 Additional notes: 



 The product is the company developed a with Chinese LCD intelligent temperature and humidity controller is widely used in the communications room, the real 

 Laboratory, workshop and warehouse, the majority of products sold in Eastern and Southern China, by the customer screen. This product is free comes with a host computer temperature and humidity control 

 The receiving program to facilitate not to the secondary development of customers. This product also has a secondary development agreement for engineering supplier for secondary development, set 

 Into other control systems, temperature and humidity control system functions. 



 The product to bring the company's network modules (network of temperature and humidity controller), which can transmit information over the WAN, receiving the control host 

 Without a fixed IP address on the public network can be, you can achieve remote monitoring of temperature and humidity controlled point data network of temperature and humidity control system. 
 The AT820 intelligent probe of the temperature and humidity controller is divided into external, built-in and 485 transmission, user-friendly
