WIRELESS VALVE OUTPUT MODULE

INSTALLATION GUIDE

WVOM Wireless Valve Output Module for Hunter ICC2 and HCC Controllers

Components

You will need:

WVOM Bluetooth® App (free download from Apple or Google Play)
Two 9 V DC batteries for each Wireless Valve Link to be connected
Irrigation-grade, waterproof connectors for DC solenoid connections
1½" (38 mm) hole saw for Wireless Valve Link valve box lid mounting (included)

Note: Do not use the hole saw on the controller enclosure! The hole saw is for installing the individual Wireless Valve Link devices in valve boxes.

The Wireless Valve Output Module (domestic WVOM or international WVOM-E model) is designed for installation in an output module slot within a compatible Hunter ICC2 or HCC Controller.

The Wireless Valve Output Module is designed to operate with Hunter Wireless Valve Link devices only. It is not compatible with any other manufacturer's devices.

The Wireless Valve Link requires Hunter DC-Latching Solenoids (P/N 458200), which can be retrofitted to almost any existing Hunter valve.

Installation

Follow these steps to install the Wireless Valve Output Module:

Engage the tabs in the output module slot and tip the Wireless Valve Output Module into place until the connector is fully seated.
Move the locking lever to the horizontal position to secure the module.
Press and release the Reset button on the back of the facepack so the new module is recognized. The controller can now manage 54 stations.
When powered on, the module's top LED will display a constant green light to indicate it is active and ready to communicate.

? Note: PMV Connection: If wireless control of a PMV output will be used, connect a jumper wire from the PMV terminal on the Wireless Valve Output Module to the PMV output on the controller power module.

Diagram Description: The installation diagram shows the module being inserted into a controller slot, secured by a lever. A separate inset shows the reset button. Another inset illustrates the P/MV jumper wire connection.

Station Programming

The WVOM has no built-in controls; all programming and diagnostics are done with the free Bluetooth WVL App, available for iOS® or Android® from their respective app stores.

Download and install the Hunter WVL App.
Open the app on a smartphone. The app will begin scanning for Wireless Valve Output Modules within a range of roughly 50' (15 m) line of sight.
A list of available Wireless Valve Output Module devices within Bluetooth range will appear, identified by serial number.
Select the Wireless Valve Output Module you're programming and click Connect. The blue LED on the selected Wireless Valve Output Module will light up when it's connected to the phone.
Consult the Wireless Valve Link installation guide for programming station addresses into the Wireless Valve Links.

? Note: The Hunter WVL APP is designed for WVL programming and diagnostics. There is no station manual operation feature within the app.

Basic Troubleshooting

All LoRa® radio communications between the Wireless Valve Output Module and the Wireless Valve Links (or Repeater) are two-way. The module expects a response after sending a message.

If the module does not receive a response after a retry attempt, it will announce an error in the controller display and with two internal beeps every 2 minutes. The display will show the station number (or P for Pump/Master Valve) along with "Err". The beep continues until the module communicates successfully or the controller's Reset button is pressed.

Use the WVL App to connect to the module and go to the Dashboard menu. Click Details. Any Wireless Valve Link with a red status icon has failed to respond.

Common Communication Failures:

Cause	Solution
Low battery	Replace batteries (or inspect solar panel, if using solar power)
Environmental changes (e.g., obstructing vehicle, overgrown foliage)	Locate and remove obstacle, if possible. Elevate Wireless Valve Output Module antenna. Add Repeater.
Radio interference from other devices	Try a different channel (use the app) to eliminate interference.
WVL internal failure (e.g., lightning)	Check Wireless Valve Link LEDs in battery compartment for functionality. Replace Wireless Valve Link if necessary.

Range Extension:

Elevate the Wireless Valve Output Module antenna with a Hunter Antenna Extension Kit up to 9' (3 m). This kit is required for use in metal cabinet controllers.
Add a Hunter Repeater (model RPT in North America, RPT-E in international markets).

Additional Functions

Passcode Creation

You can add a passcode (PIN) to prevent unauthorized access by other Bluetooth smartphone users. Remember your passcode or store it safely. If forgotten, other users may not be able to access the module and its information until it's bypassed. Do not use a PIN from other apps.

Database Recovery

This feature is used when a Wireless Valve Output Module needs replacement. The new module must be relinked to all Wireless Valve Links in the field. Install the new module, connect with the app, and choose "Recover Database". The app will prompt for a known device's serial number. The module will search for and attempt to reach all operational devices within range (can take up to 30 minutes). A notification will appear upon completion.

Factory Reset

This option erases all module information, including the Wireless Valve Link database, Channel and Site ID assignments, and Repeater configuration. The system will need to be set up again. From the WVOM Settings menu, select "Factory Reset".

Firmware Updates

Both the Wireless Valve Output Module and Wireless Valve Links can be updated over the air (OTA) if new firmware is available. A notification will appear upon completion.

? Note: Firmware updates are large downloads and can take up to 2 hours. Do not start an update if irrigation or other diagnostics are needed within this time.

Compliance

FCC

This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules. These limits provide reasonable protection against harmful interference in residential installations. The equipment generates, uses, and can radiate radio frequency energy. If not installed and used per instructions, it may cause harmful interference to radio communications. No guarantee is made that interference will not occur in a particular installation. If interference occurs, try correcting it by:

Reorienting or relocating the receiving antenna.
Increasing separation between the equipment and receiver.
Connecting to an outlet on a different circuit than the receiver.
Consulting the dealer or an experienced radio/TV technician.

Changes or modifications not expressly approved by Hunter Industries could void the user's authority to operate this device. Consult a Hunter Industries representative or technician for suggestions.
