Parameter setting
Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D
• Version: 10.09.2018 • Technical changes and errors excepted.
Set the
hysteresis
independent of the type of threshold value specification.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.
Block
The switching output can be blocked using an object.
If the block is activated, define specifications here for the behaviour of the output when
blocked.
Threshold value setting via
Parameter •
Communication objects
Start threshold value in 0.1°C
valid until first communication
-300 … 800; 200
Object value limit (min)
in 0.1°C
-300…800
Object value limit (max)
in 0.1°C

Type of threshold value change
Absolute value • Increase/decrease
Increment
(upon increase/decrease change)
0.1°C • ... • 5°C
Hysteresis setting
in % • absolute
Hysteresis in 0.1°
0...1100; 50
Hysteresis in % of the threshold value
0 … 50; 20
When the following conditions apply,
the output is
(TV = Threshold value)
• TV above = 1 | TV - hyst. below = 0
• TV above = 0 | TV - hyst. below = 1
• TV below = 1 |TV + hyst. above = 0
• TV below = 0 |TV + hyst. above = 1
Delays can be set via objects
(in seconds)
No • Yes
Switching delay from 0 to 1
(If delay can be set via objects:
valid until 1st communication)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
Switching delay from 1 to 0
(If delay can be set via objects:
valid until 1st communication)

Switching output sends
