Parameter setting
Sensor KNX AQS/TH-B-UP
• as of software 3.1 • Version: 01.03.2017 • Technical changes and errors excepted.
Note:
if an external portion is used, all of the following settings (threshold values, etc.)
are related to the overall reading!
The
minimum and maximum readings
can be saved and sent to the bus (maximum
value only for CO2). |||Use the "Reset temperature (and/or humidity, CO
2
) min/max. val-
ue" objects to reset the values to the current readings.
Note:
The values are not retained after a reset.
5.4.
Threshold values: Temperature, humidity,
CO2
Activate the threshold values that you want to use here. The
Sensor KNX AQS/TH-B-
UP
provides three threshold values for temperature, two threshold values for air hu-
midity and four threshold values for carbon dioxide.
Table of CO2 values:
1000 ppm corresponds to 0.1% CO2 content.
5.4.1. Threshold value 1, 2, 3, 4: Temperature, humidity,
CO2
The settings options for temperature, humidity and CO2 threshold values are the same.
Threshold value
Set the threshold values directly in the application program using parameters, or de-
fine them via the bus using a communications object.
