Almost all TechGrow controllers and sensors are compatible with one another, optimizing ease of use and keeping expansion affordable. Recently, TechGrow started offering controllers and sensors separately, so you can mix and match them as needed. This makes it possible to combine three different controllers with one sensor, e.g. a CO₂ controller, a climate controller and Humi Dual, using only an S-4 sensor. All values measured by your sensor can be saved on the TechGrow Datalogger DL-1. To find out which sensor is compatible with your TechGrow controller, refer to your controller manual. Each Pro Series controller displays the current CO₂, temperature and humidity values, and also records min/max values.

TechGrow Clima Control ECO 8A can control up to 2 fans and precisely create the right climate in your room. It ramps up more slowly than other controllers to achieve a more stable climate. The controller is exceptionally easy to use - the rotary knobs let you easily set the desired temperature and hysteresis, as well as the fan's minimum and maximum speed. The modern software does the rest!

Humi Heavy is specially designed to control powerful dehumidifiers. Thanks to the additional heavy-duty components, this controller can switch devices up to 10A.

• Power supply: from 100 to 240V
• Mains frequency: 50 to 60 Hz
• Power consumption: 3W
• Switching capacity: 2300W / 10A
• RH setting range: 10 - 90% relative humidity
• RH +/- setting range: 0 - 5% air humidity

Humi Heavy is easy to install and can regulate from 10% to 90% relative humidity. The clear LCD screen provides convenience when setting and reading values, while the LED backlight shows whether Humi Heavy is active. Finally, the set point and hysteresis remain stored in the event of a power failure.

Features:

• Extremely accurate external humidity sensor
• The display shows the minimum / maximum humidity value
• Can regulate relative humidity from 10 to 90%
• The sensor takes a measurement every second
• Switches the connected device with a 230V relay
• Memory for set point and hysteresis in the event of a power failure
• LED indicator shows whether Humi Heavy is active
• LCD display
• Extra-heavy-duty relay (10A)
• Supplied without a sensor; various sensors are available separately

TechGrow - Clima Micro Plus 5A (Min speed) controls the minimum speed of your fan until the desired temperature is reached or maintained in the grow room. This efficient controller is easy to operate - it has only two rotary knobs - for setting the minimum fan speed and the desired room temperature. There is also an option to set the hysteresis (1°C – 5°C).

• Controls the minimum fan speed until the desired temperature is reached or maintained
• Minimum fan speed setting range: 10% - 100%
• Temperature setting range: 15°C - 35°C
• Hysteresis setting range: 1°C - 5°C
• Minimum required sensor: TempProbe (not included)

Features:

• Controls the minimum fan speed to reach or maintain the desired temperature
• The display shows the current temperature, as well as the set temperature, fan speed, minimum and maximum measured temperature, and hysteresis
• The LED indicates a stable climate or high temperature
• The set minimum fan speed and temperature are retained in the event of a power outage
• Minimum fan speed setting range: 10% - 100%
• Temperature setting range: 15° - 35°C
• Hysteresis setting range: 1°C - 5°C
• The display updates every second

This fully redesigned controller is as easy to use as the other TechGrow devices with which it is compatible. The TechGrow T-1 Pro CO₂ controller measures and controls the CO₂ level in a room. It automatically switches between day and night modes through the external sensor.

• Power supply: from 100 to 240V (automatic)
• Consumption: 3W (with sensor, without CO₂ source)
• CO₂ system setting range: 300 to 2000ppm
• CO₂ +/- setting range: 20 to 200ppm (we recommend 50ppm)
• (Hysteresis / frequency band)
• Measurement time: 1 measurement per second

Note: the sensor is sold separately!

Our new Pro range features a hard, robust housing that is splash-resistant and fully controlled via the single Push & Turn button. The TechGrow Pro CO₂ T-1 controller also has min / max memory to show the minimum and maximum CO₂ value in a given area. The external CO₂ sensor is connected by UTP cable as standard, allowing you to take measurements anywhere in the area, ranging from 300-2000ppm or 300-10000ppm. With its new built-in dosing delay and timer, it offers the perfect solution for precise and accuracy-dependent dosing. The TechGrow Pro CO₂ T-1 controller also comes with a built-in dosing counter, allowing you to monitor CO₂ usage. The TechGrow Pro CO₂ T-1 controller now offers an easier way to make long-term progress and achieve overall improvement. Managing your growing environment will be better than ever!
