 Belimo brushless DC motor. To preclude over-ventilation, the damper begins to open at 800ppm and is full open by 1200ppm.
24VAC Transformer included.
