Telaire 8012 series CO2 switch

Telaire 8012 series CO2 switch

The Telaire 8012 series CO2 switch is a low-cost wall mounted sensing solution for ventilation control. The 8012 provides an intuitive VLI (Visual Level Indicator) display for CO2 thresholds, to maintain air quality in enclosed spaces (school classrooms, offices, gymnasiums, theatres, etc.).

 

Not Available In North America

 

The simple LED array indicates increased CO2 concentrations based on predetermined thresholds. The LED smoothly transitions between blue, green, yellow and red as the CO2 concentration increases.

 

Unlike scientific displays, training to understand PPM values is not prerequisite with this innovative product. Indication shows under ventilation (red) or over ventilation (blue), which translates to low air quality (red) or too much energy being used to heat or cool unnecessary outside air (blue). In a heating only application the blue should be ignored if windows are opened to provide cooling.
