• Version: 28.05.2020 • Technical changes and errors excepted.
When switching via the "Switch channel A1" (1) communication object, the light is
switched on or off normally. When switching via the "Channel A1 Staircase lighting
function Start" object (5), the staircase lighting time function is activated. The time
function has priority, i.e. the status triggered by normal switching is overwritten.
6.3.2. Linking
The "Link" menu item only appears if "Use linking functions" is selected in the settings
for the switch function channel: yes’ is selected.
In the logic object ("Channel X link"), various communication objects can be linked with
AND or OR. Z. B. a light can only be switched on if button input active AND twilight ac-
tive.
6.3.3. Switch on and off delay
The menu item only appears if a switch on or switch off delay is selected in the settings
for the switch function channel. The menu item has the same name as the selected
function.
With the switch on and switch off delay, for example, a switch for ventilation device
and light can be used. However, due to the switch on delay, the ventilator does not start
until the light has been on for a few minutes. The switch off delay causes the ventilator
to run after the switch has been pressed again and the light is already off.
