In the energysaving control field, the conventional method used is that of constant pressure control of the water supply with inverters. However, as EconoPilot employs a method of variable water pressure control corresponding to flow volume, the system can raise the energysaving ratio up to 90 percent. This paper describes the principles of the system and its basic functions, along with a case study of some practical applications. INTRODUCTION With the background of fulfilling public mitments for the prevention of global warning, many countries have consolidated related laws and regulations aiming to reduce ene
