CDR-AL-LCD sensors and alarm units are designed to detect carbon dioxide concentration, temperature in the room spaces and provide alarm indication on high level of CO2 (white, amber and red display backlight). The CO2 sensor calibrate automatically its measurement. The CDR sensors have linear 0..10V signals outputs relating to CO2-concentration, temperature, and light level. The CDRC sensors have 4..20mA outputs. The sensors can be used for demand controlled ventilation in buildings.

CDR-AL-LCD transmitters can be installed on wall surface or on a wall mounting box in dry indoor environment. The CDR sensors come with a number of options such as passive setpoint, digital output, occupancy detection and passive resistive sensor elements.

The CDR -AL-LCD sensors can also operate as CO2, temperature, humidity(option) or light level (option) controllers modulating analogue outputs, or switching the digital output on based on the setpoints (the digital output are provided by fitting the additional -DO option). The configuration software SW-DCT-USB is used to configure it.
