HVC Smart EC Fan Controller Pro

The HVC Smart EC Fan Controller PRO is a dual-channel controller for EC inline fans, built for precise, automated climate management in ducted grow rooms and tents. A 2.8-inch TFT interface provides clear readouts and quick navigation, while the included 5 m temperature-and-humidity sensor feeds live data for responsive control. Unlike basic speed dials, the PRO offers mode-based automation. Day/Night profiles switch via the integrated light sensor, Auto Trigger reacts to high/low temperature and humidity thresholds, and Schedule/Timer/Cycle options let you run extraction exactly when you need it. Min/Max speed limits and smooth EC ramping keep airflow stable and quiet-leaning at low RPMs. Two independent outputs (Ch1 and Ch2) allow you to control intake and exhaust or two zones from one controller, with fan-fault detection and alarm prompts for peace of mind. The unit draws low-voltage power from the connected EC fan channel (no separate mains adaptor needed) and mounts cleanly at eye level with the supplied bracket. Designed for compatibility with HVC EC fans (and other EC fans using the same control interface), the PRO focuses on reliable, temperature- and humidity-aware automation to maintain a consistent environment across propagation, veg and bloom.

HVC Smart Speed Controller

Headwind HVC

HVC Smart Speed Controller

The HVC Smart Speed Controller is a temperature-driven controller for EC inline fans that delivers precise, stable airflow control without the need for a separate power supply. It draws power from the connected EC fan and uses an NTC thermal probe to read room temperature in real time. Two operating modes provide flexibility: Auto mode maintains a user-set temperature by automatically adjusting fan speed in steps, while Manual mode holds a constant speed for fixed extraction. A programmable high-temperature alarm can override settings to protect the environment when conditions exceed your threshold. The unit provides four 3.5 mm control outputs to manage up to four compatible EC fans from a single controller, keeping wiring tidy and control centralised. Clear on-device controls make setup quick, and wall-mount hardware is included for a clean installation. Designed specifically for Headwind HVC EC fans (and other EC fans using the same control interface), this controller focuses on dependable temperature-based control. Humidity targets, scheduling and light-based modes are reserved for the separate HVC Smart EC Fan Controller PRO.
