  1. Closed-Loop Irrigation Control Sensor-Based Precision Irrigation system by Acclima Water conservation By Acclima

  2. Conventional Clock-Based Irrigation Control Manual ProgramEntry Timer Program Execution Occasional Manual Correction Prompted by Stress or Saturation Open Loop: No Automatic Feedback to Control Moisture Level Water conservation By Acclima

  3. Evapo-Transpiration-Based Irrigation Control Complex Parametric Input with Regular Adjustment Weather Station, Computer and Communications Means ET Enabled Clock Open Loop: No Automatic Feedback to Control Moisture Level Water conservation By Acclima

  4. Soil Moisture-Based Irrigation Control One-Time Moisture Threshold Inputs Feedback-Enabled Automatic Controller Closed Loop: Automatic Feedback Maintains Proper Root Zone Moisture Water conservation By Acclima

  5. Instability – The #1 Problem Temperature Non-Digital TDT Moisture Sensors Water Content Electrical Conductivity Sensor Output is a Complex Function of all Three Input Variables Water conservation By Acclima

  6. XTra Sensor Stability -- Temperature Less Than 1% Deviation 25 Reading in % Water 20 1 Temperature in Degrees Celsius 50 Water conservation By Acclima

  7. XTra Sensor Stability – Electrical Conductivity Less Than 1% Deviation 25 Reading in % Water 20 0 2.5 In-Soil EC in dS/m Water conservation By Acclima

  8. Saturation Area: Heavy Nutrient and Water Loss Root Putrefaction Field Capacity: Very Small Percolation Loss Increasing Water Content Allowable Depletion Limit Permanent Wilt Point: (dead grass) Water conservation By Acclima

  9. Installing the Sensor – Techniques • Install in representative area for the zone • Avoid depressions • Avoid high-traffic areas • Avoid large rocks, tree roots • Install in healthy turf • Remove a 60cm square turf plug • Install sensor 10cm deep • Re-compact soil around rods to original compaction • Replace turf plug and seal around edges • Connect wires in a nearby value box Water conservation By Acclima

  10. Advantages – Water Savings • System Monitors ET in the Root Zone and Applies Just the Right Amount of Water to Hold Moisture in the Target Range • All Weather, Soil and Plant Characteristics are taken into Accurate Account in the Measurements • Upwards of 40% Water Savings can be Expected over a Well-Managed Controller Based System Water conservation By Acclima

  11. Advantages – Maintenance Savings • Seasonal Clock Adjustments are Eliminated • System Automatically Accommodates Heavy Rains, Cool Periods, Hot Periods, Dry Winds without Need of Adjustment. • Initial Settings Remain Stable Year after Year Water conservation By Acclima

  12. Advantages – Environmental Issues • Ground Water Contamination with Pesticides and Fertilizers is the Result of Over-Watering Crops and Turf. • Enormous Reductions in Fertilizer and Pesticide Applications are Possible with Precision Irrigation. Eastern Oregon Onion Fields show 50% Reduction. Water conservation By Acclima

  13. Advantages – Healthier Landscape • Over-Watering Drives Oxygen out of the Soil and Putrefies Roots • Over-Watering Leaches Nutrients and Pesticides from the Soil • Over-Watering Develops Fungi in the Soil • Over-Watering Weakens Drought Tolerance and Reinforces Over-Watering • Under-Watering Stresses Lawns and Promotes Weed Growth Water conservation By Acclima

  14. 8701 – EZ Pro Xtra • Simple retro-fit design • Single Sensor • Works with existing controller • Converts any 24V controller to Sensor-based System • Easy Installation Water conservation By Acclima

  15. 8710 – EZ Pro Max • Central Control System • Water on Demand • 64-Zone capacity • Run up to 16 sensors • Buit-in modem • Remote Control Access • 2 Wire Connectivity • Friendly Software Water conservation By Acclima

  16. 1 valve 1 valve 4 valves 2 valves Communicating with other Devices 2-wire bus 2 valves Water conservation By Acclima

  17. 2-Wire System Specifications • Maximum distance for controller to any device: 1300m • Maximum total paired wire load (unsheathed): 3300m • Maximum total paired wire load (sheathed): 4950m Water conservation By Acclima

  18. CSU Site Performance 8/1 to 9/16 (2004) Water conservation By Acclima

  19. Clark County School District 2003 (Acclima) vs 2002 (ET) Water conservation By Acclima
