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

? LCD Chinese character display, parameter settings, and alarms are clear at a glance, allowing for debugging without a manual.

? 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.

? Fire inspection function, effectively preventing fire pump corrosion.

? Comprehensive alarms, including inverter faults, remote meter disconnection and short-circuit faults, undervoltage timeout, and water level alarm indicators.

? Password-controlled timed shutdown, offering convenience in handling special issues.

? Programmable three-stage time-controlled start/stop (three starts and three stops), pressure variation by time period (six pressure values) (T option).

? Small flow shutdown function (i.e., sleep function), Model 147 features a nighttime small pump operation mode, providing convenience in energy-saving applications with special requirements.
