Cala KNX MultiTouch T CH

Push Buttons with Function Icons

 

  • KNX button
  • Printed glass surface
  • Integrated thermometer

 

The Cala KNX MultiTouch T CH push button has touch-sensitive buttons with which functions can be called up in the KNX building bus system. The glass surface is printed with areas for setting the light and temperature. LEDs are integrated in these areas and their behaviour can be adjusted. With Cala KNX MultiTouch T Light/Sunblind CH, an area for moving blinds/sunshades (up/down) is added, and with Cala KNX MultiTouch T Light/Scenes CH, an area for calling up scenes (3 scenes).

A temperature sensor is integrated into Cala KNX MultiTouch T CH. An external temperature reading can be received via the bus and processed with its own data to create a total temperature (mixed value).

The Cala KNX MultiTouch T CH has a PI controller for heating and cooling. The setpoint temperature can be changed using the "+" and "-" touch buttons.

Communication objects can be linked via AND and OR logic gates. The device is supplemented with a frame of the switch series used in the building, and thus fits seamlessly into the interio fittings.

  • Operating zone for light with 3 areas (switching and dimming)
  • Operating zone for temperature control with 3 areas (warmer, cooler, changeover heating/cooling)
  • A total of 9 areas, all of which can be assigned either to the intended bus functions or to other individual bus functions (switches, changeover switches, dimmers, blinds, awnings, shutters, windows, 8- or 16-bit encoders, scene call/saving)
  • LEDs can be set. All LEDs Off, all LEDs On, active LEDs Always On, all LEDs On for specific time after button pressed, active LEDs On for specific time after button pressed. Settable, as to whether LED flashes at block object value = 1. LED brightness can be pre-set for day and night
  • Area function when touching five or more push buttons. Can be configured as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
  • Scene control. 3 scene channels with 5 objects each
  • Temperature measurements. Mixed value from own measured value and external values (proportion can be set by percentage), output of minimum and maximum values
  • PI-controller for heating (one or two-level) and cooling (one or two-level) according to temperature. Regulation according to separate setpoints or basic setpoint temperature
  • 4 AND and 4 OR logic gates each with 4 inputs. All switching events as well as 8 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
