Dependent Parameter
Use control value for fan automation
This parameter is only visible if the
Free configuration
option has been selected for the
Basic-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.

Dependent Parameter
Control value direction
This parameter is only visible if the
Via group object
option has been selected for the
Actuate
basic-stage cooling via
parameter in the
Application parameters
parameter window.
Options:
Normal
Inverted
This parameter is used to specify the control value direction if it is only output via a group object.
The setting is used to actuate NC (normally closed) or NO (normally opened) valves.
If one of the physical device outputs is used to output the control value, this parameter is not dis-
played because this setting is then made in the related output stage.
•
Normal
: The control value is output normally.
Control value On/100 % => telegram value On/100 %
Control value Off/0 % => telegram value Off/0 %
•
Inverted
: The control value is output inverted.
Control value On/100 % => telegram Off/0 %
Control value Off/0 % => telegram On/100 %
