1、 Product Overview

The intelligent temperature and humidity controller adopts a digital temperature and humidity sensor, which displays temperature and temperature values in the form of a digital tube. It is equipped with fan and heater contacts, and has functions such as heater disconnection alarm and sensor fault indication. The product can also be equipped with RS485 communication interface or alarm switch output, which is used to remotely transmit environmental temperature, humidity values and working status parameters to the upper computer, suitable for the requirements of unmanned substations. Users can program the upper and lower limits of temperature and humidity, cycle display mode, communication parameters, etc. through buttons.

The temperature and humidity controller has strong anti-interference ability, high reliability, and complies with GB/T15309-1994.
