Introduction
The Hunter Wireless Valve Controller (WVC) is a battery-
powered, radio programmable controller that can operate
one (WVC-100), two (WVC-200), or four (WVC-400)
valves. Hunter’s wireless, battery-powered irrigation
systems are ideal for commercial/municipal applications
such as street and highway landscaping, medians, parks,
construction sites, and other areas that do not have
access to power.
All programming and manual operations for the WVC
are accomplished with the Wireless Valve Programmer
(WVP). The WVP is a handheld programmer that allows
you to create programs and conduct manual operations
with WVC controllers in the eld. Because the WVP
retrieves and transmits data via radio signals, you never
have to open a valve box to check the status or program
your controllers.

WVC Components
This section provides an overview of the components of
the WVC. Each item will be discussed in further detail
later. However, this section can be helpful in getting
acquainted with the available options.
1. WVC Body – The WVC controller is designed to be dirt
tolerant, waterproof, and submersible to 12'(3.7 m).
2. External Antenna – Flexible rubber antenna for radio
communication.
3. 9-Volt Battery Holder – The WVC is designed to
operate on a single 9-volt alkaline battery. The battery
easily snaps into the battery holder.
4. Wires for DC Latching Solenoids – Leads are provided
for wiring DC latching solenoids. The red wires are
numbered on top of the WVC to provide station
identication. The black wire is the common wire.
5. Weather Sensor Wires – A Hunter Mini-Clik®or other
micro-switch-type sensor can be connected to the
WVC.
6. Valve Mounting Clip – Allows the WVC to be mounted
directly to any Hunter valve. The clip can also be used in
conjunction with the Universal Mounting Adapter.
7. Universal Mounting Adapter – Allows for alternate
methods of mounting the WVC. It can be used to
mount the WVC to the side of the valve box or on a ½"
(13 mm) diameter section of plastic pipe.
8. LED Indicator Light – Used when setting the WVC
address.

Installing the Battery
Note:
The WVC has non-volatile memory that retains
all program information when the battery is
removed or in the event the battery is drained.
The WVC uses a standard 9-volt alkaline battery to
operate the valve and program the controller. Battery life
is aected by the number of valve actuations, along with
the distance the solenoids are from the controller. Under
normal service conditions the battery should provide at
least one full year of service. 3. Make sure no water is inside the battery compartment.
Make sure that the seals are in good condition.
Screw the WVC body halves together to seal the
compartment.
Note:
The battery holder is designed so that the
battery can only be inserted in one direction.
To Install the Battery
1. Unscrew the rear half of the WVC body to gain access
to the battery compartment.
2. Snap the battery into the battery holder.

6
Wiring DC Latching Solenoids to the WVC
Leads are provided to attach a Hunter DC latching
solenoid or other two-wire, low-voltage latching solenoids
to the WVC (Hunter DC latching solenoid part #458200).
Hunter DC latching solenoids have two leads: one colored
black and the other red.
To Connect DC Latching Solenoids
1. Select the appropriate station wire (red wire) on the
WVC. Note: Station numbers are identied on top of
the WVC. Strip away ½" (13 mm) of insulation from the
station wire.
2. Remove ½" (13 mm) of insulation from the common
wire (black wire) on the WVC.
3. Twist the red and black leads from the solenoid to the
red and black leads on the WVC as shown in the gure.
4. Make sure to use waterproof connectors to secure all
wire connections.
Note:
The maximum recommended distance from
the WVC to any Hunter DC latching solenoid
is approximately 100'(30 m) with 18-gauge
wire. Long distances between the WVC and the
DC latching solenoid will reduce overall 9-volt
battery life.

Note:
The black wire from each solenoid must be wired
to the single black lead on the WVC controller.

Radio Communication
All programming and manual operations with the WVC
can be controlled with the WVP. Actual performance
varies depending upon the installation and the
surrounding terrain. The WVP can send/retrieve data to/
from the WVC up to 100'(30 m) with the WVC installed in
the valve box below ground level. Radio range increases
when the WVC is installed above ground. (Refer to the
WVP Owner’s Manual regarding radio communication).

