Replacing a Wireless Valve Output Module
The Recover Database feature is used when a WVOM-E
must be replaced for service reasons or is exchanged with
another device.
• The new WVOM-E must be relinked to all the WVLs in the
eld to operate.
• Connect with the app to the new WVOM-E.
• Install the new WVOM-E, connect with the app, and
choose the Recover Database feature.
• The app will prompt you to enter the serial number of
a known device (either a WVL or a Repeater) within the
system.
• The WVOM-E will use this known-good valid serial
number to search for that device. The WVOM-E will then
attempt to reach all operational WVLs or a Repeater
within range. This can take up to 30 minutes.
• When the process is complete, a notication will appear.
If all WVLs were found, the WVOM-E will be ready to
irrigate again without further eld addressing.
Problem Causes Solution
WVL not watering Dead batteries. WVL not addressed.
Improper solenoid or solenoid disconnected.
WVL out of communication range.
Use manual test function, replace batteries.
Verify WVL address (start from controller).
Use manual test function, check solenoid wiring including polarity (red and black).
Improve radio communications.
Multiple stations turn on Possible duplicate addresses in WVLs Stop all irrigation, then start one of the stations.
If multiple stations start, change the address in one of the WVLs.
Controller beeping No response from WVL.
Low battery warning from WVL.
Use the Hunter WVL App to read which condition is being reported.
Install new batteries and/or improve communications, as indicated.
Controller Err display (usually
together with beeping)
No response from WVL.
Low battery warning from WVL.
Possible failure on another output module.
Use the Hunter WVL App to read which condition is being reported. Replace batteries,
improve communications, as indicated. Troubleshoot other output modules.
Station turns on for 1 second,
then shuts o
WVL is wired to AC Solenoid
(not compatible)
Replace the solenoid with the required DC-Latching Solenoid (P/N 458200). Red
wires to red, black to black.
Troubleshooting
In most cases, troubleshooting is best done with the Hunter WVL App open on a smartphone.
