GENERAL The AQS51-KAM and AQS 61-KAM sensors/controllers for duct mounting measure the carbon dioxide (CO2) concentration and the temperature in the return or outside air. They are used in ventilation and air conditioning systems to control the amount of fresh outside air being supplied to the occupants for acceptable indoor air quality and to reduce unnecessary conditioning of outside air during lowoccupancy periods.
