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.

CO2 Switch for harsh environment
Robust housing with integrated dust and dirt filter to protect against environmental influences. A CO2 switch for demanding climate control.
Duct mount CO2 Switch
Measurement of the CO2 concentration in ventilation ducts. The ideal CO2 switch for building automation and demand controlled ventilation.
Controlled ventilation of living areas
Controlled ventilation of living areas is a prerequisite for efficient reduction of energy consumption in low-energy and passive houses. In addition to reduced energy costs due to reclamation of heat, controlled ventilation of living areas also ensures good air in the building

What is the difference between a 2 wire and a 3 wire current output?
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
