5 Description
Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
1. Description
The Sensor Intra-Sewi KNX TH-Pr for the KNX building bus system detects motion.
It measures the temperature and the air humidity and calculates the dew-point. Via the
bus, the indoor sensor can receive external values of temperature and humidity and
process them further with its own data to a total value (mixed value, e.g. room aver-
age).
All measurement values can be used for the control of limit-dependent switching out-
puts. States can be linked via AND logic gates and OR logic gates. In addition, an inte-
grated actuating variable comparator can compare and output variables that were re-
ceived via communication objects.
Integrated PI-controllers control ventilation (humidification/dehumidification accord-
ing to humidity) and heating/cooling (according to temperature). The Intra-Sewi KNX
TH-Pr can output a warning to the bus as soon as the comfort field, as per DIN 1946,
is left.
Functions:
•Motion detection
• Measuring the temperature and air humidity (relative, absolute), each with
mixed value calculation. The share of internal measurement value and
external value can be set as a percentage
• Bus message, whether the values for temperature and air humidity are within
the comfort field (DIN 1946). Dew point calculation
•Threshold values can be adjusted per parameter or via communication
objects
•PI-controller for heating (one or two-stage) and cooling (one or two-stage)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature
•PI controller for humidity according to humidity: Ventilate/Air (one-stage) or
Ventilate (one or two-stage)
•4 AND and 4 OR logic gates, each with 4 inputs. All switching events as well
as 16 logic inputs (in the form of communications 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
•2 actuation variable comparators to output minimum, maximum or
average values. 5 inputs each for values received via communication objects
Configuration is made using the KNX software ETS. The product file can be down-
loaded from the Elsner Elektronik website on www.elsner-elektronik.de in the “Ser-
vice” menu.

7 Installation and start-up
Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
1.1.1. *Measuring accuracy
Deviations in measured values due to interfering sources (see chapter installation lo-
cation) must be corrected in the ETS in order to achieve the specified accuracy of the
sensor (offset).
During the Temperature measurement, the self-heating of the device is taken into
consideration by the electronics. It is compensated by the software, therefore the dis-
played/output indoor temperature measuring value is correct.
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 assem-
bled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Installation location
Install and use only in dry interior rooms! Avoid condensation.

8 Installation and start-up
Sensor Intra-Sewi KNX TH-Pr • Version: 11.06.2018 • Technical changes and errors excepted.
The Sensor Intra-Sewi KNX TH-Pr is installed in a false ceiling or a standard con-
nection socket (Ø 60 mm, 42 mm deep).
The device must be installed on the ceiling, so that the movement capturing takes
place from above. Make sure that the desired area is covered by the sensor's coverage
angle and that no obstacles obstruct the recording.
When selecting an installation location, please ensure that the measurement results of
temperature and humidity are affected as little as possible by external influences.
Possible sources of interference include:
• Direct sunlight
• Drafts from windows and doors
• Draughts from ducts coming from other rooms or the outdoors
• 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 empty ducts which lead from warmer or colder areas to
the sensor
Measurement variations from such sources of interference must be corrected in the
ETS in order to ensure the specified accuracy of the sensor (offset).
