KNX TH65-AP

KNX Thermo-Hygrometer

The thermo-hygrometer 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 values 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.


  • KNX TH65-AP" KNX TH65-AP"
  • 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)
  • 7 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
