The Wireless Multiple Hydrozone System (W-MHS) is typically used in large residential and commercial applications where extensive wire trenching is a concern. The system provides soil moisture automation for 24 VAC irrigation controllers by eliminating programmed irrigations when plants have adequate soil moisture — saving water, energy and money and growing healthier turf and plants. It makes decisions to open or close the valve common wire or signals the controller based on plant demand at the root zone verses a timed schedule or weather data. The system will control up to 48 stations/valves in up to eight moisture groups. The W-MHS comes standard in a lockable stainless-steel enclosure with state-of-the-art digital electronics. The W-MHS will automatically report watering history, irrigation water savings and will indicate the last allowed watering. Receive reports and download data from the system for maximum irrigation management and analysis.
