Common features in all models:

• Colour touch display with display and operating pages for
  - 1× display of current measured values
  - 1× display of bus data (4 universal spaces)
  - 1× temperature control (incl. mode change, indication whether heating/ cooling active); can also be used as an extension unit for operating another controller
  - 3× drive operation (shading, window) with buttons, slider, position display (incl. slat position)
  - 3× switching or dimming of light (with percentage display)
  - 1× RGB light control
  - 1× light color temperature setting
  - 1× HCL control (adaption of light color temperature over adjustable periods of time)
  - 1× scenes (4 scenes with recall, storage, status indication)
  - weekly timer switch with 8 periods
  - 2× info page (each displays 2 text objects)
  - device settings
• Screen saver (clock, clock/indoor/outdoor temperature alternately, off) may be switched on or off
• Key tone may be switched on or off
• 4 inputs for binary contacts or T-NTC temperature sensor.
• 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) can be used as inputs for the logic gates. The output from 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
• 4 manipulated variable comparators to output minimum, maximum or average values. 5 inputs each for values received via communication objects
• 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

Cala Touch KNX AQS/TH functions (no. 70820, 70822):

• Measuring the CO2-concentration of the air, 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
• 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. Fan coil control
• PI controller for ventilation according to humidity and CO2-concentration: Ventilate/Air (one-level) or Ventilate (one or two-levels)

Cala Touch KNX TH functions (no. 70810, 70812):

• Temperature and air humidity measurement (relative, absolute), in each case 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
• 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 setpoints or basic set point temperature. Fan coil control
• PI controller for ventilation according to humidity: Ventilate/Air (onelevel) or Ventilate (one or two-level)

Cala Touch KNX T functions (no. 70800, 70802):

• Measuring the Temperature with a mixed value calculation. The share of internal measurement value and external value can be set as a percentage
• 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. Fan coil control
•
