⚙️ Key Features & Dual Programmable Models
Model 1: ON-Time Scheduled Mode
Set custom ON-times up to 4 times per day. The pump switches ON automatically according to the scheduled time and switches OFF when the overhead tank gets completely filled to 100%.
Model 2: Complete ON & OFF Scheduled Mode
Set precise individual ON-times and OFF-times up to 4 ON times and 4 OFF times per day, allowing the pump to switch ON and OFF strictly according to set clock intervals.
Advanced Low AC Voltage Sensing
Avoids electrode polarization in water using long-life stainless steel plastic-molded conductive sensors requiring no frequent cleaning.
Dry-Run & Source Protection
Automatically shuts off the motor and signals a fault if running dry due to faulty foot valves, pipe air leaks, or low source conditions.
3-Phase Voltage Cut-Off Range
Automatically cuts power if supply voltage drops below 360V or crosses 500V AC across phases.
Comprehensive Visual & Controls
Includes 4-stage overhead tank level indicators, water flow status, voltage level display, Timer Mode status, LCD interface, and Hour/Minute program buttons.
