[3] –2 Provisionally select outdoor unit
(1) Calculate CI (Capacity Index) of the selected indoor units.
CI of VRV indoor units
CI of FXMQ15PBVJU = 15
CI of FXMQ18PBVJU = 18
CI of FXMQ36PBVJU = 36
CI of FXMQ48PBVJU = 48
Calculate the total CI of the indoor units.
Total CI = 15 × 2 + 18 × 2 + 36 × 2 + 48 × 2 = 234
(2) Provisionally select an outdoor unit based on the total CI of the indoor units
The connection ratio of REYQ-TA shall be between 50% and 130%.
As the total CI of the indoor units is 234, outdoor units from 16 ton to 38 ton are connectable.
Start from 16 ton which is the smallest outdoor unit.

(3) Confirm that the number of the connected indoor units is within the limitation.
The number of the connected indoor units = 8
The max. number of connectable indoor units of 16 ton outdoor unit = 33
