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

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!

12 Setting the parameters
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted
The unit can calculate a mixed value from its own reading and an external value. Set
the mixed value calculation if desired. If an external portion is used, all of the following
settings (threshold values, etc.) are related to the overall reading.
The minimum and maximum readings can be saved and sent to the bus. Use the
"Reset temperature min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.
8.4. Temperature PI controller
Activate the controller if you want to use it.
General rules
Decide in which cases nominal values and delay times received per object are to be
kept. The parameter is only taken into consideration if the setting by object is activated
further down. Please note that the setting "After power restoration and programming"
should not be used for the initial start-up, as the factory settings are always used until
the first call (setting via objects is ignored).
For an adequate regulation of the indoor temperature, comfort, standby, eco and build-
ing protection modes may be used.
Comfort when present,
Standby when absent,
Eco as a night-time mode and
Frost / heat protection (building protection) e.g. when the window is open.
The settings for the temperature control include the setpoint temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).
The mode may be switched with two 8 bit objects of different priority. Objects
„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
Use external measured value No • Yes

13 Setting the parameters
Temperature Sensor KNX eTR gl • Version: 07.04.2021 • Technical changes and errors excepted
1 = Comfort
2 = Standby
3 = Eco
4 = Building protection
Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others are used to activate comfort mode or frost/heat pro-
tection mode. The comfort object then blocks the eco/standby object, and frost/heat
protection objects have the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"
Select the mode to be activated after reset (e.g. power failure, reset of the line via
the bus). (Default).
Then configure a temperature control block using the blocking object.
Specify when the current control variables are to be sent to the bus. Periodic trans-
mission is safer if a message does not reach a recipient. You may also set up periodical
monitoring by the actuator with this setting.
The status object reports the current status of the output (0 = OFF, 0 = ON) and may
for example be used for visualisation, or to switch off the heating pump as soon as the
heating is switched off.

Then define the type of setting. Heating and/or cooling may be controlled in two
stages.
General setpoint values
You may enter separate setpoint values for each mode or use the comfort setpoint as
a basic value.
If you are using the controls for both heating and cooling, you may also select the set-
ting "separately with switching object". Systems used for cooling in the summer and
for heating in the winter can thus be switched from one to the other.
If you are using the basic value, only the deviation from the comfort setpoint value is
listed for the other modes (e. g., 2°C less for standby mode).
The grades for the setpoint changes is predefined. Whether the change remains active
only temporarily (do not store) or remains stored even after restoration of power (and
programming) is determined in the first section of "General controller". This also ap-
plies to a comfort extension.
The controller can be switched from eco mode, i.e. night mode, to comfort mode via
the comfort extension. This means that the comfort setpoint can be maintained for
longer, for example when having guests. The duration of this comfort extension period

mode.
Setpoint Comfort
Comfort mode is usually used for daytime mode when people are present. A starting
value is defined for the comfort setpoint as well as a temperature range in which the
nominal value may be modified.
If setpoint values are entered separately:
If the comfort setpoint value is used as a basis:
If the comfort setpoint is used as the basis, the increase/decrease of this value is indi-
cated.
If the comfort setpoint is used as the basis, a dead zone is determined for the control
mode "heating and cooling" to avoid direct switching from heating to cooling.
Setpoint for standby
Standby mode is usually used for daytime mode when people are absent.
If setpoint values are entered separately:
A starting setpoint value is defined as well as a temperature range in which the setpoint
value may be changed.

Setpoint values for frost/heat protection (building protection)
The building protection mode is used, for example, as long as windows are open for
ventilation. Setpoints for frost protection (heating) and heat protection (cooling) are
determined which may not be modified from outside (no access via operating devices
etc.). The building protection mode may be activated with delay, which allows you to
leave the building before the controls switch to frost/heat protection mode.

General variables
This setting appears for the control types "Heating and Cooling" only. This is where you
can decide whether to use a common variable for heating and cooling. If the 2nd stage
has a common variable, this is also where you determine the control mode of the 2nd
stage.
When using the variable for a 4/6 way valve:
0%...100% Heating = 66%...100% variable
OFF = 50% variable
0%...100% Cooling = 33%...0% variable
8.4.1. Heating control stage 1/2
If a heating control mode is configured, one or two setting sections for the heating
stages are displayed.
In the first stage, heating is controlled by a PI controller which allows to either enter
control parameters or select predetermined applications.
In the second stage (therefore only in case of 2-stage heating), heating is controlled via
a PI or a 2-point-control.
In stage 2, the setpoint deviation between the two stages must also be specified, i.e.
beyond which setpoint undershoot the second stage is then added.
PI controller with control parameters:
This setting allows individual input of the parameters for PI control.

Specify the deviation from the setpoint value at which the maximum control variable
value is reached, i.e. the point at which maximum heating power is activated.
The reset time shows how quickly the controller responds to deviations from the set-
point. In case of a short reset time, the control responds with a fast increase of the con-
trol variable. In case of a long reset time, the control responds somewhat less urgently
and needs longer until the necessary control variable for the setpoint deviation is
reached.
You should set the time appropriate to the heating system at this point (observe man-
ufacturer's instructions).
Now specify what should be sent when the control is blocked. Set a value greater 0
(=OFF) to receive a basic heating stage, e.g. for floor heating.
On release, the control variable follows the rule again.
In case of a common control variable for heating and cooling, 0 is always transmitted
as a fixed value.
PI control with predetermined application:
This setting provides fixed parameters for frequent applications.
