Rhino 1EC Fan Controller

Rhino 1EC Fan Controller is a single‑channel, thermostatic speed controller for EC inline fans. It uses a plug‑in temperature probe and three analogue dials: target temperature (20–30°C), maximum fan speed, and minimum fan speed. After setup, it automatically varies fan speed to hold the set temperature, maintaining airflow without an external power supply. The unit connects directly to Rhino Ultra EC fans via the fan’s control port and is powered by the fan; a 0.3 m three‑pin adaptor/cable supplied with Rhino fans is used for connection. Designed for out‑take fans and EC motors only (not AC), the 1EC provides straightforward, reliable ventilation control for compact and mid‑size grow spaces. Minimum and maximum speed limits prevent stalls and reduce noise during cooler periods.
