Note:
*1. If the operational capacity of indoor units is more than 130%, low airflow operation is enforced in all the indoor units. Field setting now exists to
configure this situation. For cooling and heating mode – see below.
*2. 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%.
*3. It is permitted to use a maximum connection ratio of 130% in some circumstances – please contact your local Daikin representative for further
details.
*4. For indoor units used for cooling only (do not connect to Branch Selector unit when using for heat recovery), total capacity index must be 50%
or less than the capacity index of the outdoor units.
