•
Move (raise / lower) orders (on
long presses
).
•
Stop / Step orders (on
short presses
).
Being a one-button control, the direction of the motion will alternate
(upwards / downwards) for both the move and the step orders after every
long press. However, there are some exceptions to this alternation:
•
On a short press: a step-up order will be sent if the last long press
made the shutter move up, or if the current position is found to be
100%. On the other hand, a step-down order will be sent if the last
long press made the shutter move down or if the current position is
found to be 0%.
•
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).
Square TMD-Display is 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 as soon
as 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
