SC360 System Controller

18-HD95D1-1C-EN 7

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.
