Parameter setting
Sensor Sewi KNX TH-L-Pr
• Version: 17.11.2016 • Technical changes and errors excepted.
Please note that object type and value for the slave's cycle reset input and the master's
cycle reset output must be set the same.
Application Example:
A person steps into a corridor, the master recognises this movement and switches on
the corridor lighting. When leaving the corridor, the person wants to switch off the light
using a switch.
However, in the meantime a second person has entered the corridor who is detected
by a slave. This person would be in darkness and would have to wait for the slave's
next transmission cycle before the light would be switched on again.
To prevent this, the switch command is connected to the "master: central off" object.
As a result, the master sends a cycle reset command to the slave if the light is switched
off manually. In the present example, the master would immediately switch the light
back on.

Light control
For light control, the
Sensor Sewi KNX TH-L-Pr
detects the brightness in the room.
Activate the light control.
Set, in which cases the
data
received via object for setpoint value, setpoint value-ac-
tual difference, dimming increment and times are to be retained. Please note that the
setting "After power supply restoration and programming" should not be used for the
initial start-up, as the factory settings are always used until the first communication.
Set the
setpoint value for the brightness in the room
and specify whether, besi-
des the dimming information defined below, a switching object should also be sent.
Specify, whether the light control
is activated by movement and/or by a start/
stop object
. For a regulation by movement, the device's internal motion detector is
analysed.
Set the object evaluation and the object value prior to the first communication. Define,
for how many seconds the regulation is to continue to run after the end of the mo-
vement.
