How It Works

Your pump, on autopilot

Four steps. Once set up, you never think about your water pump again.

01
◈

Sensor Probes Detect Water Level

Conductive probes installed at HIGH and LOW positions inside your overhead tank continuously monitor water level. No floats, no mechanical parts that can fail.

TECH NOTE // The probes send a 5V signal through the water column. Water touches BOTH → FULL. Only LOW submerged → time to pump.

Now your water pump knows to stop running when the overhead tank is full and runs again when the water level in your tank goes low

Yes. The controller is compatible with most standard household water pumps

If you have a 0.5 Kwh pump and if it over runs for about 10 mins, then approximately you are wasting 1000 liters of water. By installing this controller, you will be saving 1000x30x12=360000 liters of water per year. (Note that this is an approximate calculation)

If you have a 0.5 Kwh pump, and it over runs for 10mins, it will waste approximately Rs 1.00, which is Rs 360.00 per year. (Note that this is an approximate calculation)

Wire requirement is very much subjective to each of household, and there is no standard length that we will be able to supply. So we decided not to include it.

The controller has a 3-second memory hold on the relay state. When power is restored, it re-reads the sensor and resumes the correct state. It will not start the pump if the tank is already full, even after a prolonged outage.

Yes — there is an optional second sensor input for your sump. If connected, the controller will not start the pump if the sump is empty, protecting your motor from dry-run damage. Key for city homes with municipal supply.
