Troubleshooting
Unsuccessful ComfortBridge Communication:
If the Power LED is off and the System LED blinks slowly, initial ComfortBridge communication was
unsuccessful. The System LED will blink slowly for one minute before the device performs a self-reset
and reattempts communication. Wait for the Power LED to go solid before proceeding.
Unsuccessful Test:
Pressing the Test button once calls for the fan to turn on for one minute. If this does not occur, it indicates
the Link cannot communicate with the HVAC system, or the HVAC system is not functioning properly.
1. Verify the Power LED on the Link control unit is solid. If it is not, see Unsuccessful
ComfortBridge Communication
2. Ensure the HVAC system is fully powered
3. Check for error codes reported on the HVAC system

will blink fast while the test occurs and go solid if the test is successful.
If the test is unsuccessful, the Network LED will blink slowly for one minute before automatically retrying
the test. The Link will reattempt the test 10 times until successful. If network communication is still
unsuccessful:
