4 Description
Sensor KNX AQS/TH-UP Touch as of software 0.1.0 • Version: 23.10.2018 • Technical changes and errors excepted.
1. Description
The Sensor KNX AQS/TH-UP Touch measures CO2concentration, 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-UP Touch 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-UP Touch 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 CO2
concentration and air humidity) and a heating/cooling system (depending on
temperature). The KNX AQS/TH-UP Touch 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 device is completed with a frame of the switching series installed in the
building and thus merges with the interior.
Functions:
• Measurement of CO2concentration 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 Change ambient
temperature with the buttons)
•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 CO2concentration:
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 × CO2
•4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as
well as 16 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)

6 Installation and commissioning
Sensor KNX AQS/TH-UP Touch as of software 0.1.0 • Version: 23.10.2018 • Technical changes and errors excepted.
The product conforms with the provisions of EU guidelines.
1.1.1. Accuracy of the measurement
Measurement variations from permanent sources of interference (see chapter
Installation position) can be corrected in the ETS in order to ensure the specified
accuracy of the sensor (offset).
To ensure a correct CO2measurement, the device must be installed in a windproof
socket.
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated by the software.
2. Installation and commissioning
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• National legal regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.

7 Installation and commissioning
Sensor KNX AQS/TH-UP Touch as of software 0.1.0 • Version: 23.10.2018 • Technical changes and errors excepted.
The device may only be used as a fixed-site installation; that means only when
assembled and after conclusion of all installation and operational start-up tasks and
only in the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Installation position
The Sensor KNX AQS/TH-UP Touch is made for wall mounting in a socket
(Ø 60 mm, 42 mm deep).
May be installed and operated in dry interior rooms only.
Avoid condensation.
When selecting an installation location, please ensure that the measurement results
are affected as little as possible by external influences. Possible sources of interference
include:
• Direct sunlight
• Drafts from windows and doors
• Draft from ducts which lead from other rooms or from the outside to the
junction box in which the sensor is mounted
• Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes
• Connection lines and ducts which lead from warmer or colder areas to the
sensor
Measurement variations from permanent sources of interference can be corrected in
the ETS in order to ensure the specified accuracy of the sensor (offset).
To ensure a correct CO2measurement, the device must be installed in a windproof
socket.
Fig. 1: Sectional drawing.
The Sensor KNX AQS/TH-UP Touch fits into a standard
socket (Ø 60 mm, depth 42 mm).
The frame is not included!

2.3. Composition
2.3.1. Housing
2.4. Assembly of the sensor
First of all fit the windproof socket with connection. Also seal inlet pipes to avoid
infiltration.
Screw the base plate onto the socket and position the frame of the switching
programme. Connect the bus line +/- to the black-red plug.
Pin the housing with the notches on to the metal frame, so that device and frame are
fixed.
2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received or sent via the
bus.
