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.
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
Indoor unit fan tap setting
0
Fan speed is limited to L tap when indoor units capacity ≥ 130%.
1
In heating mode, fan speed is limited to L tap when indoor units capacity ≥ 130%.
2
Fan speed follows a setting of the remote controller (not limited by indoor units connection capacity).
3
Fan speed is limited to L tap when outdoor air temperature goes down to below 85.1°F (29.5°C) and indoor air
temperature is in condition A (*). It returns to remote controller setting when outdoor air temperature goes up to over
90.5 °F (32.5°C) or indoor air temperature is in condition B (**).
4
Fan speed is limited to L tap when outdoor air temperature goes down to below 74.3°F (23.5°C) and indoor air
temperature is in condition A (*). It returns to remote controller setting when outdoor air temperature goes up to over
79.7°F (26.5°C) or indoor air temperature is in condition B (**).
5
Fan speed is limited to L tap when outdoor air temperature goes down to below 66.7°F (19.3°C) and indoor air
temperature is in condition A (*). It returns to remote controller setting when outdoor air temperature goes up to over
72.1°F (22.3°C) or indoor air temperature is in condition B (**).
6
Fan speed is limited to L tap when outdoor air temperature goes down to below 85.1°F (29.5°C). It returns to remote
controller setting when outdoor air temperature goes up to over 90.5°F (32.5°C).
7
Fan speed is limited to L tap when outdoor air temperature goes down to below 74.3°F (23.5°C). It returns to remote
controller setting when outdoor air temperature goes up to over 79.7°F (26.5°C).
8
Fan speed is limited to L tap when outdoor air temperature goes down to below 66.7°F (19.3°C). It returns to remote
controller setting when outdoor air temperature goes up to over 72.1°F (22.3°C).
* Indoor condition A: Temperature difference (indoor air temperature - set temperature) is more than -2.7°F (-1.5°C) and less than 5.4°F (3°C).
** Indoor condition B: Temperature difference (indoor air temperature - set temperature) is -2.7°F (-1.5°C) or less, or 5.4°F (3°C) or more.
