Datasheet

The room unit with CO2 sensor contains temperature sensor, NDIR CO2 sensor for carbon dioxide concentration measurement, optional humidity sensor, LCD with backlight. The binary output is controlled either on a remote basis, or as thermostat, hygrostat or CO2 controller. The units communicate over Modbus RTU / RS485 and they can be used as open system components with majority of building control system and controllers. Compared to the old series UI09x, these types dispose of knob and display blue backlight function and more accurate sensors.

Applications:
 
  • Air handling units and air condition in rooms with variable load – schools, cinemas, lecture halls etc.
 
  • Monitoring and recording of temperature, and CO2 concentration indoors
