WaterSwitch ComboStarter OT System

Sinicon WaterSwitch ComboStarter OT System I; consists a ComboStarter (WC9526OT) and a WaterSwitch; is a Digital Electronic Starter with built in WaterSwitch based automatic Water Level Controller and programmable ON/OFF timer. It prevents overhead tank from overflowing and also prevents the overflowing of sump, well etc. Thanks to Sinicon WaterSwitch, the user need not worry about switching the electric water pump ON and OFF and makes water available round the clock.The easily programmable timer helps to programme the water pumping duration based on the water availability in a bore well for domestic and/or agricultural applications. The ComboStarter also prevents pump from running when sump/well is empty, or during low or high voltage or dry run situation, thus avoiding damage to motor resulting in cost saving in electricity and maintenance.
