Room Sensors Climate+Air Quality


Active room sensor in the NOVOS 5 enclosure for measurement of temperature, humidity (relative and absolute humidity, enthalpy, dew point), CO2 and mixed gas (VOC) depending on the variant. The maintenance-free sensor contributes to a pleasant room climate and well-being. Typical applications include schools, office buildings, hotels or cinemas. The NOVOS 5 uses an LCD with color-changing backlight for displaying the measured values and exceeding threshold values. Different parameters like the display settings can be individually configured via Thermokon NOVOSapp. Optionally, operating elements for controlling HVAC systems can be added (see product NOVOS 5 x in the chapter 'Room Operating Units').
