On a long press: a move-up order will be sent if the last short press
caused a step-down order or if the current position is found to be 100%.
On the other hand, a move-down order will be sent if the last short
press caused a step-up order or if the current position is found to be
0%.
As usual in the KNX standard, stop/step orders are interpreted by the
actuators as a request to move the slats one step up or down (in case the
shutter is still) or as a request to interrupt the motion of the shutter (in case it
is already moving up or down).
Flat / Flat 55 are aware of the current position of the shutter through a
specific object which should be linked to the analogous object of the shutter
actuator in order to receive feedback.
Hold & Release: the device will send an order to move the shutter when
the button is touched, and the order to stop it as soon as it is released.
Hence, short or long touches have the same effect: the shutter will remain
in motion as long as the user keeps holding the button.
The direction of this motion (upwards or downwards) will alternate with every
touch, according to the following sequence: downwards upwards
downwards …
However, there are some exceptions to this alternation:
If the position of the shutter is found to be 0%, the next order will lower
the shutter.
If the position of the shutter is found to be 100%, the next order will
raise the shutter.
Flat / Flat 55 are aware of the current position of the shutter through a
specific object which should be linked to the analogous object of the shutter
actuator, in order to receive feedback.
This object is initialised with value “50%” after a download or a bus failure;
therefore, the actuator is required to update it with the real value after the bus
recovery.
The “state-dependent” LED illumination mode is not available for this function.
