KNX T-B-UP, white

KNX Temperature Sensor with Display and Buttons


The Temperature sensor KNX T-B-UP measures the room temperature. Via the bus, the sensor receives an external measuring value and processes it to an overall temperature (composite result) together with its own data. The KNX T-B-UP features two buttons that may be used to modify the room temperature (nominal temperature), to switch between the operating modes or as freely programmable bus buttons.
The KNX T-B-UP provides three switched outputs whose threshold values can be adjusted. Switched outputs and other communication objects may be linked via AND and OR logic gates. In addition, an integrated control variable comparator compares and outputs variables that were received via communication objects. The sensor features a PI control for heating and cooling.
The integrated display shows own value as well as data received via the bus (e.g. date, time of day). The housing is supplemented with a frame of the switch series used in buildings, and thus fits seamlessly into the interior fittings

Delivery without frame

  • KNX T-B-UP with frame (not included in the delivery) KNX T-B-UP with frame (not included in the delivery)
  • Temperature measurements
  • Composite value from own measured value and external value (proportions are adjusted as a percentage)
  • Display 1-3 lines (measured value or values received via bus) or display for temperature control
  • 2 buttons. Configuration as a bus button or to modify the nominal temperature and to switch between the operation modes
  • 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
  • 3 switched outputs with variable threshold values (thresholds are set optionally by parameters or via communication objects)
  • 8 AND and 8 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) are used as inputs for the logic gates. The output from each gate can be configured optionally as 1-bit or 2 x 8-bit
  • 2 control 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
