The Room Temperature Controller for the KNX building bus system 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 Room Temperature Controller has got an integrated PI controller for a heating and a cooling system (one or two step). The setpoint temperature is adjusted by means of the „+“ and „-“ touch buttons.
Thanks to KNX Secure, the room temperature controller communicates in encrypted form within the KNX network – for greater data security and protection against tampering.
The device has the standard dimensions of 55 mm and is complemented by a frame from the switch series used in the building. This allows it to blend seamlessly into the interior design.
