Note:
If no network sensor is connected, the startup
of the default state is delayed by 30 seconds while
the controller attempts to establish a connection
with the sensor.
After you validate the wiring, use CCT to download an
actual standard or custom application.
Troubleshooting
The following table contains troubleshooting information for the VAV controller. Table 13 provides LED status indicator
information for troubleshooting the controllers.
Note:
If you experience short circuits in the 24 VAC power supply causing protective devices such as breakers or
fuses to trip, make sure that the power connections on the VAV controller are not reversed. The most common
cause of this problem is when the 24 VAC power supply on the controller is reversed but not reversed on a
connected secondary device. Improper wiring of this power terminal may cause a short circuit across the 24 VAC
power supply.
