Power ON Check
To perform a Power ON check:
1. Verify that the 24 Vac 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 controller.
4. Observe the UC400-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.

Interface (WCI)

®
A factory-installed Air-Fi Wireless Communications
Interface (WCI) provides wireless communication between

the Tracer SC and Tracer
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:

Wireless Zone Sensor (WZS) Set

A wireless zone sensor (WZS) set (sensor and receiver)
communicates wirelessly to a Tracer
wireless zone sensor set is an alternative to a wired sensor
when access and routing of communication cable are
issues. The sensor allows flexible mounting and relocation.

The Wireless Comm Interface (WCI) enables wireless
communication between system controls, unit controls, and
wireless sensors for the new generation of Trane control
products.The WCI replaces the need for communication
wire in all system applications.

Design Best Practices Guide
Quantity of WCIs per Network
Each Trane wireless network can have a total of 31 WCIs
(30 member WCIs plus one coordinator WCI). Each
network requires one WCI to function as network
coordinator.
Quantity of Networks per Tracer
®
A Tracer SC can support up to eight wireless networks.

Automatic Network Formation

When a WCI is connected to a Tracer
assigned as the coordinator.To enable the coordinator,
®
Tracer SC must be configured for wireless
®
communication.The coordinator WCI opens the network to
allow all WCIs having matching addresses to automatically
join the network. If no Tracer
located WCI must be designated to act as the coordinator.
