AERASGARD® RFTM-PS-Modbus（ LCD）Multifunctional indoor climate sensor AERASGARD® RFTM - LQ - PS - CO2 - Modbus (maximum expansion level) with Modbus connection, in an elegant plastic housing with snap-on lid, base with 4-hole attachment, optionally with / without display, type variant RFTM - CO2 - Modbus optionally with / without setpoint potentiometer. The room sensor is used for detecting the air humidity (0…100 % RH), room temperature (0...+50 °C), air quality (VOC) (0…100 %), the fine dust (PM) (0...1000 μg/m3) and CO2 content (0...5000 ppm) as well as a room control unit (% setpoint). International system of units SI (default) can be changed to imperial (via Modbus). The following parameters can be accessed via the Modbus: Temperature, relative humidity, air quality (VOC), fine dust (PM) and carbon dioxide (CO2). Use just one device to monitor and control the entire indoor climate effectively. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being. It is used in offices, hotels, convention centres, apartments, shops, etc. One sensor for every 30 m2 of room area is recommended.
