Specifications

The central controller shall permit true random access of all stations in the system and allow area programs to
be constructed with any combination of stations regardless of wiring sequences or satellite designation.
The central controller shall have the ability to manually adjust (percentage increase/decrease) by course, area,
hole or station.
With Optional Weather ET software module, system adjustment factors may be input via actual percentage or
operational ET. The central controller shall have the ability to connect to a weather station. The weather station will
measure and store temperature, relative humidity, dew point, wind speed and direction, and solar radiation for use in
the calculation of evapo-transpiration. The central shall have the ability to automatically calculate and adjust watering
times based on evapo-transpiration. The central controller shall also have the ability to reduce the automatically
calculated runtime by the rainfall measured over the preceding 24 hours. Further, the central controller shall have the
ability to adjust calculated runtimes after they have been scheduled utilizing a Rain Re-Flow alarm response.
The central controller shall include the Turf Guard Soil Sensor software. Individual sensor data can be
assigned to specific sprinklers to allow the user to view current soil moisture on the Watering Plan, allowing the user to
choose to skip watering if moisture levels are above user-defined thresholds, or to activate stations if moisture levels are
below defined thresholds.
The central controller shall employ advanced hydraulic/electrical systems management, allowing the user to
specify hydraulic system design (source and pipes representing mainlines, branches and flow groups) and the hydraulic
limits of each entity. The central controller shall manage system flow by automatically generating the appropriate
station start times based on the hydraulic limits set for each source and pipe, and for the simultaneous station limit set
for each wire path.
The central controller shall display projected flow by source, course, area, program and hole using colors to
differentiate. The graph will calculate and display the maximum instantaneous flow as well as the total volume.
Maximum flow and volume will be displayed in user-selected units. When the Optional Pump integration software is
configured, the actual flow reported by the pump station can be displayed simultaneously with the projected flow for up
to the last 7 days.
The central controller shall have the ability to manually start programs for an entire area or for an individual
hole/area. Manual programs may be started in normal program time or a manually selected time. The central
controller shall have the ability to start a multi-manual cycle on a wire path, running up to 100 stations simultaneously
with a run time of up to 99 minutes.
The central controller shall have the ability to independently suspend (hold) the automatic operation of an
individual station or course. The station hold duration shall be programmable for the current irrigation day up to 30
days, or may be permanent.
The central controller shall have the ability to control non-irrigation devices through switch outputs. Each
switch (up to 50) will have an independent seven-day calendar schedule and start times for up to 24 starts. Switch
outputs may run from one minute to 23 hours and 59 minutes (programmable in one-minute increments), with
individual start times for each station (switch output). Switches may also be scheduled to run with any program and
include the ability to offset the start time prior to or after the start of the program.
The central controller shall allow a user-defined response to a Gate Way alarm for pump pressure or rainfall
and allow a user-defined response to a weather station rainfall threshold.
The central controller shall offer a Weather ET software option for configuring weather alarms for Rainfall
Rain Re-Flow alarm response, Wind Speed, Temperature, Wind Direction, Solar Radiation, Relative Humidity, Dewpoint.
