Description

Indoor Sensor KNX AQS/TH

• Date of issue: 13.10.2011 • Subject to technical changes. Errors excepted.

1. Description

The

Indoor Sensor KNX AQS/TH

measures the room CO

2

concentration, the tempe-

rature und air humidity and calculates the dew point. The sensor can receive external
values for temperture, humidity and CO

2

via the bus and process them with the own

data to overall values (mixed values, e. g. room average).

The

KNX AQS/TH

provides eleven switching outputs with adjustable threshold valu-

es. The switching outputs and further communication objects can be linked by AND
and OR logic gates. Additionally, an integrated actuating variable comparator can com-
pare and output values that are received via communication objects.

Integrated PI controllers allows for control of a ventilation (depending on CO

2

concen-

tration and air humidity) and a heating/cooling system (depending on temperature).
The sensor can can emit a warning to the bus as soon as the area of optimum comfort
(according to DIN 1946) is left.

Functions:

•

Measurement of

CO

2

concentration

of the air, of

temperature

and

air

humidity

(absolute, relative), calculation of the dew point

•

Mixed values

from own measured values and external values (proportions

can be set in percentage)

•

PI controller for heating

(one or two step) and

cooling

(one or two step)

depending on temperature

•

PI controller for ventilation

depending on humidity and CO2 concentration:

dehumidification/humidification (one step) or dehumidification (one or two
step)

•

11 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

avarage values. Each with 5 inputs (for values received via communication
objects)

Configuration is made using the KNX software ETS. The

programme file

(format VD),

the data sheet and the manual can be downloaded from the Elsner Elektronik home-
page on

www.elsner-elektronik.de

in the “Service” menu.

1.0.1. Measurement of carbon dioxide in the air

The CO

2

concentration in the air is indicated in parts per million (ppm). 1000ppm cor-

respond to 0.1%. From this value on humans perceive the room air as „used“.
