Notes: ∗1. If the operational capacity of indoor units is more than 130%, low airflow operation is enforced in all the
indoor units. Refer to the table 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%.
Indoor unit fan tap setting
Indoor units fan speed limitation related to connection capacity and outdoor air temperature for energy saving.
Default value = 0
Value [2-34]
Fan speed is limited to L tap when indoor units capacity ≥ 130%.
