- Set your minimum fan speed to 20–30% to maintain continuous fresh air exchange — never let it drop to zero.
- Use Day/Night mode to reduce fan speed during dark periods — quieter overnight and easier on your power bill.
- Mount the sensor probe at canopy level for accurate temperature and humidity readings where it actually matters.
- Revisit your setpoints at each growth stage — a flowering room runs warmer and drier than a propagation space.

Pairs Well With

Frequently Asked Questions
Does this controller work with non-Headwind fans?
No. The HVC Smart EC Fan Controller PRO is designed exclusively for Headwind HVC EC fans. It draws power from and communicates directly with those fans — it will not function correctly with other brands.
Can it respond to temperature and humidity at the same time?
Yes. In Auto Mode the controller reads both temperature and humidity simultaneously from the integrated probe and adjusts fan speed to keep conditions within your setpoints — whichever trigger is reached first drives the response.
How many fans can I connect?
Up to four Headwind HVC EC fans can be connected and controlled simultaneously from a single HVC Smart EC Fan Controller PRO.
Does it need a separate power supply?
No. The controller is powered directly through the connected Headwind HVC EC fans — no external power cord or adapter is required. Setup is minimal.
Will I know if a connected fan develops a fault?
Yes. The controller monitors each connected fan individually. If a fan stops working or behaves abnormally, it will trigger an alarm alert so you can act before your environment is affected.
