after publication of these operating instructions.
2. Description
The Temperature Sensor KNX eTR gl measures the room temperature. The indoor
sensor can receive an external measured value via the bus and process it with own
data to an overall temperature value (mixed value).
The KNX eTR gl has a integrated PI controller for a heating/cooling system.
Functions:
•Measurement of temperature
•Mixed values from own measured value 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. Control according to separate target values or
basic target temperature

5 Description
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted.
2.2.1. Accuracy of the measurement
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated for in the device.
2.2.2. Device structure

with 2 screws is sufficient. For wall mounting,
use a fixing material suitable for the ground!

6 Installation
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted.
3. Installation
3.1. Installation location and preparation
The Temperature Sensor KNX eTR gl is made for wall mounting. The device can be
mounted directly on plaster or on device socket according to DIN 49073 and other
sockets, e.g. Swiss device socket.
May be installed and operated in dry interior rooms only.
When selecting an installation location, 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).
3.2. Mounting
DANGER!
Danger due to electrical voltage
(mains voltage)!
• The socket, in which the device is installed, must not contain cabling
with 230 V.
• Observe the regulations and standards applicable to SELV circuits
during installation and wiring of the KNX connection and inputs.
Prepare the device
Remove the front panel from the mounting. Release the lock by moving the front panel
a few millimetres upwards. The two parts can then be easily separated (Fig. 3).
7 Installation
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted.
Screw the mounting onto the wall or socket. The connecting wires (bus line +/-) are led
through the opening in the mounting.
Installation directly on the wall
The wires are pushed into the connection openings.
Installation on a socket
To avoid falsifying the temperature value, use a wind-proof socket and also seal the in-
let pipes against draughts.
Fig. 3 Locking of front panel and mounting
Remove the red-black KNX bus terminal, it is not
required.
Connect the bus +/- connecting wires to the spring-
loaded terminals on the front panel.
Fig. 4 Spring-loaded terminals
To pull it out, press the spring down, e.g. with a
screwdriver.
If there is a cavity behind the device, e.g. when
using a socket, you can use the red/black KNX bus
terminal for connection.
8 Notes on mounting and commissioning
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted.
Finish mounting
Snap the front panel into place on the mounting (see Fig. 3): Place it slightly above the
centre position, hook it in and slide it downwards.
The mounting must be installed so that the large opening faces downwards (see Fig.
4). This is necessary for a correct temperature measurement.
4. Notes on mounting and commissioning
Configuration is made using the KNX software as of ETS 5. The product file can be
downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the “Service” menu. There you will also find the
product manual.
After the bus voltage has been applied, the unit will enter an initialisation phase lasting
approx. 5 seconds. During this period, no information can be received or transmitted
via the bus.
4.1. Addressing of the device at the bus
The individual address is assigned via the ETS. A button and a control LED are located
on the unit for this purpose (Fig. 2, No. 6+7).
The programming button is located at the bottom outer side of the front panel of the
device and is recessed. Use a thin object to reach the button, e. g. a 1.5 mm² wire.
The equipment is delivered with the bus address 15.15.255. Another address can be
programmed using the ETS.
5. Maintenance and care
Fingerprints on the glass panel are best removed with a cloth moistened with water or
a microfiber cloth. Do not use an abrasive cleaning agent or aggressive cleansing
agents.
6. Disposal
After use, the device must be disposed of or recycled in accordance with the legal reg-
ulations. Do not dispose of it with the household waste!
