Trolmaster Aqua-X Plus Controller with AMP-3 Sensor Board, Free Phone App

TrolMaster Aqua-X Plus Multi-Zone Controller with AMP-3 Sensor Board

The Aqua-X Plus is the NFS-3 head unit of TrolMaster's irrigation line, a multi-zone controller that runs pumps, valves and sensors from one screen. The bundled AMP-3 sensor board carries a BNC port for a pH probe and a Mini DIN port for an EC and temperature probe. Readings show on the board's own small display and on the controller. The 7 in, 800 x 480 touchscreen handles setup, schedules and history without a laptop. One controller addresses up to 240 devices and 25 sensors, covering pH, EC, water temperature and substrate moisture, EC and temperature. Modules daisy-chain on standard RJ12 cable, with up to 1,000 ft between the controller and the farthest device. A CAT5 cable puts the unit straight on the internet, and TrolMaster's free app mirrors the screen on your phone. Alarms push to that phone when a reading crosses a setpoint. Input power covers 100–240 VAC through the included adapter, so the unit drops into domestic or export rooms. Multiple Pump Link lets different pumps feed different valve groups, which matters once a room splits into veg and flower zones.

An Irrigation Control System That Steers by Substrate Water Content

Crop steering is where this unit earns its wall space. Pair it with WCS-1 or WCS-2 water content sensors and it can trigger irrigation from substrate moisture rather than a fixed clock. Growers in coco or rockwool typically set an overnight dryback target, then let the controller stack small shots after lights-on until blocks reach field capacity. The history graphs show how fast each zone dries back, so generative and vegetative steering become numbers instead of guesses. Mount the screen outside the canopy near the irrigation manifold, with the sensor board close to the reservoir where the probes live. The controller carries an IP20 rating, so keep it clear of spray and away from the hose-down zone. Probes, water content sensors, pumps and valve modules are separate pieces, so plan for the ones you want running on day one. Programs save and copy to micro-SD, which makes cloning a setup onto a second room quick. Expect a learning curve the first week. Once zones, pump links and alarm limits are set, the daily work comes down to reading graphs and nudging shot sizes.

Key Features

• 7 in Touchscreen: A full-colour LCD puts schedules, zones and history graphs on the wall where the irrigation crew works.
• AMP-3 Sensor Board Included: The board takes a pH probe and an EC and temperature probe, then shows those readings locally and on the controller.
• Crop Steering Function: WCS-1 and WCS-2 sensors let substrate water content start and stop irrigation cycles on their own.
• 240-Device Capacity: Pumps, valves and sensors chain on RJ12 cable, so the system grows room by room without a new head unit.
• CAT5 Internet and Free App: A wired network link feeds the TrolMaster app for live readings and remote changes from your phone.
• Alarm Notifications: Setpoint alerts reach your phone when pH, EC or moisture drift outside the limits you set.
• Multiple Pump Link: Different pumps can serve different valve groups, which keeps feed lines separate between rooms or stages.
• Micro-SD Data Transfer: Settings and logged data save, copy and import, so a proven program moves to another controller quickly.
