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 239 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%.
For indoor units used for cooling only (do not connect to Branch Selector unit
when using for heat recovery), total capacity index of cooling only indoor units
must be 50% or less than the total capacity index of the outdoor units.
