Group objects
No.
40
The group object is enabled if Deactivated was not selected for the parameter Basic-stage cooling in the
Application parameters parameter window.
This group object is hidden in actuator mode.
The group object data point type depends on the selected application and the associated control.
Output is via a 1-byte value (DPT 5.001) when the following control types are selected:
•
2-point 1 byte (0/100%)
•
PI continuous (0...100 %)
Output is via a 1-bit value (DPT 1.001) when the control types are selected:
•
2-point 1 bit (On/Off)
•
PI PWM (On/Off)
The control type is preselected by the parameter Basic-stage cooling in this case.
A certain type of control is preset depending on the selected application. The control type is freely selectable
if Free configuration is selected in this parameter.
This group object outputs the control value for Basic-stage cooling.
Use of a physical device output (e.g. valve) for basic-stage cooling:
•
The group object contains the control value that the controller uses to control the output.
Basic-stage cooling is controlled only via group object (no internal use):
•
The group object sends the control value for controlling a different actuator.
Depending on the input group objects of the actuator, it could be necessary to change the output of the control value
between 1 byte and 1 bit. This is performed via the parameters described above.
Cyclical sending and sending on a change in the control value can be set in Extended settings in the Temperature controller
– Basic-stage cooling parameter window.
