Controller Installation
Installing the Cabinet
1. For safe and reliable operation, select an installation
site which can ideally provide the following conditions:
• For Indoor model controllers – Inside a garage or
other structure which will provide protection from the
weather.
• For outdoor model controllers – Protection from
irrigation spray, wind and snow. A shaded location is
recommended.
• Access to a grounded AC power source (within 4'
[1.2m] for indoor models) which is not controlled
by a light switch or utilized by a high current load
appliance, such as a refrigerator or air conditioner.
• Access to the sprinkler control valve wiring and
optional accessory wiring.
2. Drive a wood screw (provided) into the wall at eye level.
Leave the screw extended approximately 1⁄4" (6mm)
from the wall. See Figure 1.
Note: If installing the controller on drywall or masonry,
install screw anchors.
3. Remove the lower cabinet access cover by pressing it
on the bottom and pulling it directly outward from the
cabinet.
4. Hang the cabinet on the screw using the keyhole slot
on the back panel. Make sure the cabinet slides down
securely on the screw.
5. Install the lower mounting screw and tighten securely.
Note: Conduit and adapters are not provided. Install
conduit as required by local electrical codes.
6. Remove the power wire access cover. Remove the
conduit knockout according to the size of conduit being
used. Install 1⁄2" (13mm) conduit for power/equipment
ground wires (outdoor models only) and 3⁄4" (19mm) or
1" (26mm) conduit for valve wires (all models).
Figure 1

5
Installing the Valves
CAUTION: Maximum screw torque not to exceed 5 inlbs.
1. Route the valve wires or wire cable from the valves, into
the controller cabinet.
Note: 18AWG (1.0mm2) multiwire sprinkler valve
connection cable can be used. This cable is insulated for
direct burial and is colorcoded to simplify installation.
It can be routed directly into the controller through the
access hole provided for valve wire conduit (if conduit is
not used).
2. Attach the white colorcoded wire from the cable to one
wire from each valve solenoid. (Either solenoid wire can
be used for this connection.) This is called the “Valve
Common” wire. See Figure 2.
3. Attach a separate cable wire to the remaining wire from
each valve solenoid. Note the wire color code used
for each valve and the watering station it controls. You
will need to have this information when connecting the
valve wires to the controller.
4. Secure all wire splices using wire nut connectors. To
prevent corrosion and possible short circuits, always
use an insulated wire nut, grease cap or similar
waterproong method.
5. At the controller end of the valve connection cable,
strip back 1⁄4" (6mm) of insulation from all cable wires
6. Secure the Valve Common wire to the terminal labeled
COM. Connect the individual valve wires to the
appropriate station terminals. Connect the master valve
wire (if applicable) to the terminal labeled MV.
Note: Connecting a master valve or pump start relay
is optional and may not be required for your sprinkler
system.
Installing a Pump Start Relay
CAUTION: To prevent controller damage, ensure the pump
start relay current draw does not exceed 0.4A. Do not
connect the pump motor starter directly to the controller.
1. Connect a wire pair to the 24VAC pump start relay.
Route the wires into the controller housing with the
valve wires.
2. Connect one wire to the terminal labeled COM .
Connect the remaining wire to the terminal labeled MV.
See Figure 2.
CAUTION: To prevent pump damage due to “Dead
heading,” connect a jumper wire from any unused station
terminal to a station terminal with a valve connected.

Installing a Rain Sensor (optional)
A rain sensor can be connected directly to the KD2 to
automatically interrupt watering when it begins to rain.
When the rain sensor absorbs rain water, it automatically
signals the KD2 to suspend all watering operations. The
display will alternately show SEN (sensor) and the time of
day until the rain sensor drys out and resets the controller
for automatic operation.
1. Route the wire cable from the rain switch sensor into
the controller along with the valve wires.
2. Remove the jumper wire from the sensor terminals.
3. Referring to the instructions provided with the rain
sensor, connect two wires from the rain sensor
designated for “Normally Closed” applications to the
sensor terminals. See Figure 3.
4. Once powered, turn the dial to Special Functions.
Press and scroll to RS Y (Rain Sensor Yes).
Press / to set sensor to RS Y (active) or RS N
(Bypass).
Note: The default setting is RS Y (active).
Connecting the Power Source
WARNING
AC power wiring must be installed and connected by
qualied personnel only. All electrical components and
installation procedures must comply with all applicable
local and national electrical codes. Some codes may
require a means of disconnection from the AC power
source installed in the xed wiring and having a contact
separation of at least 0.120” (3mm) in the line and
neutral poles. Make sure the power source is OFF prior
to connecting the controller.
1. Verify that the power is turned o at the source.
2. Remove the power connection access cover.
3. Route the power and equipment ground wires from the
power source through conduit into the controller power
connection compartment. For wire restraint, route the
cable inside the compartment as shown in Figure 4 A.
Note: The international model terminal block accepts
wire size up to 4 mm
2
.
4. For nonUS models, use the terminal block which
accepts wire size up to 4 mm
2
(Brown for line, Blue for
neutral and Green for earth ground). For US models,
use the wire nuts provided, secure Line to the Black
wire, Neutral to the White wire and Equipment Ground
to the Green wire. See Figure 4 B and C.
5. Install and secure the power wire access cover.

Planning Your Watering Schedule
It is often helpful to plan your watering schedule on paper
before beginning the programming steps. The information
can then be transferred to the Quick Reference Card as a
handy reference.
Filling out the Watering Schedule Form
When lling out the form provided on page 10, use a pencil
so changes can be easily made.
Refer to the example shown on the opposite page and
ll out your form in a similar manner. Include the following
information:
• Location  Identify the location of each watering
station area and the type of plant being watered.
Note: Enter the following information for each
program. If the program is not needed, leave its
information column blank.
• Watering Day Schedule  For a Calendar schedule,
indicate which day(s) of the week watering is desired.
For a Day Interval schedule indicate the desired
Interval number (1–31). For Odd or Even day watering
schedule, simply mark the appropriate box.
• Station Run Time Duration  Indicate the amount of
run time (1 minute to 4 hours) for each station. Write
“O” for any station which you do not want to run in
the program.
• Program Start Times  Indicate the time(s) of day to
start the program. Each program can have up to three
start times per watering day.
Important: The KD2 can run only one program
watering cycle at a time. Therefore, when setting more
than one start time for a program or when setting up
more than one program, make sure that each program
watering cycle will be able to run completely before the
next start time occurs. This can be easily determined by
totaling up the run time duration of all stations that will
operate during the program, then selecting the next start
time that can accommodate the completion of the initial
watering program. If Water Budget is used to increase run
time duration, this must also be considered in the total
run time. It is important to remember that a program start
time which occurs while a watering cycle is in progress
will be delayed (stacked) until the current watering
cycle is nished. If this happens, it may appear that the
sprinklers are not shutting o or that they are running at an
unexpected time of day.

About the KD2 Memory
The KD2 is equipped with nonvolatile memory and will
retain program information in the event that AC power
is lost or no battery is connected. The date and time are
maintained for up to 24hours in the event that AC power
is lost, but the user has the option of installing a 9volt
battery to maintain the date and time in the absence of AC
power in excess of 24hours.
Setting a Calendar Day Schedule
The Calendar Day schedule enables you to set each day of
the week as an active or inactive watering day. Each day
can be active or inactive in each program (A, B and C).

Setting a Day Interval Schedule
A Day Interval schedule enables watering days to be
set without regard to the actual days of the week. For
example, a 1day interval will water every day, a 2day
interval will water every other day and so on up to a
31day interval, which will water only once a month. The
active watering day is the last day of the Interval.
In order to establish a reference point for the beginning of
the Day Interval, the current day within the interval is also
entered. For example, if a 3day interval is selected and
“Today” is entered as day 2 of the interval, then watering
will occur tomorrow (the last day of the interval).
1. Turn the control dial to the Interval position.
2. Press the button as needed to select the desired
program. Program letter A, B or C will be displayed.
Note: If Odd or Even is displayed, an Odd/Even

Setting Program Start Time
The program start time is the time of day you select to
begin an automatic watering program cycle. When a
program starts, each station with a designated run time
duration in the program will operate in numerical order,
one station at a time. Sometimes it is necessary to run a
watering program more than once per day. For example,
when watering a new lawn. The KD2 provides three
independent start times per day for each program. Refer to

Controller Operation
The KD2 controller has ve modes of operation:
Automatic, Manual Station(s), Manual Programs, Test and
O. In the Automatic mode, the controller tracks the time
and day and operates the automatic watering schedules
as programmed. The Manual Station(s) mode enables an
individual station or group of stations to be started and
controlled manually. Manual Programs mode enables
watering programs to be started manually. Test mode
enables a quick, temporary program to be run to test the
operation of each station control valve. The O mode
prevents all station operation.
Automatic Operation
Automatic operation will occur whenever the programmed
start time and watering day matches the KD2’s internal
clock and calendar.
The HOME control dial position is the normal position
for the dial when automatic operation is desired. However,
the controller will operate automatically when the control
dial is in any position.
While an automatic watering program is running and the
control dial is in the HOME position, pressing the
button will manually advance from the activate station to
the next displayed station number in sequence
Manual Operation
Manual controller operations will override all currently
active automatic operation and sensor input. Any
automatic program start time that occurs during a manual
operation will be delayed until the manual operation is
terminated or concluded. Any automatic program delayed
past midnight will be postponed.
True Manual Operation
True manual operation allows a single station to be
selected and run without regard to run time duration.
Once started, the station will run until it is turned o or the
controller clock time passes midnight.
1. Turn the control dial to Manual Station position.
2. Press the button until the desired station number is
ashing and the display shows    (dashes).
3. Press the button once to activate the station. The
station number and ON will be displayed along with
the ashing watering symbol . Leave the dial in the
Manual Station position. The station will remain on
until operation is terminated or until midnight.
• To terminate operation prior to midnight, turn the
control dial to any other position or press any button.
4. Return the control dial to HOME position when
nished.

15
