Controls both your WASA supply motor and booster pump automatically — lifts water from the city line into your underground tank, then up to the rooftop, with multi-layer safety at every step.
Two motors, two tanks, three operating modes, a multi-page rotating LCD, and a Fill Guard that learns your tank's fill time and warns you if a sensor fails — without ever leaving your house without water.
৳7,500
The WASA motor lifts water from the city supply line into your underground tank whenever the line has water. The Regular motor lifts water from the underground tank up to the rooftop overhead tank whenever the level drops to the set point. Both motors are protected from dry-running and bad voltage at every step.
The Fill Guard times how long each 25% fill step takes and learns it over repeated cycles using a weighted rolling average. If a motor runs 25% longer than its learned fill time without the tank reaching full, the controller flags a likely failed top-tank sensor — while keeping the motor running on its other safety rules rather than stopping your house's water supply. It warns you without cutting you off.
Stops the motor if the underground tank runs empty. Protects both WASA and Regular motors.
Adjustable low and high thresholds with per-motor voltage-drop compensation to correct for supply sag while a motor is running.
Learns how long each fill step takes. Flags a likely failed sensor if a motor runs 25% past the learned time — without stopping your water supply.
Total run time and start counts per motor, total powered-on time, live sensor test, and learned fill/drain timings per tank stage.
On sensor mismatch the display shows a persistent error but water delivery continues based on the highest confirmed-wet sensor — it does not halt the system.
AUTO runs both motors fully automatically based on tank levels. SEMI lets you start a motor manually and it stops automatically when the tank is full. MANUAL gives you full control — you start and stop the motors yourself — but the safety protections (dry-run, voltage, max run-time) remain active in all three modes.
Fill Guard times how long the motor runs to fill each 25% step of the overhead tank and learns a weighted average over repeated cycles. If a run exceeds the learned time by 25% without the tank reaching its OFF level, it flags a likely failed sensor on the display. Critically, it does not stop your water — the motor keeps running on its other safety rules. It warns you so you can check the sensor, without cutting off your household supply.
Yes. The setup menu lets you configure PULLUP WET-LOW or PLAIN WET-HIGH sensor wiring, and a live sensor-test screen shows the raw state of every sensor so you can verify the wiring is correct.
Protect both your WASA line motor and booster pump with automatic control, Fill Guard sensor monitoring, and full voltage protection.

Manual motor start/stop by button press count, independent of current mode. UP/DOWN works in all three modes.
All settings are stored in persistent memory and survive power loss. The controller includes a watchdog that auto-resets if the program hangs, and a factory-reset combination (hold UP+DOWN at power-on) that preserves usage reports and learned fill times — resetting only settings.
