Additional parameters for dual-surface dimming
These are used to dim either brighter or darker and to
either switch on or off using a single key. Therefore,
you must set the parameters for a second key (second
input) for the opposite direction.
You can set whether a stop telegram is to be transmit-
ted when the key is released. When you have enabled
the transmission of a stop telegram, a stop telegram
will be sent via the 4-bit dimming object after prolon-
ged activation of the key, thus terminating the dim-
ming procedure in the dimming actuator.
A single command is sufficient to cycle through the
dimming range. This dimming procedure can be used
for most applications. The other possible dimming
steps (1/2 - 1/64 brighter or darker) dim brighter or dar-
ker by the selected step. For example, to dim from
min. to max. brightness, you would need to push the
key for a prolonged period four times in succession if
the level set is 1/4.
"Dimming direction" parameter value for dual-surface
dimming:
– brighter
– darker
Communication objects
You can select the following communication objects:
Per input:
You can use the blind control function to do the follo-
wing:
– move the blind using an individual key and adjust
the slats (single-surface blind operation).
– With the blind control function, you can raise the
blinds / adjust the slats using a single key and lower
the blinds / adjust the slats using a second key (dual-
surface blind operation).
– Move the blind to a pre-specified position.
– Move the blind between two previously specified
positions.
Blind control function up or down with one key in
each case (dual-surface blind operation)
After the corresponding key is pressed for a short ti-
me, a stop/step telegram will be transmitted; after the
key is activated for a prolonged period (the parameters
for the exact period can be set), a movement telegram
will be transmitted. With this function, you must set
the parameters for a second key (second input) with
the corresponding settings for the blind movement in
the opposite direction. Both keys (inputs) must be gi-
ven the same group addresses.
Blind control function up or down with a single key
(single-surface blind operation)
The current direction of movement of the blind, or the
direction of the slat adjustment, always depends on
the previous action, i. e. when the blind has just been
moved downwards, it will move upwards the next
time the key is activated for a long period (parameters
for the period can be set).
After a stop/step telegram has been transmitted to ad-
just the slats, a stop/step telegram for the same direc-
tion of movement can be created by pressing the key
again, as long as this subsequent push-button action is
carried out within a time period, the parameters for
which can be set. If this time period has elapsed, the
direction of rotation of the slats will change when the
key is pressed briefly.
