AQR2535NNWQ KNX Room Sensor Front Module with Temperature, Humidity and CO2 LED Indicator S55720-S219
The AQR2535NNWQ is an enhanced front module combining active temperature and relative humidity sensing with a built-in CO2 LED indicator for plug-in mounting onto AQR2570.. series KNX base modules. Beyond the dual-parameter sensing of AQR2535NNW, this variant adds a visual CO2 alert via LED display, providing occupants with immediate air quality feedback without requiring a separate CO2 controller device.
The LED CO2 indicator supports demand-controlled ventilation by alerting occupants and building managers to elevated CO2 concentrations. When combined with the base module's KNX S-Mode communication, ventilation sequences can be centrally triggered via group objects. The housing is 55 × 55 × 38 mm — slightly deeper than standard front modules — to accommodate the LED electronics, while retaining the titanium white DELTA frame aesthetic.
