One hub to run every zone of your grow room The TrolMaster Hydro-X Pro (HCS-2) is an advanced multi-zone environmental controller built for professional indoor growing and larger hydroponic systems. Acting as the central hub for the whole room, it manages temperature, humidity, CO2 and lighting from a single 10-inch touchscreen with web-based monitoring software. Unlike standard single-zone controllers, the Hydro-X Pro supports multiple sub-zones, linking specific sensors to specific control modules so conditions stay consistent across the entire canopy for healthier plants and higher yields. What's Included Hydro-X Pro Controller (HCS-2) 4-in-1 Environmental Sensor with LCD display RJ12 connection cable for system integration Key Benefits Multi-zone control with sensors and modules assignable to specific sub-zones 10-inch touchscreen for on-unit monitoring and configuration Independent control of temperature, humidity, CO2 and lighting Up to 50 sensors and 50 control modules per system Built-in crop scheduling with programmable multi-week grow-cycle recipes Web-based software for remote monitoring and advanced control Compatible with Hydro-X device stations and selected Aqua-X modules, including grow-media sensors Uneven results between different areas of the same room? Large rooms and commercial hydroponic setups rarely hold identical conditions everywhere. Temperature, humidity and light can vary from one end of the canopy to another, and a single averaging controller leads to patchy growth and inconsistent yields. The Hydro-X Pro splits one space into sub-zones, linking sensors to the controls that serve each area, while programmable multi-week schedules automatically shift conditions to mimic natural changes through veg and flower. How to Use Install the Hydro-X Pro in the grow room and power the unit. Connect the included 4-in-1 environmental sensor via the RJ12 cable. Add compatible Hydro-X device stations, sensors and lighting adapters to expand control. Assign modules and sensors within the interface to create control zones. Configure temperature, humidity, CO2 and lighting schedules for each zone. Build multi-week crop schedules with the built-in calendar for automated control. Connect to the internet to monitor and adjust via the web platform or mobile app. Technical Specifications Display: 10-inch colour touchscreen Controlled parameters: Temperature, humidity, CO2, lighting Capacity: Up to 50 sensors and 50 control modules per system Zoning: Multiple sub-zones with sensor-to-module linking Connectivity: RJ12 device network, web-based software and mobile app Compatibility: Hydro-X device stations and selected Aqua-X components Sensor: MBS-PRO 4-in-1 with 16 ft RJ12 cable Sensor accuracy: ±0.36°F, ±3% RH, ±30 ppm CO2 Max device connection distance: 1000 m Max HID fixtures: 256 per channel, 2 channels Max load per device station: 10A at 100-240V AC per plug-in module App: TrolMaster app plus pro.trolmaster.com Power supply: 100-240V AC, 50/60 Hz, 0.5A Lighting channels: 2 channels, unlimited fixtures via adapters Setpoint ranges: 40-100°F, 20-99% RH, 300-2500 PPM Weight: 3.06 kg
