3 Description
Ventilation Control AQS/TH PF • Version: 31.01.2017 • Technical changes and errors excepted.
1. Description
The Ventilation Control AQS/TH PF combines sensor system and control
technology for the ventilation system. Temperature, humidity and CO2 level of the air
are monitored. The device controls a window (open/close in one or two steps) or a
ventilation device (one or two levels) via potential-free outputs.
Two inputs allow an interruption of the automatic system via external signals. A
continuous movement command from a connected hand-held device, a timer or a
blocking function (rain detector or similar) takes precedence.
The housing fits into standard 55 mm switching programmes and is available in two
different colours. The AQS/TH PF is equipped with two buttons for manual control of
the respective window/ventilator and for adjusting the device. The display shows
current measured values and mode and guides through the set-up menus.
Functions:
• Measuring the CO2level in the air, the temperature and relative air
humidity
•Control of a window of ventilator in one or two steps, threshold values to
be adjusted individually
•Display of current measuring values and mode
•2 buttons for adjustment and manual control
•2 inputs for external actuation commands (button, timing, rain detector/
blocking function) with priority in case of continuous signal

* Please note the information on measuring accuracy below.
The product conforms with the provisions of EU directives.
1.1.1. Measuring accuracy
Follow the instructions in chapter Installation position to avoid sources of interference
and to ensure the specified accuracy of the sensor. To ensure a correct CO2
measurement, the device must be installed in a windproof socket.
The indicated accuracy of the CO2measurement will be achieved after a run-in
period of 24 hours (without interruption of the bus voltage) if the sensor has been in
contact with fresh air (350…450 ppm) at least once in this period. During the warm-up
phase the reading may not be displayed at all or wrongly, or remain frozen at 2001.
After this, the CO2sensor will recalibrate every two weeks by defining the lowest
measured value captured during that period (without interruption of the bus voltage)
as a reference for fresh air.
The guarantee the accuracy on a sustained basis, the sensor should be provided with
fresh air at least once in two weeks. This occurs normally during room ventilation.
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated by reducing the measured temperture by the
self-heating of 0.7°C. The indicated indoor temperature measured value approches the

temperature can be adjusted in the basic settings menu.
2. Installation and start-up
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.
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 location
The Ventilation Control AQS/TH PF are installed flush to the wall surface in a
junction box (R 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
6 Installation and start-up
Ventilation Control AQS/TH PF • Version: 31.01.2017 • Technical changes and errors excepted.
• 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 such sources of interference must be corrected in the
basic settings menu in order to ensure the specified accuracy of the sensor.
To ensure a correct CO2measurement, the device must be installed in a windproof
socket.