Addressing the WVC With the WVP
WVP required to perform this function
Each WVC controller requires a unique
identication number for proper radio operation
with the WVP. Setting unique addresses for each
WVC allows for separate radio programming and
manual operations with individual WVC controllers
even though other controllers may be in the
surrounding area. The unique address is a 3-digit
number from 000 to 999. Once the address is set,
you must remember the ID for future operation.
(Refer to the WVP Owner’s Manual for detailed
programming instructions).
To Set the Unique Address on the WVC
1. Press the Transmit/Receive button on the WVP
to enter the communications mode (lower portion
of display).
2. Use the and buttons to change the 3-digit
identication number. Use the button to make
sure that the WVP is in the transmit mode with the
arrow on the display pointing towards the address icon
(see Figure 1).
3. Unscrew the rear half of the WVC body to gain access
to the battery compartment.
4. Install a standard 9-volt alkaline battery
into the battery holder (see Connecting the
Battery).
5. Wait for the red light inside the battery
compartment to come on; this may take 10-15
seconds.
6. Immediately press and hold the Transmit/
Receive button on the WVP. The WVP will
beep twice when transmission commences.
Release the button.
7. The WVP will beep twice again when it learns
the identication number.
8. If the WVP illuminates the failed to
communicate icon , start over from
step 4.
Figure 1
Note:
If no WVP communication takes place aer the
red light on the WVC comes on, the WVC will
turn this light o (aer 20 seconds) and revert
back to the address already programmed into
the WVC.

Mounting the WVC to a Hunter Valve
The WVC can easily be mounted on any Hunter plastic
valve. A specially designed valve mounting clip makes
installation a snap.
Note:
When mounting the WVC, position the antenna
vertical and as high as possible in the valve
box to achieve maximum range for radio
communication.
Figure 2
To Mount the WVC to a Valve (Figure 2)
1. Unscrew the existing solenoid from the valve.
2. Screw the WVC latching solenoid into the valve bonnet.
3. Attach the large end of the valve mounting clip to the
middle of the WVC body (mounting clip supplied with
your WVC).
4. Snap the small end of the valve mounting clip to
the solenoid.
Note:
The total length of wire from the WVC to the
solenoid should not exceed 100' (30 m).

Alternate Mounting Methods
A universal mounting clip and mounting adapter are also
provided with the WVC. These accessories provide 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 3)
1. Position the universal mounting adapter on the side of
the valve box. Make sure that the bracket is positioned
so that the controller is as high up in the valve box as
possible, but does not interfere with the top of the
valve box cover.
2. Drive two screws to secure the adapter to the side of
the valve box.
3. Attach the WVC to the mounting clip and slide it on the
end of the mounting adapter.
Stake Mounting Method (Figure 4)
The universal mounting adapter can also be used to stake
mount the WVC.
1. Cut a section of ½" (13 mm) diameter plastic pipe.
2. Drive the pipe into the ground inside the valve box to
position the WVC to the desired height.
3. Slip the universal mounting adapter on top of the pipe.
4. Attach the WVC to the mounting clip and slide onto the
adapter.

Connecting a Weather Sensor
Connecting a Weather Sensor
A Hunter Mini-Clik®rain sensor or other micro-switch-
type weather sensor can be connected to the WVC. The
purpose of this sensor is to stop watering when weather
conditions dictate.
To Connect a Weather Sensor to the WVC
1. Cut the yellow wire loop attached to the WVC at
approximately the middle of the loop.
2. Remove approximately ½" (13 mm) of insulation from
each wire. Attach each wire to each of the wires of the
weather sensor.
3. Secure both wire connections with waterproof
connectors.
Programming the Controller
The WVC is simple to program with its companion,
the WVP Wireless Valve Programmer. The easy-to-
understand push-button design of the WVP allows you to
