This group object sends the control value for additional-stage heating on the bus (ABB i-bus® KNX).
The data point type depends on the option selected in the parameter
and the associated control type. A control type is preset depending on
the option. Any control type can be selected if the option
Free configuration
is selected.
Output is via a 1-bit value (DPT 1.001) for the following control types:
•
2-point 1 bit (On/Off)
•
PI PWM (On/Off)
Telegram value:
•
1 = On
•
0 = Off

This group object sends the control value for basic-stage cooling on the bus (ABB i-bus® KNX).
The data point type depends on the option selected in the parameter
Basic-stage cooling [controller]
and the associated control type. A control type is preset
depending on the option. Any control type can be selected if the option
Free configuration
is selected.
Output is via a 1-byte value (DPT 5.001) with the following control types:
•
2-point 1 byte (0/100 %)
•
PI continuous (0 … 100 %)
•
PI continuous (0 … 100 %) for fan coil
Telegram value:
•
0 … 100 %
Note
If DPT 5.001 (percentage) is used for the activation, the value displayed for the group object may vary from the actual value due to rounding differences. The actual
value of the group object can be seen by viewing the hexadecimal value (e.g. 0x0001) or by changing to a different DPT (e.g. DPT 5.005) in the ETS.
