7.12.1.1.6 Dependent Parameter
Manual fan adjustment via KNX with
This parameter is only displayed if you select No when setting Connect analog room control unit to
physical device input a.
Options:
This parameter determines the datapoint type used to adjust the setpoint via group objects
Request fan speed adjustment and Confirm fan speed adjustment.
• DPT 5.001 (percentage value): Selecting this DPT sends the fan adjustment as a 0...100%
value. To adjust the fan speed, simply enter the new required value as a percentage.
• DPT 5.010 (meter pulses): This is the only viable option if you are using legacy ABB devices
that do not yet support the latest version of the master/slave concept. It is the only way to en-
sure that the master and slave can communicate. This option sends the fan adjustment as a
proprietary value.
DPT 5.001 fan adjustment will not work on legacy ABB devices that do not yet support the latest
version of the master/slave concept. For these devices, DPT 5.010 is the only option, which
means that other equipment (such as display systems) cannot read the setpoint adjustment.
However, they can read or display the current fan speed via the Status Fan speed group object.
You also have the option to adjust the fan speed at any time with the Switch fan speed group ob-
ject.

7.12.1.1.7 Dependent Parameter
Reset manual adjustment via KNX when base setpoint received
This parameter is only displayed if you select No when setting Connect analog room control unit to
physical device input a.
Options:
Selecting Yes when setting this parameter resets manual setpoint adjustment when a value is re-
ceived via the Base setpoint group object.
Selecting No adds the manual setpoint adjustment to the new setpoint when a value is received via
the Base setpoint group object.
Example:
Old base setpoint 21 °C + manual adjustment 1.5 °C = 22.5 °C. Group object receives a new
base setpoint of 18 °C + previous manual adjustment of 1.5 °C = 19.5 °C.
