1. 1

   Turn off the main power to all units in the system at the circuit breaker.

2. 2

   Consult the installation manual to manually set unique addresses for each indoor and outdoor unit, ensuring no unit is left at the factory default (48 or 49).

3. 3

   If using auto-addressing, verify that your system is a KX2 model, as it's the only one supported.

4. 4

   Restore power and re-attempt addressing if necessary. If issues persist, contact a professional.
