CONNECTING THE BATTERY To Install the Battery
1. Unscrew the rear half of the SVC body to gain access to
the battery compartment.
2. Snap the battery into the battery holder (use a high
quality 9 volt akaline battery).
NOTE: The battery holder is designed so that
the battery can only be inserted one way.
3. Make sure no water is inside the battery compartment.
Screw the SVC body halves together to seal the
compartment.
The SVC uses a standard 9-volt alkaline battery (not
included) to operate the valve and program the controller.
Under normal conditions the battery should provide at least
one full year of service. Use of a 9-volt lithium battery will
extend the service life of the SVC between battery changes
(approximately 3 years).
NOTE: The SVC has non-volatile memory
which allows for the battery to be removed
without losing any program information.

ATTACHING SOLENOIDS
The SVC-100 is provided with a solenoid attached to
the controller. The SVC-200 and SVC-400 multi-station
controllers will operate up to 2 or 4 solenoids, respectively.
Hunter DC solenoids (P/N 458200) can easily be installed
on all Hunter Plastic Valves. For the SVC-200 & SVC-400,
solenoids must be ordered separately.
NOTE: Must use DC Latching Solenoids.
24VAC Solenoids will not operate with
the SVC.
To Wire DC Solenoids to the SVC
1. Attach the black leads from each solenoid to the single
common wire (black lead) coming from the SVC. Secure
all wire connections with waterproof connectors.
2. Attach one red wire from each solenoid to the cor-
responding station wire (red lead) from the SVC. The
station numbers are identified on the face of the SVC.
Secure all wire connections with waterproof connectors.
NOTE: The maximum wire distance between
the solenoid and SVC is 100 feet (18 gauge
minimum wire size).
The SVC can also operate non-Hunter DC latching sole-
noids. Below is a list of SVC compatible solenoids.

MOUNTING THE SVC
The SVC can easily be mounted on any Hunter plastic valve.
A specially designed valve mounting clip makes installation
a snap. A protective rubber cover is provided to prevent dirt
from accumulating on the face of the SVC.
To Mount the SVC to a Valve (Figure 1)
1. Unscrew the existing solenoid from the valve.
2. Screw the Hunter DC latching solenoid (P/N 458200)
into the valve bonnet.
3. Attach the large end of the valve mounting clip to the
middle of the SVC body.
4. Snap the small end of the valve mounting clip to
the solenoid.

Adapter
Along with the universal mounting clip, a mounting adapter
is also provided with the SVC. This mounting adapter
allows for alternate methods of mounting the controller
either to the side of the valve box or stake mounted within
the valve box.
Valve Box Mounting Method (Figure 2)
1. Position the universal mounting adapter on the side of
the valve box. Make sure that the bracket is positioned
so that the controller will not interfere with the valve
box cover when closed.
2. Drive two screws to secure the adapter to the side of
the valve box.
3. Attach the SVC to the mounting clip and slide it on the
end of the mounting adapter.

Stake Mounting Method (Figure 3)
The universal mounting adapter can also be used to stake
mount the SVC.
1. Cut a section of ½" diameter plastic pipe.
2. Drive the pipe into the ground inside the valve box to
the desired height of the controller.
3. Slip the mounting adapter on top of the pipe.
4. Attached the SVC to the mounting clip and slide onto
the adapter.
A Hunter Mini-Clik® rain sensor can be connected to the
SVC. The purpose of this sensor is to stop watering when
weather conditions dictate.
NOTE: When the Rain Sensor is interrupt-
ing the watering, the display will show the
System Off icon , “OFF” and on
the display.
1. Cut the yellow wire loop attached to the SVC at approxi-
mately the middle of the loop.
2. Remove approximately ½" (13mm) of insulation from
each wire. Attach one yellow wire to each of the wires
of the weather sensor. You can mount the rain sensor
up to 100 feet from the SVC controller (18 GA minimum
wire size).
3. Secure wire connec-
tions with waterproof
connectors.

The SVC utilizes independent station programming.
For each station being programmed, you need to program
at least one Start Time, a Run Time, and Water Day(s).
The button allows you to quickly navigate among
programming options.
The SVC display shows time and day when the button
is pressed. The button allows you to easily navigate
among programming options. During a short period of
inactivity, the display will shut off to retain battery power.
When programming, the flashing portion of the display can
be changed by pressing the or buttons. To change
something that is not flashing, press the or buttons
until the desired item is flashing.
The SVC allows for up to 9 start times per day. Multiple
start times permit morning, afternoon, and evening water-
ing, perfect for the establishment of new lawns and thirsty
annual flowers. Simply designate the days of the week you
want to water. The SVC makes it easy.
Setting the Date and Time
1. Press the button until the Current Time/Day icon
is displayed.
2. Hours will be flashing. Press the or button to
change the hour shown on the display. Press the to
proceed to setting the minutes.
3. Minutes will be flashing. Use the or button to
change the minutes shown on the display. Press the
to proceed to select AM, PM, or 24 hour time.
4. The time will be displayed, and the time of day flashing.
Press the or button to select AM, PM, or 24 hour.
Press the to proceed to setting the day of the week.
5. The number 1 will be flashing at the bottom of the
display, indicating the first day of the week. Press
the or buttons to select the day of the week
(1 through 7) corresponding to the day.
The time and day have now been set.
Setting Watering Start Times
1. Push the button until the Start Times icon is
displayed. A Start Time or “Off” will be flashing. The
number directly to the left of the start time number
(1 through 9) indicates the start time number. The
number directly below the start time number indicates
the station being programmed.
2. Use the or button to change the start time.
(The start times advance in 5 minute increments.)
