3 Common EC-Net & JACE Issues (and How to Fix Them Fast)

This guide walks through three common EC-Net and JACE issues that frequently surface during startup and commissioning. You’ll learn how to quickly recognize the symptoms, understand what’s actually causing the problem, and apply proven fixes that get systems back online without unnecessary rework. The focus is on practical, field-tested troubleshooting — helping you avoid delays, licensing headaches, and wasted time on site.


EC-Net & JACE Tech Guide

3 common issues that can stall commissioning — plus quick fixes to get you moving again.

Troubleshooting Quick Fixes Licensing Checks

1) Wizard won’t launch on GEN2 ECY

Often after installing the EC-Net support pack on non-Distech JACEs.

Symptom

Connection attempts fail, or you see: “connected host failed to respond.”

Solution

Install the Distech EC-Net Facilities “Unified Package” from the Distech Controls Software Center under the EC-Net Platform tab.

2) “Not Licensed” on a Distech JACE

Wizard appears unlicensed even on genuine Distech hardware.

Cause

Likely a version mismatch between the JACE software revision and the installed support pack.

Solution

Update the EC-Net support pack to the latest version via the Software Center. If issues persist, perform a full reinstall.

3) JACE 9000 Host ID mismatch

Workbench Host ID doesn’t match the SD card Host ID.

Symptom

Host ID in Workbench is missing the “SD” prefix.

Solution

Power down the JACE, reinsert the SD card, then power back up to pull the correct Host ID.

Pro Tip

Always verify the Host ID in Platform > License Manager before requesting or moving licenses — make sure it includes the “SD” prefixed ID.
