Room sensor in the NOVOS design for measuring CO2 , mixed gas (VOC), optionally temperature and humidity (relative, absolute, enthalpy, dew point) and traffic light indication with a 7-color LED. The maintenance-free sensor forms the basis for a pleasant room climate and well-being. Especially designed for use in schools, office buildings, hotels, cinemas and similar applications. Threshold values can be individually configured via Thermokon NOVOSapp. For models with set point and occupancy button, please refer to the 'NOVOS 3 x' in the chapter 'Room Operating Units'.

Measured valuesCO2, VOC, temperature + humidity (depending on the device), each output can be set to get a variable mix of CO2 and VOC by configuration

Mountingflush-mounted on standard EU box (Ø=60 mm), or to be mounted flat onto the surface using screws, base part can be mounted and wired separately
Notesfor configuration an optional programming dongle (Bluetooth) is available (refer to accessories), mixed gas sensors detect gases and vapours which can be oxidised (burnt): Body odours, tobacco smoke, exhalations emitted by materials (furniture, carpets, paint, glue ...)
