Product Description
The Temperature Sensor KNX T-AP measures temperature in indoor and outdoor areas.
The sensor can receive an external measured value via the bus and process it with the
own data to an overall temperature (mixed value).
The KNX T-AP provides four switching outputs with adjustable threshold values as well
as additional AND and OR logic gates. The sensor has got a PI controller for heating and
cooling.
Functions:
•Measurement of temperature
•Mixed value from own measured value and external value (proportions can be set
in percentage)
•PI controller for heating (one or two step) and cooling (one or two step)
•4 switching outputs with adjustable threshold values (Threshold values can be
set by parameter or via communication objects)
•4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as well
as 8 logic inputs (in the form of communication objects) may be used as inputs for
the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x
8 bits
Configuration is made using the KNX software ETS. The programme file (format VD2)
and the manual can be downloaded from the Elsner Elektronik homepage on
www.elsner-elektronik.de in the “Service” menu.

•EN 61000-6-1:2004
The product has been tested for the above mentioned standards by an accredited EMV
laboratory.
Installation and Commissioning
Installation, inspection, commissioning and troubleshooting
of the sensor must only be carried out by a competent electrician.
Disconnect all lines to be assembled, and take safety precautions against accidental
switch-on.
The sensor is exclusively intended for appropriate use. With each inappropriate change
or non-observance of the instructions for use, any warranty or guarantee claim will be
void.
After unpacking the device, check immediately for any mechanical damages. In case of
transport damage, this must immediately notified to the supplier.
If damaged, the sensor must not be put into
operation.
If an operation without risk may supposedly not be guaranteed, the device must be put
out of operation and be secured against accidental operation.
The sensor must only be operated as stationary system, i.e. only in a fitted state and after
completion of all installation and start-up works, and only in the environment intended
for this purpose.

Elsner Elektronik does not assume any liability for changes in standards after publication
of this instruction manual.
Installation position
The sensor is designed for surface mounting. 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
•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).
For outdoor installation it must be ensured that a 60 cm gap is left below the sensor in
order to prevent it from being snowed during snowfall.
The sensor must be mounted vertically. The measurement probe and the cable outlet
must point downwards.

Connection of the temperature sensor
Remove the screwed on cover. Lead the KNX bus connection cable through the cable
entry on the bottom of the casing and connect the bus +/- to the terminal provided for
this purpose. Screw the cover back on.
Notes on installation
Do not open the temperature sensor if penetration of water (rain) is likely: Only a couple
of drops could damage the electronic.
Maintenance
The temperature sensor should regularly be checked for dirt and cleaned, if required.
Due to safety reasons, the sensor should always be
disconnected from the bus current when performing
maintenance and cleaning works (e.g. by deactivating/
removing fuse).
