Autopilot Digital CO2 Controller with Integrated Sensor

The CO2 exhaust mode automatically triggers exhaust fans when CO2 levels exceed safe limits for human occupancy. This is crucial for worker safety in enclosed growing areas where CO2 enrichment could create dangerous conditions. You can set custom PPM thresholds to ensure immediate ventilation when workers enter the space.

Integrated sensors eliminate cable runs and potential connection issues while simplifying installation. The APC8400's built-in sensors provide accurate CO2 monitoring without external probe placement concerns. This design is ideal when the controller can be positioned within the monitored environment for reliable, maintenance-free operation.

The day/night detection system automatically adjusts CO2 delivery based on lighting cycles, since material only utilizes CO2 during photosynthesis when lights are on. During night cycles, the green backlit screen dims and only illuminates for 30 seconds during selections, preventing light pollution while maintaining easy operation.

Yes, the CO2 enrichment mode supports both tank/regulator setups and CO2 generator systems. The controller provides the appropriate control signals for either application, making it versatile for different CO2 delivery methods. Simply select the enrichment mode and configure the setpoint for your specific system type.

For growing optimization, typically set 1000-1500 PPM during light periods. For safety exhaust applications, set 1000 PPM or lower to trigger ventilation before levels become unsafe for humans. The APC8400's 0-5000 PPM range accommodates both applications with precise control over activation thresholds.

The 7-day memory records and reviews past CO2 levels allowing you to analyze patterns, identify optimal timing for CO2 delivery, and fine-tune your environmental control strategy. This historical data reveals how quickly CO2 is consumed and when replenishment is most effective for maximum growing efficiency.

ETL registration indicates the controller meets electrical safety standards for commercial and residential use. This certification ensures the device has been tested for safety, performance, and compliance with North American electrical codes, providing confidence for professional installations and regulatory compliance.

The APC8400 features simple mode selection through the digital interface. You can easily switch between CO2 enrichment mode (for growing optimization) and CO2 exhaust mode (for safety applications) using the controller's menu system. Each mode maintains separate setpoint and deadband settings for quick transitions between applications.
