The combination of indoor unit is to be decided that the sum of indoor unit capacity index must
be smaller than the maximum combination capacity of outdoor unit. We recommend to calculate
indoor unit capacity like below.
If you do not follow our recommendation, it will have some problems in low ambient condition
i.e. some indoor unit will not be able to heat very well in heating mode.
CALCULATION METHOD FOR THE CONNECTABLE TOTAL CAPACITY OF INDOOR UNIT
Sum up the capacity of all indoor unit, but high static duct type indoor unit capacity weights 1.3
times
1
Ex) Outdoor unit : A9UW566FA3(FM56AH)(connectable maximum capacity is 73 kBtu)
Indoor unit:
AMNH186BHA0[MB18AH],AMNH246BHA0[MB24AH],AMNH246BHA0[MB24AH]
(18 + 24 + 24) x 1.3 = 66 x 1.3 = 85.8 kBtu: this combination has a some problem
2
Out door unit: FM56AH
Indoor unit:
AMNH186BHA0[MB18AH],AMNH246BHA0[MB24AH],AMNH18GD5L0[MS18AH]
(18 + 24) x 1.3 + 18 + 72.6: this combination can be ok
