Group objects
No.
103
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 change in the fan speed between the controller (master) and the slave or any
other device.
The group object's data point type depends on the data point type selected in the parameter Manual fan
speed adjustment via KNX with in the Setpoint adjustment parameter window.
The type of DPT used can be selected to ensure usability of fan speed adjustment with other devices as well.
DPT 5.010 must be selected for existing systems and for ABB devices that do not use the current controller
version (ClimaECO master/slave concept) yet. The fan speed adjustment is transmitted in steps with this
method.
DPT 5.001 can be selected on newer devices, and the fan speed thereby can be transmitted directly as a
percentage.
All ABB devices still support adjustment via DPT 5.010.
It might not be possible to set the required fan speed if limitations were activated for the fan.
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.
103
This group object is enabled if, in actuator mode, the parameter Connection of an analog room control unit to
physical device input a in the Setpoint adjustment parameter window is set to Yes.
This group object is hidden in controller mode.
When an analog room control unit is connected, this group object establishes communication between the
actuator and the controller. The analog room control unit can adjust the fan speed in this mode. The adjust-
ment is then transmitted to the controller via this group object.
This group object requests changing to a certain fan speed.
The group object must be connected to the controller's (master's) group object of the same name for this pur-
pose.
104
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 change in the fan speed between the controller (master) and the slave or any
other device.
The controller (master) uses this group object to inform the connected devices whether the requested fan
speed is permitted or to inform them about the current fan speed.
Refer to group object 100 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.
