![CDATA[The CO2, temperature, air pressure and humidity sensor comprehensively records the air quality. The CO2 sensor measures from 390 to 5,000 ppm and provides air pressure compensated values. The temperature sensor has a measuring range of 0 to +50 °C, while the humidity sensor records values from 0 to 100%. With a humidity comparator function and a clearly structured ETS, the device is easy to handle and install. The modern, flat design is suitable for surface mounting. With the GS 41.00 knx and GS 41.01 knx models, the setpoint temperature can be manually adjusted by ±3 ° (step size 0.5 °) via a touch control panel. Additional functions include a party function, extended setpoint control and temperature control with up to four sensor values as well as a VAV controller. The device is operated via KNX bus voltage and has a permissible ambient temperature of 0 to +50 °C, with a housing made of self-extinguishing thermoplastic (protection class IP 20).]]>
