    3.3.3 C ONFIGURING THE RRIGATION ALENDAR Green Field enables scheduling irrigation programs by: Daily calendar • Irrigation by dosing or water • When setting up a schedule, configure the following: Day: X/Y • o X represents the first day that the cycle begins. For example, if you want to define the first day of the cycle as day 4, define X as 4.
  • Page 26 Only If On: Used when there is one switch only. Irrigation continues as long as switch remains on Green Field supports up to 15 extension programs defining which trigger initiates irrigation. In each program, the start and stop trigger must be the same type (meaning both must be dry contact or analog sensor).

  • Page 31 In the example below, between 8:00 – 10:00, the Radiation Sum Limit is 300; between 10:00 – 16:00 the limit is 150. Since during the afternoon hours there is a greater amount of sunlight, the user lowered the limit to ensure that they receive sufficient amounts of irrigation. © Munters AB, 2018...

  • Page 32: Irrigation Based On Vpd Sum

    3.6 Irrigation Based on VPD Sum Green Field enables setting an irrigation trigger based on Vapor Pressure Deficit (kPa•min). The Vapor Pressure Deficit (VPD) is a measurement which incorporates both the relative humidity (RH) and the temperature. When the VPD is high, that means that the RH is low or the temperature is high. Irrigation begins when the VPD reaches the user-defined limit.

  • Page 33: Introduction To The Influence Program

    Several Influences adjust the EC setting. The final adjustment amount is based on the sum total • of the different Influences. You enter up to three points for each Influence setting. Green Field automatically calculates the • curve based on these points.
  • Page 34 Example: As sunlight increases, a crop needs lower EC levels. The following screen illustrates increasing in the EC based on radiation. Since Green Field calculates the decrease in EC proportionally, there will be a 15% decrease when the radiation reaches 600 w/m2.

  • Page 38 Example: A user wants to maintain an EC level of 1.5. To this end, he measures the drainage EC. When the drainage EC falls below 1.5, he increases the EC input. As it rises above 1.5 ms/cm, he decreases the input. © Munters AB, 2018...
