The TrolMaster WD-1 is a dual-function water-presence sensor for Aqua-X and Hydro-X systems, providing both passive leak/flood detection and active irrigation verification. In leak-detection mode, it alerts when water reaches the sensor. In irrigation-verification mode, it is assigned to a specific pump or solenoid output and confirms that water actually reaches the expected location during a scheduled watering event. If the output activates but water is not detected within the configured delay window, the TrolMaster app sends an irrigation-failure alert.
• SKU: WD-1
• Compatible Systems: TrolMaster Aqua-X and Hydro-X
• Maximum Sensors: Up to 25 WD-1 units per controller
• Functions: Leak/flood detection + irrigation delivery verification
• Detection: Water-presence/contact detection
• Irrigation Verification: Confirms water delivery after an assigned pump or solenoid output activates
• Failure Alert: Alerts when the expected water is not detected within the configured delay period
• Leak Alert: Triggers an alert when water contacts the detector in passive mode
• Auto-Fill Support: Two WD-1 sensors can be used with Aqua-X Pro for low- and high-level reservoir detection
• Connection: RJ12 daisy-chain with T-splitter
• Cable Included: 16-ft RJ12 cable
• Interface: LCD with addressing button
• Addressing: Individual sensor addressing through the onboard button
• Water Types: Municipal water, well water and nutrient-enriched water
• RO Water: Very low-TDS RO water may not trigger detection reliably; position the sensor downstream of nutrient injection
• Operating Temperature: 32–122°F (0–50°C)
• Operating Humidity: ≤90% RH
• Package Dimensions: 160 × 86 × 86 mm
• Included: 1× Water Detector, 1× Touch Spot, 1× RJ12 T-Splitter, 1× 16-ft RJ12 Cable, 1× Stab Holder
• Daisy-Chain: Multiple WD-1 sensors can share the existing controller sensor bus
• Zone Assignment: Individual WD-1 sensors can be assigned to specific irrigation outputs
Key Advantage: The WD-1 provides a critical physical confirmation that irrigation water actually arrived, rather than simply confirming that a pump or solenoid was commanded to run. It can also function as a leak detector and, with two units, provide closed-loop reservoir auto-fill on Aqua-X Pro.
