4. Wall Mount CO2 Monitor Operating Instructions Model ZGw08VRC Product Overview Thank you for selecting this CO2 wall mount monitor This product was developed to detect the presence of CO2 in the ambient air and help people to take care of the Indoor Air Quality The compact device is designed for use in HAVC in the building The demand controlled ventilation in the building also the greenhouse with the CO2 concentration control By using the CO2 monitor as the indicator it can easily get the current CO2 concentration together with the ventilation rate And then adjust the ventilation to the comfort condition automatically by the setting data So the over ventilation of the building can be reduced and the energy can be saved The CO2 monitor can be widely used in the office building green house school exhibition shopping mall The CO2 monitor is easy to use and has many features Dual Beam NDIR Non Dispersive Infrared technology used to measure CO2 concentration Three different LED display show the current Indoor Air Quality situation Linear analog output 0 10V Voltage 4 20mA Current and Relay output based on CO2 Level Reliable Sensor provides long term calibration stability The visual and audible alarm function can be adjustable by user Mounting bracket with terminal block provides quick easy installation Operation Instruction Back view Front view A Main LCD Display B Green LED Display H Enter Button
