5 Description
Temperature evaluation unit KNX T6-UN-B4 • Version: 17.12.2019 • Technical Changes and Errors excepted.
1. Description
The Temperature evaluation unit KNX T6-UN-B4 has six inputs for T-100 or T-130
temperature sensors and four analogue/digital inputs, which can for example be used
for buttons or T-NTC temperature sensors. The temperature measurement values for
all inputs can be processed with external measurement values to provide a combined
value (total temperature, average temperature).
All measured values can be used for the control of threshold value-dependent
switching outputs. Six PI controllers control the heating and cooling (one- or two-
stage). Logic gates can be used to set up additional operations.
Functions:
•6 temperature inputs for T-100 or T-130 sensors
•4 analogue/binary inputs, for example for buttons or T-NTC temperature
sensors
•Combined value calculation for all connected temperature sensors
(proportion of internal measurement value and external value can be set as a
percentage)
•Threshold values can be adjusted per parameter or via communication
objects
•6 PI controllers for heating and cooling (one- or two-stage).
•4 AND and 4 OR logic gates with 4 for each input. 16 logic inputs (in the form
of communication objects) can be used as inputs for the logic gates. The output
of each gate can be configured optionally as 1-bit or 2 x 8-bit
Configuration is made using the KNX software ETS. The product file can be
downloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
“Service” menu.

6 Installation and start-up
Temperature evaluation unit KNX T6-UN-B4 • Version: 17.12.2019 • Technical Changes and Errors excepted.
The product conforms with the provisions of EU directives.
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.

7 Installation and start-up
Temperature evaluation unit KNX T6-UN-B4 • Version: 17.12.2019 • Technical Changes and Errors excepted.
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 evaluation electronics of the sensor is installed in a socket. When selecting an
installation location for the measuring sensor, 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
• 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 which lead from warmer or colder areas to the sensor
Temperature variations from such sources of interference must be corrected in the ETS
in order to ensure the specified accuracy of the sensor (temperature offset).
2.3. Connection
The cables of the T-100, T-130 and T-NTC temperature sensors can be extended to a
maximum of 10 m.

8 Addressing of the device at the bus
Temperature evaluation unit KNX T6-UN-B4 • Version: 17.12.2019 • Technical Changes and Errors excepted.
2.4. 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.
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another
address into the ETS by overwriting the 15.15.255 address or by teaching via the
programming button.
