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.

Low Water Cut-Offs 500/600/700 Series - Hydrolevel
The control should be located below the level of the primary low water cut-off but above the lowest permissable water line as specified by the boiler manufacturer. Note: For installations in equalizing lines, Hydrolevel recommends the use of Safgard Tees (see step 2). Low Water Cut-Offs 500/600/700 Series 24 VAC Operating Voltage

Water Level Indicator Project Block diagram by Edgefxkits.com. A step-down transformer 230/12v is used in the power supply. It is used to step down the voltage to 12v AC. 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.
