Startup time
This time defines when the unit "restarts" after a restart (reset, reprogramming, bus voltage
recovery). This can be important when - Example 1 - a bus reset is carried out. If there are many units
on a line, all units would start at the same time and load the bus. With a variable time, the units can
start differently.
Example 2: If the Time/Date, Status/Values for toggle or Day/Night object are requested, it makes
sense that the devices responsible for them start up first, and the Blind Push Button only a little later.
This ensures that all values are available and correct.
Important
: + 10s delay on the device start-up time for the time switch (lock, switching times etc.).
„Operation“
The "operation" telegram is used to show on the bus that the unit is "alive". If activated, an ON
telegram is sent cyclically.
Value for Day/Night
The polarity for Day/Night is set here. Regardless of this polarity, the unit always starts in Day mode
after reprogramming.
Polarity Shading
The polarity is defined here, whether the Shading is to be locked or enabled with a "1". This affects
the symbol in the display. At the same time, make sure that the same polarity is selected on the
shutter actuator.
Language Display
The language affects, among other things, the display of texts in the settings menu and in the table
for setting the switching times.
