Manual operation

General
The outputs can be directly controlled using the buttons in manual operation.
Accordingly, the wiring of the loads connected to the outputs can be verified during commissioning. You
can, for example, ensure that the connected valve drives open or close the valves correctly. If bus voltage
is not yet available at the time of commissioning, the device can be supplied with power for manual
operation using the Power Supply NTI/Z.
Function of manual operation
Manual operation facilitates on-location operation of the device. As standard the button
operation is enabled and can be switched on and off using it.

A switchover from KNX operation to the Manual operation mode does not occur.
Important
If manual mode is activated, it has a higher priority than other functions, e.g. safety. As soon as the
output state is modified in manual mode via button Output, active functions, such as blocking, forced
operation and valve purge are interrupted and values of the characteristic curve are not considered.
Manual operation is inactive after bus voltage recovery, download or ETS reset.
Supplied state
Manual operation is enabled by default in the supplied state. The device is in KNX operation after
connection to the bus. The yellow LED
buttons for the outputs are non-functional.
Telegram processing with active manual operation
Incoming telegrams will continue to be received and saved during active manual operation. After manual
operation is deactivated, the device will update.
If a telegram with the value 1 is received via communication object Enable/block manual operation, active
