7.5.1.7.1.2.4 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 heating parameter in the Application parameters parameter window.
Options:
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.
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.

7.5.1.7.1.2.5.1 Dependent Parameter
Control value direction
This parameter is only visible if the Via group object option has been selected for the Actuate
additional-stage heating via parameter in the Application parameters parameter window.
Options:
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 Off/0 %
Control value Off/0 % => telegram On/100 %
• Inverted: The control value is output inverted.
Control value On/100 % => telegram Off/0 %
Control value Off/0 % => telegram On/100 %
