Notes
1. There is no restriction on the number of connectable ·BP· boxes.
2. ·EKEXV· kits are also considered indoor units.
3. Restrictions regarding the air handling unit capacity
4. Pair AHU = system with 1 air handling unit connected to one outdoor unit
Multi AHU = system with multiple air handling units connected to one outdoor unit
About ventilation applications
I. ·FXMQ_MF· units are considered air handling units, following air handling unit limitations.
- Maximum connection ratio when combined with ·VRV DX· indoor units: ·CR 30·%.
- Maximum connection ratio when only air handling units are connected: ·CR 100·%.
- Minimum connection ratio when only ·FXMQ_MF· units are connected: ·CR 50·%
For information on the operation range, refer to the documentation of the ·FXMQ_MF· unit.
II. ·Biddle· air curtains are considered air handling units, following air handling unit limitations:
For information on the operation range, refer to the documentation of the ·Biddle· unit.
III. ·EKEXV + EKEQ· units combined with an air handling unit are considered air handling units, following air handling unit limitations.
For information on the operation range, refer to the documentation of the ·EKEXV-EKEQ· unit.
IV. ·VKM· units are considered to be regular ·VRV DX· indoor units.
For information on the operation range, refer to the documentation of the ·VKM· unit.
V. Because there is no refrigerant connection with the outdoor unit (only communication F1/F2), ·VAM· units do not have connection limitations.
However, since there is communication via F1/F2, count them as regular indoor unit when calculating the maximum allowed number of connectable indoor units.
