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

Features:

• Plug & Play can be used in small or very large rooms
• highly accurate external CO₂ sensor, manufactured by SenseAir® Sweden, a leading manufacturer in CO₂ measurement
• built-in function for calibrating the CO₂ sensor against outdoor 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 backup for the set point and hysteresis in the event of power interruptions
• automatic 110V-230V detection
• the LED indicates when CO₂ is being dosed
• the external CO₂ sensor has an integrated light sensor to automatically switch between day / night settings
• automatically detects a broken cable or poor connection of connected sensors
• the sensor is connected using a standard (UTP) network cable

The VDL Digital CO₂ Controller is a wall-mounted controller designed for precise measurement and automatic regulation of carbon dioxide (CO₂) concentration in enclosed spaces. It uses NDIR sensor technology and an external probe to monitor CO₂, temperature and humidity. Convenient for greenhouses, grow rooms, laboratories and workspaces.

Detailed features

• Measurement technology: NDIR sensor – ensures stability and durability.
• Display: Colour LED or LCD screen with separate zones for CO₂, temperature, humidity, current time and alarms.
• Device control: Built-in relay with plug, allowing external devices (e.g. a CO₂ generator or fan) to be activated/deactivated according to CO₂ levels.
• Intelligent modes:
  • Plant Mode – activates the CO₂ generator at low values.
  • Human Mode – starts ventilation at high CO₂ levels.
• Day/Night sensor: Automatically detects lighting and optimises operation according to day or night mode.
• Alarms: Programmed audible warnings for excessively high CO₂ concentrations.
• Historical data: Recording and graphical display 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 about 4.5 m long for flexible positioning in the carbon 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 for use after about 30 seconds.

Recommendations for use

• Install the wall controller in a convenient place and ensure the probe cable is positioned among the plant canopy for precise measurements.
• Select “Plant Mode” to automate CO₂ supply through a generator. Or select “Human Mode” for safe ventilation when levels are excessive.
• Use the day/night function to optimise resource savings and maintain safe conditions.
• Program alarms for high concentrations and set the desired CO₂ values and hysteresis.
• Monitor weekly minimum and maximum values to analyse and optimise the control process.

Summary – Benefits

• Accuracy and reliability: NDIR technology and high measurement accuracy.
• Integrated control: Controls external devices by CO₂ level for efficient automation.
• Precise monitoring: CO₂, temperature and humidity on one screen.
• Flexibility: Suitable for greenhouses, laboratories, home growing or workrooms.
• Future support: The probe can be replaced for long-term durability.
• 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 the humidity produced by your plants at night. TechGrow Pro CO₂ controller T-2 14A increases ventilation at high temperatures, but this can be overridden by setting a (very) high set temperature. This fully redesigned controller is compatible with many other TechGrow devices. TechGrow Pro CO₂ controller T-2 14A measures, controls and displays CO₂, humidity and temperature values from connected sensors, and records min / max values.

Easy-to-use fan control via the "Box-menu".

Includes quick menus that provide 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 every box, regardless of size
• LED indicator for CO₂ dosing, light detection and a stable climate
• controls CO₂, temperature and humidity simultaneously
• all settings are retained during power outages
• all setpoint, hysteresis and alarm values are individually adjustable
• quick menu for a quick overview of all settings and measurements
• the fan can be operated automatically or manually
• the fan controller is adjustable in 10% increments
• includes a unique feature allowing the fan to be adjusted in two simple steps
• can be connected to multiple TechGrow devices
• can be connected to the Techgrow Datalogger (DL-1)
