Rhino EC Fan Controller – Digital Thermostatic Speed Controller for EC Extraction Fans

The Rhino EC Fan Controller gives you precise, automated control over your grow room’s temperature and fan speeds. The digital LCD touchscreen interface offers both automatic and manual operating modes, making it straightforward to configure and walk away with confidence.

In automatic mode, the included thermal probe continuously monitors room temperature and adjusts connected fan speeds to maintain your target environment. In manual mode, fans run at a fixed, consistent speed regardless of ambient temperature — ideal for stable grow environments. Compatible with all Rhino Ultra EC fans and controllable across 0–100% power in 20% increments.

The controller can be powered directly by the connected fan, removing the need for an additional external power supply. This also provides built-in protection against electrical surges caused by overloaded supplies and ensures the environment remains stable if an external power supply fails. Each unit is backed by a 2-year warranty.
