The EAE Oria KNX Thermostat Switch combines a digital LCD room thermostat with programmable KNX push-buttons in one flush-mounted plate. Available as 2-fold (4 keys), 3-fold (6 keys), or 4-fold (8 keys), it delivers climate control and room automation from a single 60 × 60 mm junction box — ideal for hotel guest rooms and residential zones.

The integrated temperature sensor achieves ± 0.3 °C accuracy with automatic heating/cooling transition. HVAC outputs support PI relative, PI on/off (PWM), on/off, fan coil, split unit, and VRF/VRV systems. Programmable buttons handle switching, dimming, blinds, scenes, and status LEDs alongside the thermostat display.
