CO₂ Controller with Remote Probe — Automatic CO₂, Temperature & Humidity Management

VDL CO₂ controller for greenhouses — Precise management of CO₂, humidity & temperature

In indoor growing, climate stability is key to success. This VDL CO₂ controller precisely measures and manages CO₂, humidity, and temperature in your grow space. Automate your generator or exhaust system and maintain a consistent environment conducive to controlled growth.

Automated CO₂ control for stable cultivation

Thanks to real-time CO₂ measurement and an integrated control relay , you can automatically activate your generator or ventilation system. This keeps your target CO₂ level constant and prevents sudden fluctuations.

A controlled climate. More uniform and productive plants.

• NDIR accuracy — a reliable measure of CO₂ for consistent automated decisions.
• Triple display — CO₂, humidity and temperature visible simultaneously.
• Smart relay — activates or deactivates your equipment according to the programmed target zone.
• Historical graph — visualization of trends over 1 minute, 1 hour, 1 day or 1 week.

High-precision NDIR CO₂ sensor

NDIR technology ensures stable and reliable carbon dioxide measurements. You benefit from a resolution of up to 1 ppm in narrow ranges, ideal for fine-tuning your enrichment strategy. Thanks to its fast response time (approximately 30 seconds to 2 minutes) , the system reacts quickly to changes. You'll observe a more consistent level that your plants can better utilize.

Plant Mode & Human Mode for adapted piloting

Plant Mode activates the relay when the CO₂ level drops below the target value. This optimizes enrichment during the light phase. In Human Mode , the relay activates when the threshold is exceeded, in order to ventilate. With the center + zone setting , you precisely define your ideal range. You adapt your system to your actual environment.

Color LED display and integrated alarms

The large color LED display ensures clear readability, even from a distance or in low light. You can monitor the current rate and its graphical evolution at a glance. The configurable audible alarm alerts you in case of a critical exceedance. With automatic day/night detection , the control adapts to your light cycle. You gain peace of mind and responsiveness.

How to use the CO₂ VDL controller?

The installation is simple and designed for professional use in a grow room.

• Position the probe — install it at plant height, away from direct sources of CO₂.
• Connect your equipment — plug generator or ventilation into the dedicated relay socket.
• Define your target area — set center and range according to your objectives.
• Error to avoid — do not place the probe near your face or a direct gas outlet, this will distort the measurement.

Once configured, the system automatically controls your climate and stabilizes your CO₂ level.

Compatible with CO₂ generators and ventilation systems

This CO₂ controller can be integrated into the majority of indoor installations powered by 100–240V.

• CO₂ generators — automatic activation below the programmed threshold.
• Extraction systems — triggered in case of overfilling.
• Greenhouses and enclosed rooms — suitable for residential and commercial environments.

Joseph's advice: "A high-performance CO₂ controller is useless if the probe is poorly positioned. Always place it in the area where your plants breathe. A good CO₂ controller should measure the actual microclimate, not an isolated area of your room."
