The iO HVAC Controls CO2 Two-Position Demand Ventilation Kit controls outdoor-air intake based on indoor CO₂ levels — the two-position actuator fully opens the fresh-air damper when CO₂ exceeds setpoint and fully closes it once levels fall back below the threshold.

Key Features & Benefits

• CO₂-driven ventilation — brings in fresh air only when it's actually needed.
• Two-position actuation — simple, reliable open/close fresh-air control.
• Energy-smart operation — avoids continuous over-ventilation.

Ideal For

Commercial spaces that want straightforward, CO₂-based demand ventilation with reliable two-position control.
