Link Systems
• Installation.
Trane and American Standard
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
• SC360 controls all system decisions, and has Temperature and Humidity sensing capabilities as well as Wi-Fi and BLE communications on-board.
• Remotely control connected systems from the Home mobile app.
• The system supports up to four indoor temperature and humidity sensors in a non-zoned system for averaging, including
ZSENS930AW00MA sensors.

5.2 Network Connections
To take advantage of the full range of features on the SC360, it should be connected to the
Internet using a wireless connection.
If the SC360 will be connected to the Internet using the built-in wireless feature, choose a mounting location that ensures adequate signal strength from the wireless router.
Tips to Help Maximize Signal Strength:
• Mount the SC360 within 30 feet of the wireless router.
• Install the SC360 with no more than three interior walls between it and the router.
• Install the SC360 where electromagnetic emissions from other devices, appliances, and wiring cannot interfere with the wireless communication.
• Install the SC360 in open areas, not near metal objects or near structures (i.e. doors, appliances, entertainment centers or shelving units).
• Install the SC360 further than two inches away from any pipes, duct work or other metal obstructions.
• Install the SC360 in an area with minimized metal obstructions and concrete or brick walls between the SC360 and the wireless router.
Refer to the UX360 User Guide for additional information on connecting to the Internet.

5.4 Wiring
For ease of installation, the SC360 comes with a
CAN connector pack and has two wiring options.
There is a wire connector located in the middle, back of the unit and another one at the front, bottom of the unit.
When installing the SC360 using the wall Subbase and back connector, follow the steps below. The instructions in Section 5.5 are for the CAN connector pack and use with the
SC360 bottom connector only.
1. Adjust the length and position of each wire to reach the proper terminal on the connector block of the Sub-base. Strip 1/4” of insulation from each wire. Do not allow adjacent wires to short together when connected. If stranded thermostat cable is used, one or more strands will have to be cut to allow the cable to fit connector. For use with solid conductor 18 ga. thermostat wire.
2. Match and connect control wires to the proper terminals on the connector block.
Refer to the Field Wiring Connection
Diagrams shown later in this document.
3. Push excess wire back into the wall and seal the hole to prevent air leaks.
NOTE: Air Leaks in the wall behind the
SC360 can cause improper operation.
4. Attach the SC360 to the Sub-base.
5. Turn ON power to the heating and cooling equipment.
5.5 Trane & American Standard Link Low Voltage Wire Connectors
Link mode uses simple connectors for low voltage connections. These connections are color coded which makes the installation easier and quicker.
Wire Colors
R
DH
DL
B
Red
White
Green
Blue
Do the following to make the connections from the actual thermostat wire to the connector.
NOTE: These connectors are necessary at the communicating outdoor unit, communicating indoor unit, distribution board(s), system controller and communicating accessories.
1. Strip the Red, White, Green and Blue thermostat wires back 1/4”.
2. Insert the wires into the connector in the correctly colored locations.
3.
When you feel it release, allow each wire to slide in further.
4. Pull back on the wires individually and slightly and check if the wires are seated properly. If each wire does not pull out for all four wires, the connection is complete.
5. Connectors are ONE-TIME-USE ONLY. If the thermostat wire gets broken off inside of the connector, the connector must be replaced. If a wire color gets inserted into the wrong connector position, it may be possible to work the wire back out of the connector.
DO NOT REUSE THE CONNECTOR –
REPLACE IT INSTEAD.
6. Wire colors are for illustration purposes only.
If using a different color, ensure it lands at the correct terminal throughout all of the communicating control wiring.
Connect the CAN connector into the male coupling on the low voltage harness at the Outdoor unit.
The air handler has two dedicated CAN Connector headers on the Air Handler Control (AHC) board. In
Link communicating mode, both of them are in the communicating loop. It does not matter which one goes to the thermostat, System Controller, distribution board, outdoor unit or any other Link accessory.
