General Information
This section provides general information about the wireless Comm interface (WCI).
Product Description
TheTrane® Wireless Comm Interface (WCI) enables wireless communication between system
controls, unit controls, and wireless sensors for the new generation ofTrane control products.The
WCI replaces the need for communication wire in all system applications.
Types of Devices Supported by the WCI
• Tracer™ SC system controller
• Tracer™ UC210 programmable controller
• Tracer™ UC400 programmable controller
• Tracer™ UC600 programmable controller
• BCI-I: BACnet Communications Interface for IntelliPak™ systems
• BCI-R: BACnet Communications Interface for ReliaTel™ systems
• Tracer™TU
• Wireless zone sensors
Quantity of WCIs per Network
EachTrane wireless network can have a total of 31WCIs (30 member WCIs plus 1 coordinator WCI).
Each network requires one WCI to function as network coordinator.
Quantity of Networks per Tracer SC
ATracer SC can support up to 8 wireless networks.
Notes:
• The number of WCIs that can be installed at a site is determined by the applicable
Tracer SC license, which specifies the total number of controllers.
• For information about installing aWCI on aTracer SC, see “Mounting andWiring theWCI,”
p. 13 and Figure 6, p. 15.
Automatic Network Formation
When a WCI is connected to aTracer SC, it is auto-assigned as the coordinator. To enable the
coordinator,Tracer SC must be configured for wireless communication.The coordinator WCI
opens the network to allow allWCIs having matching addresses to automatically join the network.
If noTracer SC is present, a centrally located WCI connected to a programmable controller or a BCI
must be designated to act as the coordinator.You can manually set the coordinator WCI so allWCIs
having matching addresses automatically join the network.
Note: For additional information, see “Establishing the Network,” p. 18.
Wireless Zone Sensors
TheWCI also communicates withTrane wireless zone sensors, eliminating the need for standalone
receivers.
Wired Zone Sensors
Systems using Wireless Comm can also use wired zone sensors.
Network Security
The WCI uses standard ZigBee™ Building Automation security practices by the use of AES128
encryption, keys, and device authentication.
