ABB i-bus KNX
Parameters
•
Group object: If Group object has been selected as the option, there is no actuation via any of the
internal outputs, instead the control value is only output on the bus.
The control value is output via the related Status Control value Additional-stage cooling group object.
The settings for the exact control parameters are made in the Temperature controller – Additional-stage
cooling parameter window.
The settings for the actuation of the control values via a valve output are made in the valve parameter
window.
7.4.1.3 —
Dependent parameter
Window contact input
This parameter is not visible if the Channel function parameter has been parameterized with the Actuator
channel option.
Options:
This parameter is used to inform the integrated controller whether it is to include the status of a window
(open/closed) in the control.
•
Deactivated: If Deactivated has been selected, the window status is not taken into account by
the controller.
•
Via physical device input: If this option is selected, the controller checks which of the physical device
inputs has been parameterized for a window contact. The status of the window contact connected to
this input is included in the control. The message: Configure in 'Inputs' parameter window appears.
Only device inputs that have been parameterized as a window contact are detected as such.
If no input has been parameterized as a window contact, the function is considered deactivated.
If several inputs have been parameterized as a window contact, there is a logical OR link between these
inputs. As soon as one of the contacts signals the status "Window open", the controller evaluates
the status as "Window open". Conversely, if all inputs signal the status "Window closed", the controller
evaluates the status as "Window closed".
•
Via group object: The window status is received via a group object. The dependent Window contact
group object appears. In addition, the dependent Window open when parameter is enabled.
