Nunio KNX MT
universal touch glass button
The Nunio KNX MT button is a universally applicable touch switch for the KNX building bus system. It has a monochrome touch display on which buttons can be displayed in different arrangements. The functions of the buttons are individually defined. This makes the button extremely flexible when requirements change (change of tenants in residential or commercial properties, hotel rooms, etc.).
A temperature sensor is integrated into the Nunio KNX MT button. The device can receive an external temperature measurement value via the bus and process it with its own data to produce a total temperature (mixed value).
Nunio KNX MT has a PI controller for heating and cooling. A temperature control display can optionally be shown on the display. The target temperature, mode and, if necessary, fan level can be set there.
Communication objects can be linked via AND and OR logic gates.
The switch-sized device has an integrated glass frame that is backlit by the display lighting. It is installed in a switch box.
