Real-time detecting CO2 level, temperature and humidity with the local programmable control. 2.Wall mounting, LCD display3.Carbon dioxide sensor, temperature sensor and humidity sensor are internal. The three values can be apart set.4.Non-Dispersive Infrared Detector (NDIR) CO2 sensor, 15 years lifetime, CO2 setting range is selectable: 0 2000ppm / 0 20000ppm /0 50000ppm5.Special ABC Logic with patented Self Calibration Algorithm makes the CO2 sensor used up to 15 years6.Temperature setting range: 5 45;Humidity setting range: 595%RH7.rovid three relays outputs to control a CO2 generator, a temperature device and a humidity devise or a ventilator. 8.Special photosensitive sensor detection can make the working mode of the CO2 generator changeover automatically in day and night.9.Provide brightness adjustment range to make day/night limit setting by end users.10.RS-485 communication interface with 15KV antistatic protection makes the controller being connected with PC (option)11.Multiple functions, high performance, low price, make it praiseworthily.
