Group objects
No.
71
The group object is enabled if Deactivated was not selected for the parameter Additional-stage heating 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:
•
•
•
Output is via a 1-bit value (DPT 1.001) when the control types are selected:
•
•
The control type is preselected by the parameter Parameter Additional-stage heating in this case. A
certain type of control is preset depending on the selected application. The control type is freely se-
lectable if Free configuration is selected in this parameter.
This group object outputs the control value for Additional-stage heating.
Use of a physical device output (e.g. valve) for Additional-stage heating.
•
Additional-stage heating is controlled only via group object (no internal use):
•
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 change of the group object can be set under Extended settings in the
Room thermostat – Basic-stage heating parameter window.

Note
The group object contains the control value that the controller uses to control the output.
The group object sends the control value for controlling a different actuator.
