RXYQ72XA, RXYQ72XB: 70%
If the operational capacity of indoor units is more than 130%, low airflow
operation is enforced in all the indoor units. This limitation can be deactivated
through field setting. Refer to page 188 for detail.
When outdoor-air processing units (FXMQ-MF) and standard indoor units are
connected, the total connection capacity of the outdoor-air processing units
(FXMQ-MF) must not exceed 30% of the capacity index of the outdoor units. And
the connection ratio must not exceed 100%.
Regarding the combinations related to the low-temperature hydrobox (HXY-TA),
refer to the service manual SiUS392016EA. Low-temperature hydrobox can only
be connected to single module outdoor units.
