Rhino 2EC Fan Controller

Rhino 2EC Fan Controller is an analogue, EC-only environmental controller for managing intake and extraction in tandem. It regulates grow-room temperature via a thermostatic set point (20–30°C), while separate dials set maximum and minimum fan speeds to avoid sudden swings. A dedicated offset control establishes a fixed differential between intake and outtake, maintaining negative pressure to keep odour and heat under control. The unit powers itself from connected Rhino Ultra EC fans and requires no external supply or additional relay boxes. Designed for dual-fan setups, it suits tents and rooms where balanced airflow and stable temperatures are essential. Compatible with Rhino Ultra EC fans and related 3‑pin adaptors, it offers simple, reliable ventilation management from a single controller. Includes a temperature probe for accurate canopy-level sensing.
