FCC Notice

FCC ID: M3UICDDEC

This device complies with FCC rules Part 15. Operation is subject to the following two conditions:

• This device may not cause harmful interference and

• This device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for class B digital devices, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation.

This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment on and off, the user is encouraged to try to
correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and the receiver

• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected

• Consult the dealer or an experienced radio/TV technician for help

The user is cautioned that changes and modification made to the equipment without the approval of the manufacturer
could void the user’s authority to operate this equipment.

Installation In str uc t ion s

This package includes:
(1) ICD400 or ICD600 decoder module

(1) Instruction Sheet

The ICD Series decoders may be connected to the Hunter ACC, AGC, Genesis, VSX, and IDS decoder controllers.

• In the ACC or AGC controllers, each decoder is programmed with station address(es) at the controller,
before installing it in the 2-wire path. These controllers have a programming port on the decoder output module.
Program the station number(s) into the decoder, and then write the station number assignments on the metallic tag
on the decoder. The 8-digit serial number is not used in the decoder set-up on these controllers.

• ICD Decoders may also be programmed with the Hunter Industries Model ICD-HP handheld programmer,
after installation.

1. In the ACC/AGC series of controllers, first Insert the red and blue wires from the decoder into the Programming Ports on
the decoder output module (ADM99).

2. Use the procedure in the ACC / AGC owner’s manual for addressing decoders. Use a ballpoint pen to write the station
number(s) on the decoder’s metallic tag.

Each decoder output can power two standard 24VAC Hunter solenoids. They must be wired in parallel, as shown in step 9.

• In Genesis, VSX, and IDS controllers, the deco der can be installed on the 2-wire path before giving it a station

address using the 7-digit serial number followed by “x”. The 8-digit serial number is required

• “x” at the end of a serial number is replaced with 1, 2, 3,

or 4 in the controller station programming to indicate
which colored pair matches the station number (see
chart).

• Note and record the 8-digit serial number on the decoder

body, and then use the controller keypad to indicate
which station number(s) will be assigned to the decoder
(see controller manual).

Installing the decoder:

1. Controller power must be OFF when installing decoders in
the 2-wire path.

2. Select the decoder location (unless you are replacing an
existing decoder). Decoders should be within 100 feet/33m of
the solenoids they will operate. Decoders are waterproof, but
should be installed in a valve box to facilitate future service
and increase longevity.

3. Locate the 2-Wire path. These are the Red and Blue wires coming from the
controller. The wire path must be cut to insert decoder wiring,
unless you are replacing an existing decoder.

Be sure to leave enough slack in the wire path to allow easy
connection of the decoder, and to allow for contraction of wiring
due to temperature changes. Hunter recommends at least
5ft./1.5m slack for each decoder, to allow it to be removed from
the valve box completely for installation, service, and inspection.

4. Identify the color-coded wires on the decoder. The red & blue
wires connect to the red and blue wire path from the controller.

5. Strip the cut red and blue wire ends back approximately ½ inch
(12mm).

6. Twist the stripped red wire ends (the ends from the 2-wire path
and the decoder) together, and thread securely into the wire nut
for the DBRY-6 or equivalent waterproof connector. Seal in
accordance with the connector manufacturer’s instructions (insert threaded wire nut connection into waterproof grease,
and snap cap securely shut over wires).

7. Repeat with the blue wires: connect the blue end(s) from
the 2-wire path with the decoder, and secure in a
separate DBRY-6 or equivalent waterproof connector.

8. Each color-coded decoder output operates one or two

solenoid

connections

solenoids up to 150 feet/45m away (greater distances
are possible, but increase susceptibility to lightning
damage).

• Wire runs to the solenoids should be twisted pairs (if

solenoids are over 20 ft./7m from decoder) of at
least 18 AWG (1mm dia.) wire. The twist in the wire
is important, because it is an aid in lightning and
surge suppression.

Connect each color-coded station output to the desired solenoid(s) as follows:

• The non-insulated bare copper wire is the decoder’s grounding wire and is only used on selected decoders. If the

plan does not specify otherwise, ground at least every 12

th

decoder
module in each two-wire path, OR every 1000 ft/330m of wire, whichever
is first.

9. Strip back and connect the two black wires from the decoder to the solenoid
leads for the first station. Insert and seal connections with DBY or equivalent
waterproof connectors.
Note: Each ICD output may operate two solenoids simultaneously. The
solenoids must be connected in parallel, rather than in series. Each decoder
