Hydro-X Plus Controller with 4-in-1 Sensor

Step Up to a 7-Inch Touchscreen With Dual Lighting Lines

The TrolMaster HCS-3 Hydro-X Plus controller builds on the entry-level HCS-1 with a 7 inch touchscreen display and support for up to 256 lights across dual lighting lines, giving larger single-zone rooms more direct, on-device control than the base model offers. That dual-line lighting capacity is the main reason growers step up to this tier.

The included 4-in-1 sensor adds CO2 readings to the standard temperature, humidity, and light measurements, and the controller can also monitor for smoke and water leaks alongside its normal equipment management duties.

Key Features & Benefits

• 7-Inch Touchscreen — is a larger on-device display for direct scheduling and monitoring.
• Dual Lighting Lines — supports up to 256 lights split across two independently dimmed lines.
• 4-in-1 Sensor Included — adds CO2 monitoring alongside temperature, humidity, and light.
• Smoke and Water Detection — provides built-in alerts for smoke and water leak conditions.

Who Should Use the HCS-3 Plus Controller

Growers running larger single-zone lighting setups who want a bigger on-device touchscreen and built-in CO2 sensing will get the most benefit from stepping up to the HCS-3. It's a middle tier between the entry-level HCS-1 and the browser-accessible HCS-2.

About TrolMaster

The HCS-3 fills the middle of TrolMaster's Hydro-X controller lineup, engineered at the company's Sacramento, California facility to give larger lighting setups more on-device capability without stepping all the way up to the browser-connected flagship model. It shares the same modular device-station approach as the rest of the Hydro-X family.

Frequently Asked Questions

How many lights can the HCS-3 support?

Up to 256 lights, split across two independently dimmed lighting lines. That's a meaningfully larger capacity than the entry-level HCS-1 offers.

What does the 4-in-1 sensor measure?

Temperature, humidity, light, and CO2. This adds CO2 monitoring beyond the 3-in-1 sensor bundled with the entry-level model.

Does the HCS-3 detect water leaks?

Yes, it includes smoke and water leak detection alerts in addition to standard climate control. Those alerts run alongside its normal equipment scheduling.

Is the HCS-3 single-zone or multi-zone?

The HCS-3 is a single-zone controller, like the rest of the HCS lineup. It carries expanded lighting and sensor capacity compared to the entry-level model.
