All LoRa® radio communications between the Wireless Valve Output Module and the Wireless Valve Links (or Repeater) are two-way. Whenever the Wireless Valve Output Module sends a message to the Wireless Valve Links or the Repeater, it expects a response.
The two-way communications occur every time the controller attempts to turn on a Wireless Valve Link station.
If the Wireless Valve Output Module does not receive a response after a retry attempt, the module will announce the error both 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 to indicate which station failed to respond.
- The beep will continue until either:
- the Wireless Valve Output Module is able to communicate successfully with the unresponsive Wireless Valve Link again, or
- you press the Reset button on the back of the controller facepack.
Use the WVL App to connect to the Wireless Valve Output Module, and go to the Dashboard menu. Click Details. Any Wireless Valve Link with a red status icon has failed to respond.
The most common causes of communication failures are:
| Cause | Solution |
|---|---|
| Low battery | Replace batteries (or inspect solar panel, if using solar power) |
| Environmental changes (e.g., obstructing vehicle, overgrown foliage) |
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 |
- Elevate the Wireless Valve Output Module antenna with a Hunter Antenna Extension Kit up to 9' (3 m). The Antenna Extension kit is required for use in metal cabinet controllers.
- Add a Hunter Repeater (model RPT in North America, RPT-E in international markets).
