ABB i-bus KNX
Group objects
No.
66
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 parameter window.
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 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 (e.g. +2 °C) must be sent
to the group object for this purpose.
All ABB devices still support adjustment via DPT 6.010.

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 device. This group
object confirms a setpoint adjustment requested via the group object Request setpoint adjustment so that the new value
becomes known to the requesting device as well.
Refer to group object 95 for the various data point types. The data point type of this group object depends on the same
settings.
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.
