KNX T-Objekt-UP

KNX Temperature Sensor

Follow up for N° 70178
The Temperature Sensor KNX T-Objekt-UP measures ambient temperature. 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-Objekt-UP provides three switching outputs with adjustable threshold values. The switching outputs and further communication objects can be linked via AND and OR logic gates. Additionally, an integrated actuating variable comparator can compare and output values that are received via communication objects. The sensor has got a PI controller for heating and cooling.
The device is completed with a frame and cover of the switching series installed in the building and thus merges with the interior.


  • KNX T-Objekt-UP KNX T-Objekt-UP
  • 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) depending on temperature. Control according to separate target values or basic target temperature 
  • 3 switching outputs with adjustable threshold values (Threshold values can be set by parameter or via communication objects)
  • 8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as well as 16 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
  • 2 actuating variable comparators for output of minimum, maximum or avarage values. Each with 5 inputs (for values received via communication objects)
  • Configuration is made using the KNX software ETS
