TW3000A Intelligent Water Supply Controller

After years of field use and user feedback, the TW controller has evolved to include the following practical features:

 Online parameter adjustment is convenient, especially the ability to set pressure using only the plus and minus keys, providing great convenience for both manufacturers and users.

 The set pressure and actual pressure are displayed with three-digit accuracy, thereby improving the display and control precision for 1.6Mpa and 2.5Mpa remote pressure gauges. This offers convenience in high-rise water supply and special applications.

 A complete range of models is available, including six soft-start models with Chinese character LCD display, making it easy to select the right model for specific applications.

 Comprehensive alarm functions include inverter faults, remote gauge disconnection and short-circuit faults, undervoltage timeout, and water level alarm indicators.

 Password-controlled timed shutdown provides convenience for handling specific issues.

 Programmable three-stage time-controlled start/stop (three starts and three stops) and time-based pressure adjustment (six pressure levels) (T option).

 Features small flow shutdown (i.e., sleep function). Model 147 includes a nighttime small pump upper and lower limit operation mode, offering convenience for applications with specific energy-saving requirements.
