KNX T-UN

Universal KNX Temperature Sensors

The Temperature Sensor KNX T-UN consists of evaluation electronics and measuring sensor. The sensor 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-UN 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.

Models:

No. 70220 KNX T-UN 130, Sensor up to 130°C, IP 68
No. 70221 KNX T-UN 100, Sensor up to 100°C, IP 43

  • KNX T-UN 100 with evaluation unit (70221) KNX T-UN 100 with evaluation unit (70221)
  • 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 via ETS
