The Schneider Electric UNICA X thermostat combines an ultra-slim metal room station with 5 or 8 operating keys, integrated temperature sensor, proximity wake, and full HVAC control. One 86 mm plate manages lighting, blinds, scenes, and climate — supporting FCU, VRF, floor heating, and ventilation with a backlit display for setpoint and mode feedback.
