For indoor unit, the capacity code is decided for each capacity rank.
NOTE :
Capacity rank : Correspondence to Btu/h. Capacity code : Correspondence to Horsepower.
For outdoor unit, maximum No. of connectable indoor units and total capacity code of indoor units
are decided.

Capacity correction in case of frost on the outdoor heat exchanger in heating
Correct the heating capacity when frost was found on the outdoor heat exchanger.
Heating capacity = Capacity after correction of outdoor unit × Correction value of capacity resulted from frost
