The iO HVAC Controls CO2-TH is a wall-mount monitor and controller for CO₂, temperature, and humidity that triggers fresh-air damper modulation or demand ventilation whenever indoor conditions exceed setpoint — keeping air fresh and efficient.

Key Features & Benefits

• CO₂, temperature & humidity sensing — complete indoor-air-quality monitoring in one device.
• Demand-controlled ventilation — modulates fresh air only when it's needed.
• Energy-smart operation — reduces over-ventilation and wasted energy.

Ideal For

Commercial and residential spaces that want automatic, demand-based ventilation driven by real indoor-air-quality data.
