Application

Household Deep Well Pump Control
This Smart Water Pump Starter provides automatic logic for rooftop water tank systems:

Rooftop water shortage + well water shortage → Pump does not start

Rooftop water shortage + well sufficient water → Pump starts

Rooftop tank full → Pump stops to prevent overflow

 

Booster Pump Water Supply
Works seamlessly with pressure switches or electric contact gauges.

Pressure drops to cut-in → Pump starts

Pressure rises to cut-out → Pump stops

Protection

Dry Run Protection:
Install probes in the well or operate sensor-free to prevent motor damage. When water shortage occurs, the pump automatically stops.

 

Signal Delay & Anti-Rust Protection:
Adjustable 0–120s start-stop delay prevents frequent motor cycling.

An optional anti-rust cycle periodically runs the pump for 10 seconds (adjustable) to avoid impeller rust and blockage.

 

This controller is ideal for homes, small buildings, and villas where stable water pressure and system protection are essential. It enhances convenience and extends pump lifespan, minimizing maintenance effort.
