2.6 Manual operation
Function of manual operation
Manual operation facilitates on-site operation of the device. Manual operation is enabled as standard and
can be switched on and off using the Manual operation button .
Switching on manual operation:
Press the button until the yellow LED lights continuously.
Switching off manual operation:
Press the button briefly. The yellow LED continues to flash for 2 seconds.
After connection to the KNX, an ETS download or ETS reset, the device is in KNX operation. The LED
is off. All LEDs indicate the current state.
If Manual operation is generally disabled or is disabled via communication object Block manual
operation, the LED flashes during the button push.
A switchover from KNX operation to the Manual operation mode does not occur.
If manual operation is activated, the current fan speed remains set and can only be operated manually.
Here any limitations, forced operations and programmed dwell times are not considered.
If manual operation is deactivated, the fan sets to a speed to which it would also be set without manual
operation, e.g. via the value of the communication objects. The setting occurs with the parameterized
dwell times.
