The SigilVentus Smart EC Fan Controller Pro is the climate brain for your SigilVentus EC fans. The included probe reads temperature and humidity in your grow space, and the controller adjusts fan speed automatically to hold the conditions you set. Timing functions and differential air pressure adjustment round it out — set your targets once and let the room manage itself.

Temp and Humidity in OneThe Pro's probe reads both temperature and humidity — the step up from the standard thermal-only SigilVentus controller.
Auto-ControlSet your target conditions and the controller trims fan speed up and down to hold them — no daily dial-fiddling.
Timing FunctionsSchedule fan operation around your light cycle instead of running flat out around the clock.
Air Pressure AdjustmentBuilt-in differential air pressure adjustment lets you balance intake and exhaust for stable airflow.

The Grow Guys Tips
  • Connect the controller before powering the fan — SigilVentus EC fans do not function without a speed control connection
  • Position the probe at canopy level, away from lights and out of the fan's direct airflow
  • Running slight negative pressure keeps odours moving through your carbon filter — the pressure adjustment makes that easy to dial in

How to Set It Up

1Connect the controller to your SigilVentus EC fan before powering up — the fan won't run without it.
2Position the probe at canopy level, clear of lights and direct airflow.
3Set your target temperature and humidity, and any timing schedule you want.
4Let Auto-Control take over — the controller holds your set conditions from here.

Common Questions

Does it control humidity as well as temperature?

Yes. The Pro reads both temperature and humidity through its probe and regulates fan speed to hold your set conditions — that's the main step up from the standard SigilVentus thermal controller, which works from temperature only.

Does it come with the probe?

Yes. The temperature and humidity probe is included in the box.

Will it work with any inline fan?

No. It's designed for SigilVentus EC fans. AC fans and other brands' EC fans run from their own controllers.

Do SigilVentus fans run without a controller?

No. SigilVentus EC fans do not function without a speed control connection — connect the controller before powering up the fan.

Growers First, Retailers Second

Welcome to The Grow Guys

We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
