Description
The
Air Quality Sensor KNX AQS-UP basic
measures the CO
2
concentration in the
room. The sensor can receive an external CO
2
value via the bus and process it with the
own data to an overall value (mixed value, e.g. room average).
The
KNX AQS-UP basic
provides four switching outputs with adjustable threshold
values. The switching outputs and further communication objects can be linked by
AND and OR logic gates. Additionally, an integrated actuating variable comparator can
compare and output values that are received via communication objects.
An integrated PI controllers allows for control of ventilation depending on CO
2
concen-
tration.
The housing is completed with a frame of the switching series installed in the building
and thus merges with the interior.
Functions:
•
Measurement of
CO
2
concentration
of the air
•
Mixed value
from own measured value and external value (proportions can
be set in percentage)
•
PI controller for ventilation
depending on CO
2
concentration:
dehumidification/humidification (one step) or dehumidification (one or two
step)
•
4 switching outputs
with adjustable threshold values (Threshold values can
be set by parameter or via communication objects)
•
8 AND and 8 OR logic gates
with each 4 inputs. Every switching incident as
well as 8 logic inputs (in the form of communication objects) may be used as
inputs for the logic gates. The output of each gate may optionally be configured
as 1 bit or 2 x 8 bits
•
2 actuating variable comparators
for output of minimum, maximum or
average values. Each with 5 inputs (for values received via communication
objects)
Configuration is made using the KNX software ETS. The
product file
can be down-
loaded from the Elsner Elektronik website on

in the “Ser-
vice” menu.
