outdoor unit of every refrigerant system. Notice that in this case, the outdoor unit must be set to
automatic serching address mode. And it will be effective after about 6 minutes.
2. To connect indoor CCM controller via XYE port of indoor unit, this wiring method is suitable for
all type of indoor units, not just for new indoor units.
