Cala KNX T 101

Room Temperature Controller


  • Heating controller/thermostat
  • Glass surface with temperature display and +/- touch keys

The Room Temperature Controller Cala KNX T 101 measures the room temperature and displays the current value in white illuminated figures. Via the bus the device can receive an external measured value and process it with own data to overall temperature value (mixed value).

The Cala KNX T 101 has got an integrated PI controller for a heating and a cooling system (one or two step). The room temperature is adjusted by means of the „+" and „-" touch buttons.

The device is supplemented with a frame of the switch series used in the building, and thus fits seamlessly into the interior fittings.
