Duct CO2 controllers
HVAC controllers to regulate CO2, temperature and relative humidity in air ducts. They can directly regulate EC fan speed or control AC fan speed controllers and damper actuators. The black mounting flange simplifies installation on circular ducts. Settings can be adjusted via Modbus RTU communication. The controller's algorithm regulates a single analogue output based on the measured CO2, temperature and relative humidity values. These controllers use the NDIR technology to detect the CO2 concentration in the air duct.
