The intelligent temperature and humidity controller adopts an analog voltage output temperature and humidity sensor, and displays the temperature and humidity values in the form of digital tubes. The product can also be equipped with RS485 communication interface or alarm switch output, which is used to realize the remote transmission of ambient temperature, humidity value and working state parameters to the upper computer, which is suitable for the requirements of unattended substations. Users can set the upper and lower limits of temperature and humidity, cycle display mode, communication parameters, etc. at will through key programming. The product has strong anti-interference ability and high reliability, and meets the GB/T15309-1994 standard.
