Rhino 2EC + RH Fan Controller

The Rhino 2EC + RH Fan Controller is an environmental controller for EC intake and extraction fans. A built-in digital probe monitors air temperature and humidity, with a light sensor enabling separate day and night setpoints. Dual EC outputs allow independent speed control of intake and outtake, while an onboard fan balancer maintains negative pressure accurate to around 1% of fan speed. When heat or humidity rises, the unit ramps fans automatically, keeping conditions stable and reducing energy use and wear. Minimum and maximum fan speeds can be set, and the controller pairs directly with Rhino EC Ultra fans (and compatible Rhino EC models) using the appropriate cables. It’s a plug-and-play solution for precise, automated grow-room climate management.
