Mini-Sewi KNX TH-Pr

Presence Detector with Temperature/Humidity Sensor

The Sensor Mini-Sewi KNX TH-Pr detects motion. It measures the temperature and the air humidity and calculates the dew-point. Via the bus, the indoor sensor can receive external values of temperature and humidity and process them further with its own data to a total value (mixed value, e.g. room average).

All measurement values can be used for the control of limit-dependent switching outputs. States can be linked via AND logic gates and OR logic gates. In addition, an integrated actuating variable comparator can compare and output variables that were received via communication objects.

Integrated PI-controllers control ventilation (humidification/dehumidification according to humidity) and heating/cooling (according to temperature). The Mini-Sewi KNX TH-Pr can output a warning to the bus as soon as the comfort field, as per DIN 1946, is left.

  • Motion detection
  • Measuring the temperature and air humidity (relative, absolute), each with mixed value calculation. The share of internal measurement value and external value can be set as a percentage
  • Bus message, whether the values for temperature and air humidity are within the comfort field (DIN 1946). Dew point calculation
  • Switching outputs for all measured and computed values. Threshold values can be adjusted per parameter or via communication objects
  • PI-controller for heating (one or two-stage) and cooling (one or twostage) according to temperature. Regulation according to separate setpoints or basic setpoint temperature
  • PI controller for humidity according to humidity: Ventilate/Air (one-stage) or Ventilate (one or two-stage)
  • 4 AND and 4 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
  • 8 multi-function modules (computers) for changing the input data by calculations, by querying a condition or by converting the data point type
  • 2 actuation 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
