Background
The revolutionary CS3500 will change the way you
think about sprinkler controllers forever! Nearly
all controllers have traditionally relied on a
timer, or clock. Though convenient, clock-based
controllers have some serious drawbacks. Since the
amount of water that landscaping plants and turf
require varies continuously through the growing
season, the clock settings should be constantly
updated. In many cases, the timer is set for the
hottest part of the growing season and never
changed. This leads to massive overwatering during
most of the year.
The CS3500 overcomes the problem of chronic over
watering through the use of a revolutionary moisture
sensor, the Acclima Digital TDT™ Moisture Sensor.
Instead of controlling the sprinkler system with a
clock, the CS3500 is controlled by the actual
moisture level in the root zone.
The Sensor
The Acclima Digital TDT™ Moisture Sensor
represents a revolutionary advance in the irrigation
industry. It is the first moisture sensor to
incorporate the accuracy of digitized Time Domain
Reflectometry in a low-cost instrument, providing
highly accurate absolute readings of soil moisture
under all conditions of temperature and soil
chemistry under which turf will grow. No other
sensor on the market matches its accuracy and
stability. Independent test data from the Center for
Irrigation Technologies verifies this extraordinary
claim and is available upon request.
The sensor acts like an in-ground, closed-loop
evapo-transpiration (ET) weather station. All
environmental variables, including wind,
temperature, precipitation, humidity, soil type, and
plant growth are integrated into the output of the
moisture sensor.
Water Savings
Installing an Acclima Precision Irrigation System
will result in water savings of between 30% and up
to 50%. Some of our customers have experienced
payback periods as short as 3.8 months! And with the
patented Acclima system, your landscaping will look
great. Many of our customers report that their
properties have never looked better.
No Hassle Operation
Tired of resetting your clocks for different
climatic conditions? With the Acclima Precision
Irrigation System, you can forget about the clock.
Once the moisture levels are set, the system
self-corrects for changes in conditions. During the
hottest part of the year, the system might water
every day. Then when the temperature cools, or you
get a big rainstorm, the system will hold off
watering until the moisture level in the ground
falls below the threshold you have set.
Flexibility
Each zone can be set to one of three modes of
operation: as a master zone with its own sensor, as
a slave zone that tracks a master zone, or as a
timed zone. The CS3500 easily accommodates both drip
zones and spray zones. So no matter how complicated
your system, the CS3500 can keep up.
Easy Installation
The patented Acclima 2-wire system makes
installation of both new systems and retrofits a
snap. No re-wiring is needed, and the CS3500 system
is compatible with all 24V AC solenoids.
Features:
- Large graphic display with text prompting
simplifies programming and operation.
- Optional sensor-mode operation saves water
and automatically adjusts to weather patterns.
- Non-volatile program memory maintains
configuration information even if the power
fails and the batteries are dead.
- Sophisticated central control capabilities
using Acclima Irrigation Manger™ Software.
- Advanced Communications capabilities through
serial cable, dial-in modem, or radio
communications.
- 2-wire system adds flexibility and ease
requiring much less wire than conventional
system wiring.
- Sophisticated calendar/clock automatically
compensates for leap years and optionally for
daylight saving time.
- Clock can be maintained for up to 10 years
without power using a CR2032 battery.
- Water on Demand efficient irrigation
capabilities. The controller only waters when
the soil needs moisture and will only apply the
water needed.
- Supports up to 10 soil moisture sensors with
sensor sharing so multiple zones can be
controlled by a single sensor.
- Each soil moisture sensor added to the
system also adds a sensor program to the system
with 6 start times each (up to 40 programs are
possible in total).
- Flow meter support monitors for broken
pipes.
- Multi-zone watering up to 4 zones at a time
maximum.
- Multi-zone watering may be configured on a
per-zone based on the water usage of that zone
versus available water. (Drips might run 4 zones
at a time, while large zones run one or two at a
time). This configuration can happen
automatically when a flow meter is attached to
the system, or can be adjusted manually at any
time.
- Cycle + Soak feature prevents runoff by
putting down the water in short bursts. Cycle +
Soak is configurable independently for each
zone. While one zone is soaking, others will
water, maximizing water output for the
irrigation time allowed.
- Programmable valve delay allows slow-closing
valves time to turn off completely.
- Valve current testing enables easy
maintenance of solenoid valves.
- Manual program operates each zone for a
programmable amount of time for inspecting
sprinkler heads after mowing the lawn.
- Pause mode allows suspending controller
operation for a period of time, after which
irrigation will resume automatically from where
it left off.
- Up to 6 programmable pause events allow
scheduling of lawn parties in advance. Pause
events may be scheduled to any future date and
time, and will automatically pause the
controller for a programmable time period.
- Sophisticated restriction capabilities
allowing for complex water schedules.
- Controller resumes where it left off after
power failure.
- Water Budget is programmable between 2-500%
per month. Water budget does not apply to sensor
programs, as sensors adjust for seasonal changes
automatically.
- 64 Zones, run-time can be set from 0 to 18
hours in 1-minute increments
- Zones may be quickly disabled without
loosing other configuration information.
- Manual zone start and manual program start
- Status reporting lists history of errors
that may have occurred on the system
- Operational status report shows current
zones watering, and all zones waiting to water.
- Durable, plastic box is easy to mount and is
weather resistant for outdoor installation.
- Adaptable to the TRC Commander radio though
a separate adapter.
