Irrigation Controllers
ET2000e
The Calsense ET2000e Irrigation Controller is an important water conservation and management tool.
Some of its major water management features include flow monitoring, moisture-based irrigation, and
the use of daily evapotranspiration (ET) to automatically calculate station run times. The ET2000e
provides a wide range of programming flexibility, including:
• Seven programs, which can be programmed to water individually or interspersed to maximize
system capacity and reduce watering time
• Cycle and soak scheduling to water each station for a fixed cycle time and allow the water to
soak in between cycles, maximizing infiltration and minimizing runoff
• 7-day, 14-day, 21-day, or 28-day watering schedule
• 12-month master schedule to pre-program an irrigation schedule for an entire year, saving the
trouble and expense of changing the schedule every month
• Moisture-based irrigation, which allows the controller to stop irrigation when the soil reaches a
preset moisture content; requires Soil Moisture Sensor (model 1000-S), purchased separately
• Manual programs, which allow the user to schedule stations to run for a preset time, up to 6
times per day, for hydro-seeding and new planting
• Water-use budget, which continually compares actual usage to a user budget. If the usage
exceeds the allowed budget, the controller notifies the user with an over-budget message.
• Electrical alerts, such as short circuits and no currents, to help the user troubleshoot field wiring
and solenoid problems
• On-screen context-sensitive help provides programming instructions and tips from any screen on
the controller
• Permanent memory stores all controller programming and setup data, including date and time,
in non-erasable memory
• Available in multiple station counts including 6, 8, 12, 16, 24, 32, 40, or 48 stations. If less than
48 stations are purchased initially, additional stations can be added at any time.
Flow Monitoring
The ET2000e Irrigation Controller works with the Calsense Flow Meter (model FM) to continuously
monitor real-time flow through the irrigation mainline, 24 hours a day. This feature detects and alerts the
user to mainline breaks, high flows caused by broken risers and pipes on each individual station, and low
flows due to malfunctioning or shut down valves.
Since the ET2000e Irrigation Controller uses real-time flow measuring, it monitors and maintains a record
of all water usage. Scheduled irrigation usage is recorded on a station-by-station basis and on a total
controller basis for the current month and the previous month. Unscheduled water usage, along with
non-controller water usage, is recorded and shown using built-in reports. Examples of the non-controller
usage include use of quick-couplers or manually bleeding of valves.
