Air-Fi® Wireless Communications System - Trane VUV Installation, Operation And Maintenance Manual

Installation - Controls
Note: A pigtail connection may be necessary between earth
ground and/or enclosure ground if the device is not
grounded through one leg of the transformer wiring.
.
Power ON Check
To perform a Power ON check:
1. Verify that the 24Vac connector and the chassis ground are
properly wired.
2. Remove the lockout/tagout from the line voltage power to
the electrical cabinet.
3. Energize the transformer to apply power to the UC400-B/
Symbio™ 400-B controller.
4. Observe the UC400-B/Symbio™ 400-B controller when
power is applied to verify the power check sequence as
follows:
a. The power LED lights red for 1 second
b. The power LED lights green
• If the sequence above is completed as described, the
controller is properly booted and ready for the
application code.
If the power LED flashes red, a fault condition exists.
The controller is mounted, pre-wired, and pre-programmed to
selected control components best suited for room comfort. For
more information on the UC400-B/Symbio™ 400-B unit

Air-Fi® Wireless Communications
Interface (WCI)
A factory-installed Air-Fi® Wireless Communications Interface
(WCI) provides wireless communication between the Tracer®
SC and Tracer® unit controllers. The Air-Fi® WCI is the perfect
alternative to a Trane BACnet® wired communication link.
Eliminating the communication wire between terminal
products, space sensors, and system controllers has
substantial benefits:
• Reduced installation time and associated risks.
• Completion of projects with fewer disruptions.
• Easier and more cost-effective re-configurations,
expansions, and upgrades.
Air-Fi® Wireless Communications Sensor
(WCS)
Communicates wirelessly to a Tracer® unit controller. A WCS
is an alternative to a wired sensor when access and routing of
communication cable are issues. A WCS allows flexible
mounting and relocation.
