Description
The Temperature and Humidity Sensor KNX TH65-AP measures temperature and
humidity in indoor and outdoor areas and calculates the dew point. The sensor can
receive external measured values via the bus and process them with the own data
to an overall temperature and overall air humidity (mixed values).
The KNX TH65-AP provides seven switching outputs with adjustable threshold va-
lues as well as additional AND and OR logic gates. The sensor has got a PI controller
for heating and cooling (depending on temperature) and for ventilation (depending
on air humidity) and it can emit a warning to the bus as soon as the area of optimum
comfort (according to DIN 1946) is left.
Functions:
•
Measurement of temperature and air humidity (relative and absolute),
calculation of dew point
•
Mixed values from own measured values 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
•
PI controller for ventilation depending on humidity: Dehumidify/humidify
(one step) or dehumidify (one or two step)
•
Threshold values can be adjusted per 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 product file can be dow-
nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the
"Service" menu.

2.
Use the device exclusively for building automation and observe the operating inst-
ructions. Improper use, modifications to the device or failure to observe the opera-
ting instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
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.
2.1. Location
The sensor is designed for surface mounting. When selecting an installation loca-
tion, please ensure that the measurement results are affected as little as possible by
external influences. Possible sources of interference include:
•
•
•
•
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 out-
let must point downwards.
2.2. Notes on mounting and commissioning
Do not open the temperature sensor if penetration of water (rain) is likely: Only a
couple of drops could damage the electronic.
Do not dip the measuring tip (metal sleeve with sensor) in water.
Avoid the bedewing of the device. For critical applications, where condensate for-
mation is expectable, please ask Elsner Elektronik for customized solutions.

2.3.2. Connection of the sensor
Remove the screwed on cover. Lead the KNX bus connection cable through the ca-
ble entry on the bottom of the casing and connect the bus +/- to the terminal provi-
ded for this purpose. Screw the cover back on.
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.
The device is supplied with the bus address 15.15.255. You can program another ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming button.
Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• Inspect the device for damage before installation. Only put undamaged
devices into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against
unintentional switch-on if risk-free operation is no longer guaranteed.
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
