Parameter setting
Actuator KNX S1R-BA4-UP 24 V
• Version: 27.05.2020 • Technical changes and errors excepted.
When switching via communication object "Channel A1 switch" (210), the light is
turned on or off normally. When switching via object "Channel A1 staircase light
function start" (215), the staircase light time function is activated. The time function has
priority, i.e. the status triggered by normal switching is overwritten.
6.2.5. Channel settings – switch functions
If two switchable devices are connected to the output channel, two separate channels
will appear (e.g. "Channel A1 – switch function" and "Channel A2 – switch function").
First set the general specifications for the connected device and, if necessary, activate
the connections, time functions and blocking objects. A diagram is found in chapter
Correlation connection – time switch – block
6.2.5.1.Connection (switch functions)
The menu item "connection" appears only for the settings for the switch function
channel if selected "Use switch functions: Yes".
In the connection object ("Channel X connection") different communication objects can
be linked with AND or OR. E.g. a light can only be switched on if the button input is
active AND twilight is active.
