The HVC Smart EC Fan Controller PRO V2 reads temperature and humidity through a 5m probe and drives two Headwind HVC EC fans on their own channels, so you can set an intake and an exhaust at different speeds, trigger them on heat or humidity, run a timer, or get an alarm when the room drifts. It is powered straight from your HVC fan, so there is no extra power point to find. Built for growers running one tent or a small room with HVC EC fans. The honest bits: it controls two fans, not four, and it only works with Headwind HVC EC fans.\u003c\/p\u003e\n\n\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; margin-bottom: 2rem;\"\u003e\n\u003cdiv style=\"background: #f4f9f4; border-left: 4px solid #2e5e2e; padding: 1rem 1.2rem; border-radius: 6px;\"\u003e\n\u003cstrong style=\"display: block; margin-bottom: 0.3rem; color: #2e5e2e;\"\u003eTwo Fans, Two Speeds\u003c\/strong\u003e\u003cspan style=\"font-size: 0.9rem; color: #444;\"\u003eSeparate channels for Fan 1 and Fan 2.
