from accurately detecting the water level. With power to the system on, and water above the probe level, set the thermostat so there is no call for heat and allow the burner to shut down. Then, slowly lower the water in the boiler to a point below the probe. The amber LED lamp should turn on and the relay will open after a 15 second delay.

This is converted to DC using Bridge rectifier. Ripples can be removed by the capacitive filter, and by using voltage regulator 7805 you can regulate voltage to +5v. It is required for the operation of different ICs and components.
