4. Trane®& American Standard®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.
• Verication. 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.

5.1 Location In Controlled Space
The SC360 is not required to be installed in
a controlled space. However, if the SC360
is located in a controlled space, install it in a
centrally located climate controlled living space
with good air circulation and follow the guidelines
below.
• In order for the SC360 to be assigned as an
indoor temperature and humidity sensor, it
must be installed in a controlled space.
NOTE: See the UX360 Installer Guide for
details on how to configure the SC360 for a
controlled space and assign it as an indoor
temperature and humidity sensor.
• The SC360 MUST be at least 3 feet apart
from any other electronic device such as a TV
or speaker.
• If the SC360 is not within the controlled space
you MUST assign an indoor temperature
sensor that is installed in a controlled space.
See the UX360 Installer Guide 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 SC360 should be at least 3 feet away
from a corner where 2 walls meet. Corners
have poor circulation.
• The SC360 should not be directly exposed to
air currents from supply air or ceiling fans.
• Avoid exposing the SC360 to any radiant heat
source such as sun light or fireplaces.

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 Sub-
base 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 Red
DH White
DL Green
B 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.
NOTE: For use with 18 ga. solid core thermostat wire.
