The TrolMaster WD-2 water detector can be used to simply monitor the floor or a space for water… as a leak-detector. Or the WC-2 can be used as a water-verification monitor. When used in this way, the water detector is placed where runoff will accumulate (or where water is being introduced to the growing medium). Each output (solenoid or pump) on the Aqua-x can be “assigned” to a specific WD-2. Every time the solenoid or pump assigned to the WD-2 is activated by the Aqua-X, the WD-1 must detect water within a adjustable delay time. If water is not detected (pump or solenoid failure) the Aqua-x will send out a user alert notifying of the “irrigation failure”. Up to 25 WD-1 can be connected to a single Aqua-X.

Use two water detectors (WD-1/2) to activate the new Auto-Fill function on the Aqua-X Pro. One water detector will be positioned at the bottom of the nutrient tank and one at the top of the tank. When the liquid level drops below the bottom sensor, the Aqua-X Pro will activate a solenoid, or pump and the tank will fill back up to the sensor at the top.
