1.       Auto-cut-off protection: numerical control automatic ignition, the auto-cut-off protection will shut off gas supply immediately once flameout accidentally, and no gas leakage.

2.       Water-controlled automatic ignition: the water-controlled automatic ignition is applied for the unit, double-ignition device with high rate, the flame is sensed by ion, this sensitive control can be achieved, and easy and convenient to operate.

3.       Anti-dry combustion protection: once dry combustion occurs, the protection device will shut off gas supply automatically.

4.       Over-pressure protection: once water pressure is over than 1.0Mpa, the unit heater will relieve the pressure automatically to avoid damage.

5.       Low water pressure startup function: when water pressure is less than 0.025Mpa, the water heater can also startup, it is suitable to the user who living in high floor or lower water pressure.

6.       Anti-freezing protection: when temperature is very low, remove the water discharge valve to discharge cumulative water inside pipe to avoid the damage caused by freezing.

7.       Energy saving: advanced combustion system with the Winter/summer switch, the water temperature can be adjusted in the maximum range, save about 20% of energy
