Function with manual operation
A target position which may not have yet been achieved is
approached. The first button push switches the target position to 0 %
if it was unequal to 0 % beforehand, and 100 % if it was unequal to
100 % beforehand. Thereafter, each push of a button toggles the
target position between 0 % and 100 %. During deactivation of
manual operation the target position is approached that would have
been set without manual operation.
With manual operation a set characteristic curve correction is not
taken into consideration.
Button function at overload
The description concerns the button HEATING
HEATING .
The device is in the KNX operating state and the output of the
HEATING valve has a malfunction, e.g. due to an overload.
The valve HEATING LED flashes with a frequency of five hertz to
indicate the malfunction. At the same time the communication object
Overload Valve HEATING sends the value 1. With the respective
valve HEATING button the fault is acknowledged and the
communication object Overload Valve HEATING is reset to the value
0. In order to acknowledge the fault with the valve HEATING button,
the button must be pressed for longer than four seconds.
If the fault continues to persist after acknowledgement, the valve
HEATING button indicates it by flashing (five hertz). The communication
object Overload Valve HEATING is set again to the value 1.
Note
If the device is in Manual operation the acknowledgement function
Overload is not available.
