Promotional item Cala KNX AQS/TH (00394)

The Sensor with Cala KNX display for the KNX bus system measures various ambient climate. Via the bus, the indoor sensor can receive external values and process them further with its own data to a total value (mixed value, e.g. room average).

All measured values can be used for the control of threshold value-dependent switching outputs. States can be linked via AND logic gates and OR logic gates. Multi-functional modules change input data as required by means of calculations, querying a condition, or converting the data point type. In addition, an integrated manipulated variable comparator can compare and output variables that were received via communication objects.
Integrated PI-controllers control ventilation (according to humidity or CO2-concentration) and/or heating/cooling (according to temperature), depending on the respective model.

Cala KNX features a touch display that shows various display and control pages depending on the individual configuration. There is one page available that shows the current measured values, a menu area to adjust device settings and pages with touch control elements for internal temperature control, for light (manual switching or dimming), for shades or windows (manual operation).
Cala KNX is supplemented with a frame of the switch series used in buildings, and thus fits seamlessly into the interior fittings.

  • Bus message, whether the values for temperature and air humidity are within the comfort field (DIN 1946). Dew point calculation
  • Threshold values can be adjusted per parameter or via communication objects
  • PI-controller for heating (one or two-level) and cooling (one or two-level) according to temperature. Regulation according to separate set points or basic set point temperature
  • PI controller for ventilation according to humidity and CO2-concentration: Ventilate/Air (one-level) or Ventilate (one or two-levels)
  • Summer compensation for cooling systems. A characteristic curve matches the target temperature in the room to the external temperature and sets the minimum and maximum target temperature values
  • Configuration is made via the KNX software ETS
