Underhill ICC Decoder Module Troubleshooting Guide

Observed Field Condition
8) “The Hunter ICC continuously displays an “ERR” message when irrigating any
station manually or from a scheduled start. All of the stations are operating without
any issues. Why does this occur?”
Possible Causes
This message is typically displayed when the Hunter ICC controller is connected to a
Roam or Roam XL hand-‐held receiver or Solar Sync.
How to Troubleshoot
Verify if a blue-‐colored capacitor has been installed on the Hunter ICC’s power module.
Generally if this capacitor is missing, the “ERR” message will appear. Call Underhill
International and request the quantity of capacitors needed. There is a no-‐cost fee for
these that come complete with installation instructions.
If a capacitor exists and the “ERR” message is still observed, verify the capacitor is
making contact with the terminal blocks and/or is installed properly. See diagram
