Watermark Electronic Module for Valve Control

WEM Electronic Module For Valve Control | Watermark Soil Moisture Sensors by Irrometer

Overrides irrigation by interrupting the common when soil becomes wetter than the moisture setting.

• The WATERMARK Electronic Module (WEM) is designed to control valves based on soil moisture requirements.
• Adjustable to plant requirements from 10 to 120 Centibars, the WEM uses input from WATERMARK Soil Moisture sensors to control individual valves, valve groups, or all valves.
• Irrigation controllers equipped with WATERMARK Electronic Modules control irrigation based on measured soil moisture, rather than the theoretical assumptions made by a climate based controller.
• The WEM includes a manual override and works with all 24 VAC controllers.
• Also available in a "dry" output version to signal sensor circuits or relays, as version WEM-DC-T.
• Both WEM and WEM DCT include a weather resistant control module and two Watermark #200SS-5 sensors.

WEM Features:

• Makes existing controllers “SMART”
• Can be wired to manage a single valve, a group of valves on a dedicated common, or the entire controller
• Suspends irrigation cycles based on soil moisture status
• Easy to install and use
• 11 position switch for variations in plant demand and soil type
• Requires no seasonal adjustments

WEM Benefits:

• Control your irrigation costs
• Save water, labor, and energy
• Deliver water only when and where necessary
• Grow healthier turf and plants
• Mitigate pest and disease problems
• Reduce fertilizer leaching
• Protect groundwater by minimizing runoff
• No more re-programing controllers for seasonal changes
