Cala KNX M-T

Push Buttons

The Cala KNX M-T push button has touch-sensitive buttons, with which functions in the KNX building bus system can be called, such as switch lights and devices, dim, activate drives, send values, scenarios. An LED is integrated into each touch button, the behaviour of which can be adjusted.

A temperature sensor is integrated into Cala KNX M-T. An external temperature reading can be received via the bus and processed with its own data to create a total temperature (mixed value). Communication objects can be connected by 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 interior fittings.

Cala KNX M1-T functions:

  • 1 Touch bus button, can be configured as switch, selector switch, dimmer, blind (position and slats up/stop OR down/stop), shutters (up/down/stop), awning (in/out/stop), window (closed/open/stop), as 8 or 16-bit encoder or for scenario recall/storage

Cala KNX M2-T functions:

  • 2 Touch bus button, can be configured as switch, selector switch, dimmer, for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
  • Area function when touching both push buttons. Can be configured as switch, selector switch, as 8 or 16 bit encoder or for scenario recall

Cala KNX M4-T functions:

  • 4 Touch bus button, can be configured as switch, selector switch, dimmer, for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
  • Area function when touching three or more push buttons. Can be configured as switch, selector switch, as 8 or 16 bit encoder or for scenario recall

Function of all models:

  • One LED per touch area. On for object value = 1 / Off for object value = 0, On after pressing button for settable time or always off. Settable, as to whether LED flashes at block object value = 1
  • Temperature measurements. Mixed value from own measured value and external values (proportion can be set by percentage)
  • 2 AND and 2 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

Configuration is made using the KNX software ETS 5
