Design and materials
A KNX thermostat for one room, or for two: it runs two thermostats or air conditioners. Turn the knob to change the temperature; press it and turn to choose the mode, the fan or the air conditioner's vanes. The two backlit buttons can run the room's lights or the thermostat. It measures the temperature, the humidity and the air quality, and a proximity sensor lights the buttons when someone comes near.

Brushed metal or silky matte
Four brushed finishes: aluminium in grey or black, brass and stainless steel. Six silky-matte finishes: aluminium painted in several layers and sealed, for a soft feel.
One knob
A solid metal knob does nearly everything: turn it for the temperature, press and turn it for the mode, the fan and the vanes.
A 3.5-inch display
The VA display sits behind black glass, above the bar with the knob and the two buttons.
Where it goes
On an inside wall of the room, at 1.4 m to the centre, away from the supply grille, direct sun and the kitchen. It fits a standard in-wall box (IEC/EN 60670).
