Dependent Parameter
Use control value for fan automation
This parameter is only visible if the
Free configuration
option has been selected for the
Additional-
stage cooling
parameter in the
Application parameters
parameter window.
Options:
No
Yes
This parameter can be used to specify whether the control value for this stage is also to be used
as the control value for the fan automation.
•
No
: The control value is not used for the fan automation
•
Yes
: The control value is used for the fan automation. If this stage is active and the fan is in the
automatic mode, the control value is also used as a control value to actuate the fan.
Note
If the related stage has a free configuration, the device does not know whether the stage actu-
ated is a fan coil unit or not. However, because the fan automation only makes sense for the fan
coil unit stages, an assignment must be made here.
If a free configuration is selected for all 4 control stages and none of the stages is also parame-
terized for fan automation, the fan automation remains without function.
