1. Safety

NOTE: Use 18-gauge color-coded thermostat cable for proper wiring. Shielded cable is not typically required.

Keep this wiring at least one foot away from large inductive loads such as Electronic Air Cleaners, motors, line starters, lighting ballasts and large distribution panels.

Failure to follow these wiring practices may introduce electrical interference (noise) which can cause erratic system operation.

All unused thermostat wires should be grounded at indoor unit chassis ground only. Shielded cable may be required if the above wiring guidelines cannot be met. Ground only one end of the shield to the system chassis.

2. Product Specifications

* On every application, 24VAC loads should be reviewed to be sure the indoor unit control power transformer is adequately sized.

4. Trane® Link Systems

• Installation: Trane Link systems are built to be "plug and play". Once you've connected the outdoor unit, indoor unit, SC360, and UX360, turn on the system. The equipment will communicate and configure the system automatically to default settings.
• Verification: You can easily verify all modes of operation. Link can run and verify each mode of operation as well as verify the system is functioning properly. For example, instruct the system to deliver 1200 CFM of airflow, and the system will verify correct operation. Once testing has been completed, you can get a commissioning report that documents the results.
• Monitoring: With a homeowner's permission, you can monitor data from the system remotely. This includes creating a birth certificate that captures how the system was operating on day one, and tracking performance over time.
• Upgrades: Connected systems can have their software remotely upgraded through the SC360, including pushing additional features out to the installed communicating equipment. No dealer visit or SD cards are required.

Technical Advantages

• Self-configuring system on startup
• Automated verification simplifies charging and airflow procedures, and automatically goes through all modes of operation to verify the system is operating properly and within specifications
• New sensors to easily monitor data, with information shared wirelessly, either onsite or in the cloud
• Standardized and consistent wiring: four-wire connection for all communicating equipment simplifies installation
• Faster, more robust communication protocol
• Remotely control connected systems from the Trane Home mobile app.
• The system supports up to four indoor temperature and humidity sensors in a non-zoned system for averaging, including ZSENS930AW00MA sensors.
• With an Internet connection, full system updates for installed communicating equipment will occur automatically.

5. Placement & Installation

5.1 Location

• Install the UX360 in a centrally located climate controlled living space with good air circulation.
• The UX360 MUST be at least 3 feet apart from any other electronic device such as a TV or speaker.
• You MUST assign an indoor temperature sensor that is installed in a controlled space. See the Sensor Setup section for details.
• If the UX360 and the SC360 must be in close proximity (closer than 3 feet), always install the UX360 diagonally above the SC360. If top left and top right sides are not possible, then install the SC360 to the right or left side of the UX360.
• Keep these 2 devices as far apart as possible. Never install them on top of each other.
• The UX360 should be at least 3 feet away from a corner where 2 walls meet. Corners have poor circulation.
• The UX360 should not be directly exposed to air currents from supply air or ceiling fans.
• Avoid exposing the UX360 to any radiant heat source such as sun light or fireplaces.
