Capacity code of indoor and outdoor units
For the indoor unit, the capacity code is decided at each capacity rank. (Table 1)
The capacity codes of the outdoor units are decided at each capacity rank. The maximum number of connectable
indoor units and the total value of capacity codes of the indoor units are also decided. (Table 2-1, Table 2-2)
NOTE
Compared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable
indoor units differs based on the height difference between the indoor units.
When the height difference between the indoor units is 49 ft (15 m) or less: Up to 200% of the capacity code
(Equivalent to HP) of the outdoor unit.
When the height difference between the indoor units is over 49 ft (15 m): Up to 105% of the capacity code.
If MMU-UP
H is include in the system, total indoor capacity code must be between 50% and 105% of
outdoor unit capacity.
Min.
thickness
If the system diversity is more than 135%, check the maximum number of indoor unit connections in table 2-1,
of
2-2, and then turn on DIP switch 3 of SW103 on the interface P.C. boards.
