1 Introduction
The Querx product line comprises smart sensors that gather
and monitor temperature- and humidity-values.
This user manual will tell you how to configure, use and
maintain the network-compatible devices.
Current and further
information on the Querx range of products can be found at
www.egnite.de and sensors.egnite.de.
1.1 Safety Notes

Any other use of the devices is considered contrary to the
designated use. The manufacturer takes no responsibility for
consequences resulting out of any application that is
contrary to the designated use.
Please follow these safety
notes, in order to minimize the
risk of electrical accidents:
Only use the device, cables and power supply in faultless
condition.

1.3 About Querx
Querx sensors gather climate data and make it accessible via
network-interfaces. If limit values are exceeded, an alert
function automatically sends notifications via e-mail (TLS /
StartTLS), SNMP and Syslog.
The integrated data logger tracks the data of up to 7.5 years
in the WLAN-models (51 days for the non-WiFi models). The
gathered values are displayed in an interactive graph on the
web-interface. The data can additionally be exported in
various formats or accessed via an HTTP-interface.
Querx can be connected to the internet of things, using
cloud services, making data accessible globally via the web
and apps.
SNMP makes it possible to integrate the device into network-
management solutions, Modbus/TCP allows for the
application in industrial process control (SCADA). Status-,
error- and alert-notifications can also be forwarded to a
Syslog-server.

Introduction 9
2 First Use
2.1 Before First Use
The device should be left to acclimatize before setup, if its
temperature differs from the ambient climate.
In this case, wait for approximately two hours, before
connecting Querx to the power supply.
⚠
Attention
Temperature differences between the smart sensor and its
surroundings can lead to condensation, damaging the
device.
⚠
Information
Temperature differences between the smart sensor and its
surroundings can lead to measurement errors.
2.2 Mounting the Sensor
Querx sensors can be mounted using the latches on the
case. They can alternatively be mounted using zip-ties, for
instance tying them to piping
Please take note of the following points when mounting the
device:
Querx is designed for indoor use.
Do not mount Querx in locations that are directly exposed
to sunlight.
TH Models: The device should be exposed to a sufficient
airflow. Measurements can be made in still air, but the
results for humidity will be falsified.
Do not mount Querx with the sensor cable pointing
upward. The cable should point downward or to either
side.
First Use 10
2.3 Model PT: Connecting the Sensor Cable
The Querx PT models support 2-, 3- or 4- wire Pt100 or
Pt1000 sensors. Their color coding can vary depending on
the underlying standards.
You will require the following tools, in order to connect a
sensor.
A tool with a fine tip, e.g. an fine screwdriver or a pair of
A biro
Possibly a magnifying glass
2.3.1 Connecting a Sensor
Two dipswitches located above the terminals for the cable
cores are used to select whether the sensor is connected to
Querx PT using two, three or four cable cores.
4-core Sensor 3-core Sensor 2-core Sensor
1. The above illustrations tell you which switch position your
sensor requires.
2. Use a tool with a fine tip to set the dipswitches into the
required position. If required, use a magnifying glass.
First Use 11
3. Proceed to connect the individual cable cores to the
terminals as displayed in the images.
⚠
Information
It might be that none of the displayed cable core colors
correspond with your sensor, depending on the standard
underlying the sensor. In this case, please consult the data
sheet provided by the manufacturer.
2.3.2 Mounting Individual Cable Cores
1. Depress the fixture corresponding with the terminal to
which you want to connect the cable core.
2. Insert the core into the terminal.
3. Release the fixture.
4. Test the connection by pulling on the cable with a little
force.
In order to remove the cable, depress the fixture again and
pull the cable out.
2.4 Establishing the Network Connection
Connect Querx to your network or directly to the computer
you intend to use to configure the device, using a network
cable.
First Use 12
2.5 Power Supply
1. Prepare the power supply by inserting the plug that is
used in your country. An audible click indicates that the
connection has been made.
2. Connect Querx to the power supply using a micro-USB
cable.
3. Plug the power supply into a socket. The Querx status-
LED will now light up yellow.
⚠
Danger
Never use the device with a defective power supply! Risk of
death from electrical shock!
Querx can alternatively be connected to a free USB-Port, if
no free outlet is available.
2.6 Network Configuration Via DHCP
Access the integrated web-interface via LAN, in order to
configure Querx.
The network can be configured automatically, using DHCP.
The status-LED will light up yellow if the device has received
valid data.
The LED will flash yellow if a network error occurs. In this
case, check that all wires are connected correctly.
Talk to your network administrator or connect the device to
your computer directly, if the problem persists.
First Use 13
2.7 Manual Network Configuration
An ethernet connection needs to be established, in order to
configure Querx. This initial connection is normally
configured automatically, which will let you access the device
as described in chapter 3.1 Accessing the Web Interface. The
network connection will need to be configured manually, if
your network does not support DHCP, or if the computer you
wish to use for the configuration does not support mDNS.

Basic Configuration 24
Lowest temperature values
TH models: Lowest humidity values
Average temperature values
TH models: Average humidity values
Querx can save up to 73,728 entries; the WLAN models have
a capacity of 4 million entries. This means that Querx can
store the data of 51 days, when logging one entry per
minute. Querx WLAN can track data for 7.5 years when using
the same settings. Data compression can be activated, in
order to increase the timespan that can be logged. If
compression is activated, entries are only saved if any
change has occurred since the last entry.
The memory is designed as a ring memory. If the memory’s
maximum capacity is reached, the oldest entries will be
overwritten.
1. Set the interval between logged entries by entering the
required number of minutes in the input field Logging
interval.
2. If required, activate data Compression.
3. Click Save to apply your changes.
