Room CO2 controllers
Indoor HVAC sensor controllers to regulate CO2, temperature, relative humidity and measure the ambient light level. They are designed for indoor use and have a smooth, contemporary look that will blend in with most interiors. CO2 measurement is based on the photoacoustic sensing technology. The measurement of the ambient light can be used to control the ventilation system based on the occupancy of the room. These controllers can directly regulate EC fan speed or control AC fan speed controllers and damper actuators. 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.
