Dependent parameter
I-proportion
Options:
The standard value depends on the option selected in the Additional-stage heating parameter in the
Application parameters parameter window.
The I-proportion stands for the integral time in a control. The integral proportion causes the room
temperature to approach the setpoint slowly and also to reach it finally. Depending on the system type
used, the integral time may need to have different values. In principle the following applies: The more
sluggish the overall system, the larger the integral time is.

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 displayed
because this setting is then made in the related output stage.
