TechGrow CO₂ T-Micro Controller is an electronically controlled device that measures and regulates the CO₂ level in the room. It automatically switches between day/night settings using the external CO₂ sensor and light sensor. TechGrow CO₂ T-Micro Controller has a sturdy housing and is equipped with an LCD display. In addition, the T-Micro's built-in calibration function allows the CO₂ sensor to be calibrated against outdoor air.

Specifications:

• Plug & Play can be used in small or very large rooms
• Extremely accurate external CO₂ sensor, manufactured by SenseAir® Sweden, a leading manufacturer of CO measurement equipment₂
• Built-in function for calibrating the CO₂ sensor against outside air
• Can be set from 300 to 2000 ppm
• The sensor takes a measurement every second
• Switches the CO₂ source (CO₂ generator, CO_2-cylinder) on/off via a 230V relay
• Memory function in case of power outages for the setpoint and hysteresis
• Automatic detection of 110V-230V
• The LED indicates when CO is being dosed₂
• The external CO₂ sensor has a built-in light sensor to switch automatically between day/night settings
• Automatically detects a broken cable or poor connection to the connected sensors
• The sensor is connected using a standard UTP network cable

The VDL Digital CO₂ Controller is a wall-mounted controller designed to accurately measure and automatically regulate carbon dioxide (CO₂) concentrations in enclosed spaces. It uses NDIR sensor technology and an external probe to monitor CO₂, temperature, and humidity. Suitable for greenhouses, grow rooms, laboratories, and workspaces.

Detailed specifications

• Measurement technology: NDIR sensor – ensures stability and durability.
• Display: Color LED or LCD screen with separate sections for CO₂, temperature, humidity, current time, and alarms.
• Device control: Built-in relay with a socket allows external devices (e.g., a CO₂ generator or fan) to be activated/deactivated according to CO₂ levels.
• Smart modes:
  • Plant Mode – activates a CO₂ generator when levels are low.
  • Human Mode – starts ventilation when CO₂ levels are high.
• Day/Night sensor: Automatically detects lighting and optimizes operation according to day or night mode.
• Alarms: Programmable audible alerts for excessively high CO₂ concentrations.
• Historical data: Recording and graphing of maximum and minimum values for the past week.
• Measurement range and accuracy:
  • CO₂: 0–9999 ppm
  • Temperature: 0–50 °C
  • Humidity: 5–95 % RH
  • Resolution:
    • CO₂: 1 ppm (0–1000); 5 ppm (1000–2000); 10 ppm (>2000)
    • Temperature: 0.1 °C
    • Humidity: 1 % RH
  • Accuracy:
    • CO₂ < 2000 ppm: ±50 ppm or ±5%
    • CO₂ > 2000 ppm: ±10%
    • Temperature: ±0.6 °C
    • Humidity: ±5 % (25 °C, 10–90 % RH) / ±7 % (other ranges)
• Probe with cable: External probe with a cable approximately 4.5 m long for flexible positioning in the growing environment.
• Dimensions and weight:
  • Control panel: approx. 15.6 × 11.6 × 3.9 cm
  • Probe: approx. 11.7 × 3.5 × 2.7 cm
  • Weight: ~750 g
• Operating conditions: 0–50 °C, 5–95 % RH
• Warm-up: Ready to use after about 30 seconds.

Usage recommendations

• Mount the wall controller in a convenient location, ensuring the probe cable is positioned among the plants for precise measurements.
• Choose “Plant Mode” to automate CO₂ delivery using a generator. Or “Human Mode” for safe ventilation when levels are excessive.
• Use the day/night function to optimize resource savings and maintain safe conditions.
• Program alarms for high concentrations and set the desired CO₂ levels and hysteresis.
• Track weekly minimum and maximum values to analyze and optimize the control process.

Summary – Benefits

• Accuracy and reliability: NDIR technology and high measurement accuracy.
• Integrated control: Control external devices based on CO₂ levels for effective automation.
• Precise monitoring: CO₂, temperature and humidity on one screen.
• Versatile: Suitable for greenhouses, laboratories, home growing or workspaces.
• Future maintenance: Probe replacement for extended service life.
• Easy to use: Quick setup, calibration and programming.

Thanks to this unique combination, you can dose CO₂ during the day, while the fan extracts excess CO₂ and moisture produced by your plants at night. The TechGrow Pro CO₂ Controller T-2 14A increases ventilation at high temperatures, but this can be overridden by setting the temperature setpoint very high. This completely redesigned controller is compatible with many other TechGrow devices. The TechGrow Pro CO₂ Controller T-2 14A measures, controls, and displays CO₂, humidity, and temperature values from the connected sensors, and records min / max values.

With easy-to-use fan control via the "Box-menu".

Includes quick menus that offer a brief overview of all settings and measurements.

Features:

• all CO₂ settings are the same as those of the TechGrow Pro CO₂ Controller T-1
• extraction of excess CO₂ and humidity at night
• unique calibration menu for setting up any grow box, regardless of size
• LED indicator for CO₂ dosing, light detection, and a stable climate
• simultaneously controls CO₂, temperature, and humidity
