3.4. SHUTTER / BLINDS
3.4.1. Description
The KNX universal interface makes it possible to
control blinds and shutters with one or two buttons.
Shutter/Blinds with one button: You can both raise
and lower the blind with a single push-button. Each
short press will send a value following this
sequence “down”, “start”, “up” and “stop”. The
current direction of movement of the blind, or the
direction of the slat adjustment, always depends on
the previous action. The object value can be update
via the bus line thus there is an status object, which
prevent any incorrect behaviour. This object must
be connected with the state of the actuator via a
group address.
Shutter/Blinds with two buttons: Two inputs are
necessary for this option. With the combination of
both push buttons, the blind can be lowered or
raised with a long push button action, while a short
push button action ends the movement or adjusts
the slats by one step. The minimum period for
detecting a long push button action is
parameterized previously. Each input providing the
function of one push button defined as “Up” or
“Down” through the parameter “Direction” . One
input configured as “Up” will send Up and start
telegrams while another configured as “Down” will
send down and stop telegrams.
