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 202 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%.
When connecting the hydrobox, to prevent temporary water temperature drop on the secondary side of the
hydrobox at the time of defrosting or when the indoor unit starts/stops, and to prevent freezing, connect the
indoor unit with 50% or more capacity of the outdoor unit.
Mixed combination of FXMQ-MF and hydrobox in the system is not allowed.
