The Rosa Metal KNX Touch Thermostat merges a capacitive thermostat display with programmable touch buttons in a frameless 85 mm wide brushed-aluminium plate. Available with 4, 6, or 8 auxiliary keys (INT-RMT2 / RMT3 / RMT4), it controls HVAC setpoints and room functions — lighting, blinds, DND/MUR, and scenes — from one premium wall device.

The integrated sensor achieves ± 0.3 °C accuracy with automatic heating/cooling transition, fan speed control, and modes for Comfort, Night, Away, and Protection. HVAC outputs support fan coil, split AC, VRF/VRV, PI relative, and PI on/off (PWM).
