Parameter setting
Sensor KNX AQS/TH-UP Touch
• Version: 23.10.2018 • Technical changes and errors excepted.
During initial commissioning, a threshold value must be defined, which will be valid
until the first communication of a new threshold value. For units which have already
been taken into service, the last communicated threshold value can be used. Basically,
a range is specified in which the threshold value can be changed (object value limit).
A set threshold value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and
will be available once the power supply is restored.
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.
Threshold value setting using
Parameter •
Communication objects
The value communicated last shall be
maintained
• never
• after power supply restoration
• after power supply restoration and
programming
Start threshold value in 0.1°C
valid until first communication
0 … 5000; 1200
Limitation of object value (min)
in ppm
0…5000
Limitation of object value (max)
in ppm
0…5000; 2000
Type of threshold value change
Absolute value • Increase/Decrease
Increment in ppm
(upon increase/decrease change)
1 • 2 • 5 • 10 • 20 • ... • 200
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 first 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 first communication)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
