7.12.1.1.5 Dependent Parameter
Manual setpoint 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 setpoint adjustment and Confirm setpoint adjustment.
• DPT 6.010 (meter pulses): This is the only viable option if you are using legacy ABB devices.
• DPT 9.001 (Absolute temperature value): This adjusts the setpoint as an absolute temperature
value by sending the new temperature required. Likewise, the Confirm setpoint adjustment
group object sends the new temperature as an absolute value.
• DPT 9.002 (relative temperature value): This adjusts the setpoint as a relative temperature
value by sending a target temperature change (e.g. +2 °C). Likewise, the Confirm setpoint
adjustment group object sends the new temperature as a relative value.
DPT 9.001 and DPT 9.002 temperature 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 6.010 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 target temperature via the Current setpoint group
object.
Before adjusting a setpoint with an analog room control unit, please check which setpoint adjust-
ment format the controller supports.
You can also communicate setpoint changes for implementation on other equipment via the
group objects Base setpoint, Comfort heating setpoint or Comfort cooling setpoint.
Caution! Note that changing the base setpoint also changes the Standby and Economy tempera-
tures. To prevent this, use absolute rather than relative setpoint adjustment (Setpoint manager –
Setpoint specification and adjustment). However, note that with both types of adjustment, the
parametrized maximum setpoint increase/reduction limits are no longer taken into account.
