Our Programmable LED model provides all the features provided by our Indicator models together with digital voltage display & user programmable settings for dry run delay, start level for the motors etc..

Functions:

1) Switches on the motor when the water level in the over head tank reaches minimum level.

2) Switches off the motor when the water level in the over head tank reaches maximum level.

3) Functions 1-2 are co-ordinated with the levels of water in the sump, ie. the motor is not started when the water level in the sump as at minimum, it is started as the water level approaches maximum in the sump.

4) We also have a special dry run cut off Program which will be very useful for the bore well/wells with less yield connected to submersible pumps. This unit will have a dry run cut off time delay in the initial as 3 min or 5 min depending upon the time taken for the water to reach the OH tank, but once the water starts flowing in case the water flow stops before filling the tank or sump it will cut off pump with in 30sec or 45sec from the moment of flow stoppage. Again it will restart on its own according to the programmed 1hr, 2hr or 3hr & try to top up the tank. It will automatically keep trying until the OH tank or collection source is 100% full. This will help you to collect maximum water from the yield available without any manual intervention. It will also help you to protect your pumps from burnouts due to dry running. The pump on time can also be restricted for only 10mins, 20mins, 30mins for every operation irrespective of the collection tank is full it will stop the restart after certain time delay.

Indications:

1) Overhead tank multiple level indications.
2) Sump multiple level indications.
3) Exact water flowing indication from sump to ov erhead tank.

Additional:

1) Model is equipped with High and Low Voltage Cut-off with exact digital
voltage display.
2) Manual and Auto mode of operation Switch is provided.

Suitability:

1) This model is well suited for all domestic applications in the Sump-Overhead tank modes where the water supply is lesser and/or the users are more.
2) Can also be used for Bore well/Open well-Overhead tank modes of operation.
3) Can be used for rainwater pumping operations.
