Group objects
No.
98
This group object is enabled if the parameter Connection of an analog room control unit to physical device
input a in the Setpoint adjustment parameter window is set to No.
This group object is hidden in actuator mode.
The group object transmits a setpoint change between the controller (master) and the slave or any other de-
vice. This group object can adjust setpoints within the permitted limits (see parameters Max. manual increase
in heating mode via KNX, Page 293, Max. manual reduction in heating mode via KNX, Page 294, Max. man-
ual increase in cooling mode via KNX, Page 294, Max. manual reduction in cooling mode via KNX,
Page 294).
The group object's data point type depends on the data point type selected in the parameter Manual setpoint
adjustment via KNX with in the Setpoint adjustment parameter window.
The type of DPTs used can be selected to ensure usability of setpoint adjustment with other devices as well.
DPT 6.010 must be selected for existing systems and for ABB devices that do not use the current controller
version (ClimaECO master/slave concept) yet. With this method, the temperature is converted to an integer
value before it is sent and the adjustment is transmitted in steps.
With newer devices, the DPTs 9.001 or 9.002 can be selected for the purpose of absolute or relative setpoint
adjustment via temperature values.
The setpoint temperature (e.g. 22 °C) or the change in the setpoint temperature (z.B. +2 °C) must be sent to
the group object for this purpose.
All ABB devices still support adjustment via DPT 6.010.
If the required temperature is outside the permitted setpoint range, the maximum/minimum possible value will
be set. For this purpose, the master device checks the received value and returns the set value via the group
object Confirm setpoint adjustment (master).
If a slave is used:
This group object must be connected to the corresponding group object of the slave for master/slave
operation to function.

This group object is enabled if the device was parametrized for actuator mode and the parameter Connection
of an analog room control unit to physical device input a is set to Yes in the Setpoint adjustment.
The group object sends a setpoint change of the analog room control unit connected to the actuator to the
controller.
The group object's data point type depends on the data point type selected in the parameter Manual setpoint
adjustment via KNX with in the Setpoint adjustment parameter window.
The type of DPT used can be selected to ensure usability of setpoint adjustment with other devices as well.
DPT 6.010 must be selected for the existing systems and for ABB devices that do not use the current con-
troller version (ClimaECO master/slave concept) yet. With this method, the temperature is converted to an in-
teger value before it is sent and the adjustment is transmitted in steps.
With newer devices, the DPTs 9.001 or 9.002 can be selected for the purpose of absolute or relative setpoint
adjustment via temperature values. The setpoint temperature (e.g. 22 °C) or the change in the setpoint tem-
perature (z.B. +2 °C) must be sent to the group object for this purpose.
All ABB devices still support adjustment via DPT 6.010.
