Operating controls

Buttons for manual operation are located on the front of the device.
If manual operation is activated, the current control value of the respective output is retained and the
yellow LEDs on the outputs indicate the current status (ON/OFF). A target position, which may not have
yet been achieved, is approached. The outputs can now only be operated via the manual buttons for the
outputs. The first button push switches on the output if the control value = 0. If the control value > 0, the
output is switched off. Every subsequent button push toggles the output.
The behaviour of the operating elements dependent on the operating states, KNX operation and Manual
operation is described in the following table:
Button
Manual operation
Output A...X
Reset
KNX operation
Long button operation (about 3 sec.): Switch to Manual
operation, provided that Manual operation is not blocked
by a parameter setting.
Short button push: LED Manual operation flashes and
switches off again. The device is once again in Manual
operation
No reaction
For resetting a fault, e.g. short-circuit or overload of an
output group. The button must be pushed until the red
LED switches off, for this purpose.
The button function is inactive during an ongoing short-
circuit test.
Manual operation
Long button operation (about 3 sec.): Changeover to the
KNX operation. The inputs are queried again, and the
input states are updated accordingly.
The reset of Manual operation to KNX operation can be be
undertaken in a programmable time, depending on the
parameterization.
By pressing button output A is switched on or off. A
connected valve drive opens/closes the valve.
The display indicates the current switching state of the
output.
For resetting a fault, e.g. short-circuit or overload of an
output group. The button must be pushed until the red
LED switches off, for this purpose.
The button function is inactive during an ongoing short-
circuit test.
