he versatility of the ACC controller grows even
more powerful with the addition of the all-new,
two-wire decoder system from Hunter. ACC-99D
uses two-wire decoders to control up to 99 stations
without giving up the arsenal of features in the ACC!
The powerful overlapping, stacking array of programs,
along with ACC’s dual programmable Pump/Master
Valve outputs, real-time flow monitoring, and up to four
programmable sensor inputs, take full advantage of this
controller’s high capacity.
Decoder installations are the fastest growing
technology in irrigation control. Why? Because it saves
copper wire, simplifies troubleshooting, permits rapid
addition of new stations, minimizes trenching, and now,
permits remote sensor operation over the two-wire path.
The ACC-99D, Hunter's most powerful controller
teamed with the most versatile decoders in the industry…
an unbeatable combination for large sites with
changing needs.

Decoders, Wiring, and Wire Paths
Each ACC-99D permits operation of 99 stations over one or more two-wire “paths”
to the field. The full line of decoders comes in 1, 2, 4, and 6-station waterproof configurations…each with built-in surge suppression (no external surge suppression
devices required)! You can even add in-line sensor decoders to monitor remote
sensors, via the two-wire paths.
Up to 6 different paths out of the controller may be used to make the most
efficient use of wire, minimize trenching and disruption of landscaping.
Hunter’s color-coded, twisted pair IDWIRE is a cost-effective,
easily-installed, direct burial wiring solution that resists surges and
electrical noise, while providing high tensile strength for permanent
in-ground installation. The wire may also be spliced to follow piping
in complex installations.
Continue adding decoders for
up to 99 stations.
Each decoder has built-in
surge suppression and
grounding wire.
Put Sensors Where They’re
Needed the Most…Remote
Sensors via Two-Wire
Each ACC-99D controller may have
one flow sensor (responding to
station level) and up to four
sensors (with individual programlevel response). Sensors may be
connected in any combination of
direct wire to the controller’s main
module, or remotely, via the sensor
decoder (ICD-SEN).
Each sensor decoder can monitor up to two remote sensors, over
the same two-wire path used for
decoder/solenoid activation (up to
10,000 feet/3 kilometers away). ICDSEN can monitor weather sensors
such as the Mini-Clik®, Rain-Clik™,
Freeze-Clik, Wind-Clik, Mini-Weather
Station, or the HFS Flow Sensor.
Each sensor may have its own
alarm response pre-programmed,
regardless of how it is connected!

Power, Flexibility, Reliability…
In a Package Your Crews Can Already Operate
Hunter’s remarkable ACC-99D decoder output module simplifies decoder
installation and troubleshooting. The ability to operate (and add) large
numbers of irrigation solenoids over a single pair of wires has never been
easier…or more competitive. Best of all, ACC-99D programs like the rest of your
controllers, with simple dial-and-button controls.
Electrically efficient decoders
permit simultaneous operation of
up to 12 solenoids, plus dual Pump/
Master Valve combinations. A full
range of multi-station decoders (1,
2, 4, and 6) features independent

information and easily steps the user through the

way decoder control: each decoder
confirms its on/off commands and status back to the controller, every time it is
activated. This is especially important because ACC-99D can operate dozens of
solenoids, miles or kilometers away. On board diagnostics, overload protection,
current sensing, and line fault detection are all standard, along with our
signature surge suppression circuitry.
Real-Time Flow Sensing: A Landscape Saver
Real time flow sensing will identify a system’s low flow or
overflow conditions instantly, before resulting damage (to
either the system or surrounding landscape) can occur. The
user determines the thresholds for “highest flow rate” and
“lowest flow rate.” When the limits are exceeded, the ACC shuts
off that part of the system. Add the HFS flow sensor and the
corresponding FCT sensor body your piping requires.
