The TrolMaster Hydro-X Environment Control System (HCS-1) is a single‑zone, modular environmental controller for grow rooms and greenhouses. The HCS‑1 serves as the system brain and ships with a 3‑in‑1 temperature/humidity/photocell sensor, plus an RJ12 cable set for quick installation. Through compatible device stations and light adapters, Hydro‑X can regulate most brands of grow lights, mini‑split or HVAC equipment, commercial humidifiers and dehumidifiers, and CO2 generators or regulators. The controller supports additional sensors, including optional CO2 and PAR sensors. Settings and alerts can be monitored and changed via the free TrolMaster app, and operating data can be logged to a microSD card. The unit operates on 100–240 VAC and provides flexible, hard‑wired expansion to build a complete environment control solution.
