Controller LEDs
This section describes how to verify and interpret the UC210 controller LEDs and safely operate the
controller. LEDs are used to provide controller serviceability. The UC210 controller has the
following LEDs located on the front (refer to Figure 9 and Table 8, p. 26):
• Marquee LED
• Communication status LEDs and IMC status LEDs
• Service button LED
• Five (5) TRIAC status LEDs
For details about wiring communication links, refer to the BACnet Best Practices and
Troubleshooting Guide (BAS-SVX51-EN).
