Trane Air-Fi WCS-SB Installation, Operation And Maintenance Manual page 65

For these applications with BACnet MS/TP or BACnet/IP network communication and wireless sensors,
a WCI coordinator at the Tracer SC+ is NOT required. Instead, one unit controller WCI is designated as
a coordinator – exactly one coordinator for each network. Refer to the instructions below for proper
installation.
To begin, configure the unit controllers, WCIs, and sensors as if the network configuration was Air-Fi
Wireless. Once the Air-Fi Wireless operation is confirmed, change the network communication protocol
from Air-Fi Wireless (BACnet over Zigbee) to BACnet MS/TP or BACnet/IP. By first establishing the Air-
Fi Wireless connections, the controller automatically sets up the sensor reference(s) for the WCI.
Important: Concurrent Air-Fi Wireless (BACnet over Zigbee) and BACnet MS/TP or BACnet/IP

hour, indicating that the network is open to allow WCIs with matching addresses to join the network
for that duration. After each WCI joins, the 1-hour timer starts over.
Note: If the network closes because the timer has expired, you can open the network for an
additional hour by pressing the OPEN_NET button on the network coordinator WCI. To
extend time on a network that has not yet closed, press the OPEN_NET button on the
coordinator to close the network, then press it again to open the network for an additional
hour.
Note: Typically, it takes about 10 minutes for a WCI to join the network. However, the time is
dependent on the distance between the WCIs in network as well as the size and type of
structures that may exist between them.
