It monitors your grow room environment continuously, adjusts your intake and extraction fan speeds in real time, and controls additional equipment — heaters, humidifiers, lights — all from a single point. No manual adjustments. No guesswork.

Here's how it works:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTemperature and humidity control\u003c\/strong\u003e\u003cbr\u003eSet your target temperature and humidity range for day and night. The built-in sensors detect changes in your grow room and automatically adjust your intake and extraction fans to maintain those settings. Too hot — fans speed up. Too cold — they slow down. Humidity too high — extraction increases. Humidity too low — extraction backs off. All automatic, all the time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFan speed programming\u003c\/strong\u003e\u003cbr\u003eYou set minimum and maximum fan speeds for day and night, so the controller has guardrails. This means your fans won't spin to ridiculous speeds just because it's warmed up slightly, and they won't drop too low when it's cool. Better for equipment longevity, better for energy bills.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMulti-equipment control\u003c\/strong\u003e\u003cbr\u003eTwo fully programmable sockets let you control other equipment based on your environmental data. Run a heater on cold nights? Plug it in. Humidifier in winter? Same socket. The controller triggers them on and off to maintain your environment. Lights up to 1200w can also be controlled for scheduling.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDay and night cycling\u003c\/strong\u003e\u003cbr\u003eProgramme completely different settings for your lights-on and lights-off periods. Your grow room doesn't need the same conditions at night as during the day — the V2 handles that automatically when you switch your lights on and off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor small-to-medium rooms\u003c\/strong\u003e\u003cbr\u003eThis controller is best suited to spaces running 2–4 fixtures (typically 600w–1200w total lighting), which covers most home and semi-commercial setups. If you're running serious lighting or growing through summer heat, this will prevent the temperature stress and humidity spikes that kill yields and invite mould.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan control:\u003c\/strong\u003e AC and EC fans (both intake and extraction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntake fan output:\u003c\/strong\u003e 10A maximum, 2300W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtraction fan output:\u003c\/strong\u003e 10A maximum, 2300W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable socket 1:\u003c\/strong\u003e 10A maximum, 2300W (non-lighting equipment)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable socket 2:\u003c\/strong\u003e 10A maximum, 2300W (non-lighting equipment)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLighting control:\u003c\/strong\u003e Up to 1200W maximum per circuit (due to high start-up surge)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature sensor:\u003c\/strong\u003e Built-in calibration, day and night settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity sensor:\u003c\/strong\u003e Built-in calibration, day and night settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e LCD screen with automatic dimming and green LED backlight (non-disruptive to plants)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData logging:\u003c\/strong\u003e Records temperature and humidity at regular intervals for performance tracking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDay\/night programming:\u003c\/strong\u003e Separate settings for temperature, humidity, minimum and maximum fan speeds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Plug-and-play design, built-in fan balancer, dump function for closed-loop environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e CE certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Works with Systemair Revolution EC and AC fan range (and other standard AC\/EC fans)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSmall-to-medium growers running 2–4 fixtures who want to automate their environment\u003c\/li\u003e\n\u003cli\u003eAnyone growing through summer or in naturally warm climates where temperature control is critical\u003c\/li\u003e\n\u003cli\u003eGrowers who've had mould problems and need active humidity management\u003c\/li\u003e\n\u003cli\u003eExperienced growers looking for reliable, long-term equipment without paying for unnecessary complexity\u003c\/li\u003e\n\u003cli\u003eAnyone who doesn't want WiFi connectivity headaches — just solid, dependable hardware\u003c\/li\u003e\n\u003cli\u003eGrowers running intake and extraction fans who want them balanced intelligently, not controlled separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly suited to setups where \u003cstrong\u003estability and simplicity matter more than mobile app monitoring\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eThis is one of the most popular controllers on the market for a reason — it does what it's supposed to do, reliably, without the drama.
