YOUR PARTNER IN SENSOR TECHNOLOGY HVAC Room CO2 Switch EE80 room CO2 switch is based on the non-dispersive infrared (NDIR) measurement principle. A patented auto-calibration procedure compensates for the aging of the infrared source and ensures outstanding long term stability. The switch threshold and hysteresis can be set with potentiometers on the electronics board. The measured CO2 data can be indicated on the optional LC display. Two different enclosure designs ensure professional appearance according to regional standards. building management for residential and office areas modern design ventilation control optional display easiest installation long-term stable Technical Data_ Measurement principle Working range_ Temperature dependence Long term stability_ Sample rate Switch Output Contact material General Supply voltage_ Current consumption Housing material Protection class Electrical connection_ Electromagnetic compatibility Working temperature range Storage temperature range Non-Dispersive Infrared Technology (NDIR) E+E Dual Source Infrared System_ 0...5000 ppm:_< ± (50 ppm +3 % of measuring value) Ag+Au clad_ US Version: UL94V-0 approved / EU Version: UL94HB approved 1) warm up time for performance according specification
