  • Page 6: Leit Rc2Et Handset Features

    LEIT RC2ET Features The LEIT RC2ET remote control handset is used to communicate with LEIT- 2ET weather based, wireless irrigation controllers. The user can program the handset with daily scheduled irrigation programs and detailed information on the site zone, such as; planting, soil type, planting type, plants density, percentage of slope, microclimate, irrigation method, irrigation efficiency, flow rate and spacing used. This information is downloaded to the LEIT-2ET controller, which uses it to determine the plants water loss and the total irrigation rate per day needed. With this information along with other factors, including depth of irrigation, allowable depletion and basic intake rate, the LEIT-2ET controller calculates system or zone run time with number of cycles per day. This calculated run time replaces or overrides the program duration that the user set originally. The controller performs the daily calculations needed at midnight to override or adjust the scheduled irrigation program specifically for each zone, to compensate for evapotranspiration (ET). This information can be reviewed in the Report Menu. • ET setting can be input to each valve when ET Setup is changed to active • Sensitivity of the ET setting can be optimized using the editing feature without changing any of the ET settings • Wind Stop setting can be programmed to shut off the system at wind speed from eight (8) to twenty-five (25) miles per hour (12.9-40 Km/h) • The Rain Off feature can be accessed either via the weather station in a range of 1/8” to 1” (3 mm to 25 mm), or via a rain sensor • ET features can be overridden at any time • Report Menu screen provides various function information on the controller operation and program. Current Status report provides controller time and date, station open or short circuit, controller power level, any feature or device activity, alerts, if ET is active, sensor(s) information and the average for 24 hour ET. Program Status report provides controller program changes made along with the handset ID that made the changes. History report provides total run time, total rain amount, and ET saved in both time and percent, for the last two (2) months...

  • Page 33: About The Leit Rc2Et Environment Features (Leit-2Et Only)

    About the LEIT RC2ET Environment Features Introduction Today, irrigation use can be optimized through the use of our weather based irrigation control system developed for landscape irrigation. This can be achieved by monitoring the soil, temperature, humidity, radiation, rainfall, wind, and environmental conditions at the irrigation site. Both the plants water requirements and the amount available to the plant roots can be measured or estimated through a variety of techniques. These techniques include the feel method, which is an estimate based on the user’s knowledge of the irrigation site, the more accurate method of utilizing tensiometers, or the use of weather sensors designed to monitor real time conditions including water demands influenced by the local environment, the irrigation method and the plant types. Water Requirements To simplify the relationships between plants, water requirements and the environment, the term evapotranspiration is often used. Originally established for agriculture, where irrigation requirements are well documented, evapotranspiration measures the loss of water for various crops planted by farmers. Evapotranspiration takes into consideration the loss of water from the plant surface, the evaporation of water from the soil and the water lost through transpiration during a specific time period. Historical values for many crop types have been recorded and are made available through agricultural extension services. Evapotranspiration (ET) Several methods have been developed to estimate crop ET. Most methods use weather data to provide an estimate of reference, or potential, evapotranspiration (ETo). Often this estimate of reference is converted to “actual” ET using a factor known as a crop coefficient (Kc). In landscape irrigation, reference evapotranspiration (ETo) is established for well-watered turf grass, however most landscape species do not have values established. The turf and landscape industry’s managers and users are not equipped to measure the plants’ water loss. The feel method is not practical due to the large variety of...
  • Page 34 BASED ON reference crop Radiation well watered Temperature grass Wind speed Humidity K c factor well watered crop optimal agronomic conditions Water Saving Knowledge of the environment, plants water requirements, and the tools to calculate how much water is available in the soil may help in reducing water use by increasing irrigation efficiency. By viewing the soil as a reservoir for the plant’s water, and calculating the daily water needs of the plant using various factors and landscape coefficients, we can determine approximately how long plants can survive on the water available in the soil. When the water in the soil is close to depletion, a timed irrigation in the proper amount can refill the soil profile, restarting the cycle.
  • Page 35 The Importance of Soil Texture in Setting ET Before programming the LEIT RC2-ET handset and using the new ET features we recommend that the user read about soil texture. Knowing the soil type is important in setting the proper configuration on the LEIT RC2-ET. Most users can determine the soil type by reviewing the following: A fine-textured soil is referred to as clay soil. Sandy soil is a coarse-textured soil. Numerous soil properties are influenced by texture, including drainage, water- holding capacity, aeration, susceptibility to erosion and organic matter content. The soil texture determines the rate at which water drains through saturated soil. Water moves more freely through sandy soils than it does through clay soils. Once field capacity is reached, soil texture also influences how much water is available to the plants. Clay soils have a greater water-holding capacity than sandy soils. In addition, well-drained soils typically have good soil aeration meaning that the soil contains air that is similar to atmospheric air, which is conducive to healthy root growth, and thus, to healthy plants. How to Determine Soil Texture and Type • Sandy soil: Feels gritty and if formed into a ball when moist, falls apart easily. • Loamy soil: Feels somewhat gritty, retains water easily and is easy to work with it. It has relatively even amounts of sand, silt, and clay. If formed into a ball when moist, will hold its shape, yet still will break apart easily when squeezed. • Clay soil: Forms large, hard clods, and cracks form on the surface. Clay soils feel sticky and are bendable when moist. A ribbon can be formed when moist by pinching soil between fingers and thumb. A longer ribbon formed before it breaks indicates a higher amount of clay.
  • Page 36 About the LEIT RC2-ET Environment Features (LEIT-2ET only) The ENVIRONMENT menu is used to activate and set the ET feature, adjust budgets, and set wind and rain gauge sensors. The ET MONITOR screens are used to input site information for each zone which is then downloaded to the LEIT-2ET controller. With the ET data received from the weather station the LEIT-2ET controller calculates the hourly and daily local microclimate and adjusts or overrides the daily scheduled irrigation program. ET Edit can be used to edit ET settings from 10% to 200%. The Budget feature is used to reflect seasonal changes by adjusting each month’s irrigation schedule by percentages from 10% to 200%. The Rain Gauge setting is used to select rainfall amounts from 1/8” to 1” (3 mm to 25 mm). This data, coupled with information provided by the weather station, will adjust or override the irrigation program. Wind Speed information provided by the weather station overrides irrigation when wind speeds ranging from 8 to 25 MPH (3.5 - 11.1 m/s) are reached. How DIG’s Weather Based System Works As daily ET accumulates, ET value, along with site information and microclimate coefficients are used to determine plant water requirements and allowable soil depletion rate. System run time is set and based upon the irrigation method along with application rate and site information water requirements. When ET is active, this calculated run time replaces or overrides the program duration that the user set originally. In activating ET the user enters detailed information on each site zone to the LEIT RC2ET handset. This information includes mature or new planting, soil type, plant type, plant density, slope, microclimate type, irrigation method, irrigation efficiency, flow rate and spacing if available. Based on the user input and the information collected hourly from the weather station sensors, the controller performs the daily calculations needed to override or adjust the scheduled irrigation program specifically for each zone, to compensate for...

