The SK30-TC-CO2-R is a KNX room sensor that measures temperature and CO2 and includes an integrated room temperature controller (RTR). It is a practical choice for demand-controlled ventilation in offices, meeting rooms and classrooms. A rotary knob lets occupants shift the setpoint locally by up to ±5 °C (±9 °F).
Available in White and Ultra Dark Grey (anthracite). The insert fits 55 mm (2.17 in) standard switch frames and includes a carrier frame for a 68 mm (2.68 in) in-wall box. Two floating binary inputs/outputs can also drive LEDs or a beeper, and no auxiliary supply is needed.
