Group objects
No.
64
This group object is always visible in controller mode.
This group object is hidden in actuator mode.
The device signals whether control is active (On) or inactive (Off) using this group object.
Telegram value:
•
0: Control active (On)
•
1: Control inactive (Off)

This group object is always visible in controller mode.
This group object is hidden in actuator mode.
This group object synchronizes between the controller (master) and the slave.
This group object must be connected to the slave's group object of the same name for this purpose.
This group object transmits the setpoint to be displayed.
66
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. Using this
group object a setpoint adjustment can be made within the limits allowed (see parameter Max. manual increase in heating
mode via KNX,
via KNX,
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 (e.g. +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.
