This advanced computer control device has been achieved its controlling of 
pump’s RPM by inverter through the newest electronic technology, and 
equipped with presumptive terminal pressure control technology and various 
intelligent functions which can determine and control the pressure of water 
supply according to the amount of supplied water and usage.     
 
  Up to 6 pumps can be controlled with functions generally such as; stopping 

low flow using pressure tank, control, scheduled operation, warning 
abnormal state, full automated sequential operation, interval shift operation, 
skipping failed pump automatically, displaying operation data and data 
storing 

 

Remote controlling and monitoring functions by remote modem 
communication, and easy operating for anyone by displaying of all screen 
view in Korean./ English / Chinese.
