Firmware Requirements for Devices in an Air-Fi Wireless Network

Minimum Firmware Levels Table

Lists minimum firmware levels required for devices to participate in an Air-Fi® Wireless network.

The Trane Air-Fi® Wireless Communications Interface (WCI) is a crucial component in Trane's Air-Fi® wireless network, designed to facilitate communication between various HVAC system controllers and the network. It acts as a bridge, enabling wireless connectivity for devices that might otherwise require wired connections, thereby simplifying installation and offering greater flexibility in system layout.

Function Description:

The WCI serves multiple roles within the Air-Fi® wireless network:

Network Coordinator: In a Trane Air-Fi® wireless network, one WCI is designated as the Network Coordinator. This WCI is responsible for establishing and maintaining the wireless network, managing communication between all other WCIs and unit controllers, and ensuring the overall stability and integrity of the network. It acts as the central hub for wireless data exchange.
Standard WCI: Other WCIs in the network function as standard communication interfaces, allowing various Trane unit controllers (such as UC210, UC400, UC600, BCI-I, BCI-R, RTRM) to join the Air-Fi® network wirelessly. They receive data from the unit controllers and transmit it to the Network Coordinator, and vice-versa.
Repeater (Optional): A WCI can also be configured as a Repeater, extending the range and improving the reliability of the wireless network. This is particularly useful in large installations or environments with obstacles that might impede direct communication between devices. When configured as a Repeater, the WCI relays signals between other WCIs and the Network Coordinator, ensuring that all devices can communicate effectively.
Integration with Tracer SC/SC+: The WCI integrates seamlessly with Trane Tracer SC and Tracer SC+ controllers. These controllers can manage one or more wireless networks, with the WCI acting as the interface for these networks. The Tracer SC/SC+ provides the necessary power and communication backbone for the WCI.

Important Technical Specifications:

Model Numbers: The WCI is available under several model numbers, including X13790901030, X13790902030, X13790903030, X13790904030, and X13790941030.
Power Requirements: The WCI typically operates on 24VAC/DC. This power is supplied by the connected controller (e.g., Tracer SC/SC+, UC210/400/600, BCI-I, BCI-R).
- For Tracer SC/SC+ installations, the WCI connects to the IMC terminals on the PM014 module, which provides the 24Vdc.
- For BCI-I (IntelliPak/CSC), the WCI connects to the +24Vdc and GND terminals.
- For BCI-R (ReliaTel™: Voyager™, Precedent™™, and Odyssey™™), the WCI connects to the 24VAC/DC and GND terminals.
- For UC210/400/600, the WCI connects to the +24Vdc and GND terminals.
Communication Interface: The WCI uses a 2-connector screw terminal block for its LINK+ and LINK- connections, which are used for communication with the unit controller. It also has terminals for power (+24Vdc/VAC and GND).
Minimum Firmware Levels: To ensure proper operation and compatibility within the Air-Fi® wireless network, specific minimum firmware levels are required for both the WCI and the connected unit controllers.
- WCI: V2.00.xxx
- Tracer SC: All versions
- Tracer SC+: V2.00.xxx
- UC210: V5.00.xxx
- UC400: V5.00.xxx
- UC600: V5.00.xxx
- BCI-I: V5.00.xxx
- BCI-R: V5.02.xxx (or higher if requires physical module)
- RTRM: V1.2 (or higher if requires physical module)
- Tracer TU: V8.2
- TU Adapter: V1.00.xxx
LED Indicators: The WCI features several LEDs that provide visual feedback on its operational status:
- Network LED (green): Flashes for 10 seconds during network activity, then turns solid ON when a network is joined. A solid ON indicates the WCI is a member of a network.
- Coordinator LED (yellow): Solid ON when the WCI is the network coordinator.
- Open NET LED (yellow): Solid ON when the network is open for joining.
- Reception LED (yellow): Flashes when data is received.
- Transmission LED (green): Flashes when data is transmitted.
- TX Link LED (yellow): Flashes when data is transmitted via the link.
- Diagnostic LED (red): Flashes (3 seconds on, 3 seconds off) for a network failure or solid ON for a radio failure. A double flash pattern indicates a communication issue with the controller.
- Power LED (green): Solid ON when the WCI has power.

Usage Features:

Address Setting: The WCI requires address setting, which is a crucial step during installation. This process involves configuring the WCI to join an existing network or to become the Network Coordinator. The installation instructions provide detailed steps for this, often referring to external documents like the "Air-Fi® Wireless Installation, Operation, and Maintenance" and "Air-Fi® Wireless Network Design Best Practices Guide."
Wiring Harness Connection: The WCI connects to various Trane controllers via a wiring harness. The wiring diagrams provided in the manual illustrate how to connect the WCI to UC210/400/600, BCI-I, BCI-R, and Tracer SC/SC+. Color coding for the wiring harness is standardized: Red for +24VDC/VAC, Black for GND, Blue for LINK+, and Gray for LINK-.
Link Select Switch: For BCI-R connections, a link select switch is present on the WCI to configure the communication link.
PM014 Module Integration: When integrating with Tracer SC/SC+ for multiple wireless networks or to manage power budgets, a PM014 module is used. The WCI connects to the IMC terminals on the PM014.
Power-On Sequence: When powering on multiple devices in an Air-Fi® network, a specific sequence is recommended to ensure proper network initialization:
1. All WCIs
2. All unit controllers (UC210, UC400, UC600, BCI-I, BCI-R)
3. All Tracer SCs
4. All WCSS (Wireless System Sensors)

Maintenance Features:

Diagnostic LEDs: The various LED indicators on the WCI are essential for troubleshooting and maintenance. They provide immediate visual feedback on the device's status, network connectivity, and potential communication issues. For example, a flashing red Diagnostic LED can indicate a network failure or a radio issue, while a double flash points to a communication problem with the connected controller.
Firmware Updates: Maintaining the minimum required firmware levels for both the WCI and connected controllers is crucial for optimal performance and compatibility. Regular checks and updates as per Trane's recommendations ensure the system operates efficiently and securely.
Safety Precautions: The installation instructions emphasize safety, stating that only qualified personnel should install and service the equipment. Disconnecting all electric power, including remote disconnects, and following proper lockout/tagout procedures are mandatory before servicing to prevent serious injury or death.

In summary, the Trane Air-Fi® Wireless Communications Interface is a versatile and integral component of Trane's wireless HVAC control systems, offering flexible installation, robust communication, and clear diagnostic capabilities through its LED indicators. Its ability to act as a coordinator, standard interface, or repeater makes it adaptable to various system sizes and complexities, while its integration with Tracer SC/SC+ controllers provides a comprehensive solution for building management.
