Do the following to make the connections from the actual thermostat
wire to the connector.
Note: These connectors are necessary for the Outdoor unit, Indoor
unit and Distribution board.
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. If a 18 ga. Thermostat wire gets
broken off inside of the connector, the connector will need
replaced.
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.
This 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.
N N o o t t e e : : This connector should be removed when using
this unit in clii mode.
