Description
The
Sensor KNX AQS/TH-B-UP
measures CO
2
concentration, temperature and
humidity and calculates the dew point. The sensor can receive external measured
values via the bus and process them with the own data to overall values (mixed values,
e. g. room average). The
KNX AQS/TH-B-UP
offers two push buttons that may be
used for changing the ambient temperature (target value), for switching between
operating modes or as free programmable bus push buttons.
The
KNX AQS/TH-B-UP
provides 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.
Integrated PI controllers allows for control of a ventilation (depending on CO
2
concentration and air humidity) and a heating/cooling system (depending on
temperature). The
KNX AQS/TH-B-UP
can emit a warning to the bus as soon as the
area of optimum comfort (according to DIN 1946) is left.
The integrated display shows the own values and data received from the bus (e.g. date,
time). 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, of
temperature
and
air
humidity
(absolute and relative), calculation of the dew point
•
Mixed values
from own measured values and external values (proportions
can be set in percentage)
•
Display
1-3 rows (own values or values received from the bus) or display of
temperature control (see
Mode display and manual temperature controller
•
2 push buttons
. Configuration as bus push button or for changing ambient
temperature and switching between operating modes (see
•
PI controller for heating
(one or two step) and
cooling
(one or two step)
depending on temperature. Control according to separate target values or
basic target temperature
•
PI controller for ventilation
depending on humidity and CO
2
concentration:
dehumidification/humidification (one step) or dehumidification (one or two
step)
•
Threshold values
can be adjusted per parameter or via communication
objects: 3 × temperature, 2 × humidity, 4 × CO
2
•
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)