NOTE: The controller can receive information from more than one weather station in the area if available. How to Program and Activate ET 1. Setting and Activating ET: Using the ET MONITOR feature in the ENVIRONMENT screen, the user can enter detailed site information to each zone (valve #) and download this information to the LEIT-2ET controller. The controller use the information received from the handset and the weather station to adjust the daily irrigation schedule. The effect on the daily scheduled irrigation programs based on weather data collected can be reviewed in the REPORTS MENU and HISTORY Report. Activating ET: Using this feature the user enters detailed information for each valve or site zone. Follow theses steps to configure each zone setting conditions using the handset ET MONITOR screens: Step 1: Select plant stage of life (example: mature) Step 2: Select soil type (example: clay) Step 3: Select plant type (example: mix planting) Step 4: Select plant density (example: 50-70%) Step 5: Select percentage of slope (example: 0 to 4%) Step 6: Select microclimate type (example: open space) Step 7: Select irrigation method (example: spray) Step 8: Select irrigation efficiency (example: 70%). This is the default setting that can be changed. Step 9: Select irrigation method flow rates (example: 1 GPM (3.8 L/M) Step 10: Select irrigation method spacing (example: 10’ (3 m)

If they are set of lower coverage, the Flow Rate must be adjusted upwards to the weighted average to compensate. For example: If 6 rotors are installed in a rectangular pattern with 4 operating with 90° coverage and 2 operating with 180° coverage, the Flow Rate (FR) that should be entered should be: ((FR90*4)*4 + (FR180*2)*2) / 6 = (20/6)*FR = 3.3 * FR Where FR90 and FR180 are the flow rates of the 90° rotors and 180° rotors repectively. NOTE: In the event an audit of the site soil condition cannot be performed prior to initial setting of the LEIT ET System, we recommend soaking the soil thoroughly to ensure the soil is wet as a reference point for the system from which the LEIT-2ET starts calculating the site ET. FINE-TUNING THE SYSTEM: We recommend monitoring both the plant health and the soil moisture level on a weekly basis. If the plants are showing signs of distress or the soil appears to be oversaturated, fine-tuning of the system can be accomplished utilizing the ET Edit feature. The system can be fine-tuned based on weather pattern, location and the ET zone setting. Either an upward or downward adjustment in percent can be made to adjust to the actual ET setting condition. Again, DIG strongly recommends a careful monitoring of the site for the first month of operation.
