Air Quality Multisensor

KNX CO2, humidity, temperature sensor and atmospheric pressure with user interface to change the temperature setpoint. The device is a combined sensor for CO2, temperature and humidity measurement (relative humidity) and atmospheric pressure. In addition, the sensor has 5 inputs: 2 binary inputs, 1 input can be confiured as a binary or analog input, 2 inputs can be configured as binary or as temperature sensor input (PT1000, 10kΩ PTC, 2-/10-/12-/15-/33-/47 kΩ NTC). It is used to monitor the air quality in meeting rooms, offices, schools/kindergartens, passive or low-energy houses and living areas without controlled ventilation. The CO2 content of the air is a verifiable indicator of the ambient air quality. The higher the CO2 content, the worse the ambient air is. The sensor provides the following data and controls for KNX: CO2, relative humidity, temperature, dew point, air pressure, VAV control, temperature controller. Together with the right actuators offers a perfect ventilation and temperature control. The CO2 content of the air is a verifiable indicator of the ambient air quality. The higher the CO2 content, the worse the ambient air is. KNX software functions: CO2 control/sensor, Relative humidity sensor/control/comparator, Temperature sensor/alarms/control, dew point temperature/alarm, air pressure sensor, VAV control for 2 blocks,. 4 digital inputs to switch, dim, blind, value, scene, switching sequences, multiple operation and pulse counter. There are 2 independent measured value thresholds for CO2, air pressure and temperature, one threshold for relative humidity. Actions are carried out if the thresholds are not reached or if they are exceeded. Different parameters can be selected for the two different blocks for VAV control. The devices allows the CO2 calibration by bus. Power supply: bus voltage. Current consumption from bus: max. 10 mA. Ambient temperature: -5 °C-+50 °C. Measuring range, CO2: 390 - 5000 ppm,measuring range humidity: 0 % - 100%, measuring range atmospheric pressure: 300 hPa - 1100 hPa, measuring range temperature: 0°C - +50°C. Type of protection: IP 20 in accordance with DIN EN 60529. Dimensions: 80,5x80,5x17 mm. Colour: polar white.
