Hydro-X Controller with 3-in-1 Sensor

Manage Lights, Climate, and CO2 From One Modular Controller

The TrolMaster HCS-1 is a single-zone Hydro-X controller built around a modular device-station design, so a grower adds the specific outlets and stations a given room needs instead of paying for fixed, unused capacity built into a sealed box. Out of the box, it manages grow lights, HVAC and mini split units, dehumidifiers, and CO2 equipment.

The included 3-in-1 sensor provides temperature, humidity, and light readings for automated scheduling from day one, with additional device stations available separately as a room's equipment list grows.

Key Features & Benefits

• Modular Device Slots — add device stations as the connected equipment list grows.
• 3-in-1 Sensor Included — reads temperature, humidity, and light out of the box.
• Multi-Equipment Control — manages lights, HVAC, mini splits, dehumidifiers, and CO2 equipment.
• App-Connected Scheduling — programs and monitors the grow room remotely through the TrolMaster app.

Who Should Use the HCS-1 Controller

Single-zone growers who want to start with core environmental control and expand with additional device stations over time are the best fit for the modular HCS-1. It suits a room whose equipment list is expected to grow rather than one that's already fully built out.

About TrolMaster

The HCS-1 anchors TrolMaster's entry point into the Hydro-X controller family, engineered at the company's Sacramento, California headquarters as the base model that the larger HCS-2 and HCS-3 build on. Its modular design is the same philosophy that runs through the rest of the company's device-station accessories.

Frequently Asked Questions

Is the HCS-1 single-zone or multi-zone?

The HCS-1 is a single-zone controller, managing one grow space at a time. Facilities needing multiple independent zones would use one HCS-1 per zone.

What sensor comes with the HCS-1?

A 3-in-1 sensor reading temperature, humidity, and light ships with the controller. No separate sensor purchase is needed to start monitoring.

Can I add more device stations later?

Yes, the modular design lets you add compatible TrolMaster device stations as the setup grows. This includes options like the temperature, humidity, and CO2 stations in the Hydro-X lineup.

Does the HCS-1 control mini split air conditioners?

Yes, with the appropriate remote control station, the HCS-1 can manage compatible mini split units. That station is purchased separately from the base controller.

How do I decide when to upgrade from the HCS-1 to a larger controller?

Once a room's sensor and module count, or its lighting line count, outgrows what the HCS-1 comfortably manages, the HCS-2 or HCS-3 becomes the better fit. Equipment lists that stay modest can run on the HCS-1 indefinitely.
