Installation
1. Set the thermostat to idle and turn off all power to the HVAC system.

see Splitting a Port.
4. Route the Link cable out of the blower compartment through the thermostat wiring hole.
5. Close the blower compartment door.
6. Use the included wall bracket and anchors (if applicable) to mount the Link control unit on a nearby
wall. Ensure the buttons are accessible and LEDs are visible. Do not mount the Link anywhere on the
HVAC system.
7. Connect the Link cable to the Link control unit.
8. Restore power to the HVAC system.

11. Add the Link to the network (see Adding the Link to the Network).
12. Press the Network button for 10 seconds to check for network communication. The Network LED will
blink fast for several seconds while testing and go solid when the test is completed successfully. If the
test fails, the Network LED will blink slowly for one minute. See The Link is not Communicating with the
hub or controller for more information.
Adding the Link to the Network
TIP: For best results, we recommend bringing the hub or controller into the area where the Link is
installed.
1. Put the hub or controller in ADD mode. Refer to controller documentation for more information.
2. Press the Network [Insert Radio Icon] button on the Link to begin the ADD process. The
NETWORK light will begin blinking slowly.
3. After the Link is successfully added, the NETWORK light will turn solid. If the NETWORK light
is not solid after the add process, repeat steps 1 and 2.
