Product Description

                                               Intelligent  Controller for Air System (Double Fans)


The controller is designed on the basis of the latest national standard 16D303 atlas, and its control functions meet all the control requirements of fans and pumps which collected in the Atlas.  To maximize the integration of related secondary control devices, greatly optimize the secondary wiring work hours and secondary accessories.  And on the basis of the atlas, combined with the actual application situation involved in the real project, the controller's function is optimized.  The intelligent controller has characteristics as below:  
 

1) The reserved control port of forced start, which can realize the manual control in two or more places, as well as the starting device in any state.
