Auto-cut-off protection: numerical control automatic ignition, auto-cut-off protection will shut off gas supply immediately once flame out accidentally and no gas leakage
Water-controlled automatic ignition: water-controlled automatic ignition is applied for unit, double-ignition device with high rate, flame is sensed by ion, this sensitive control can be achieved, and easy and convenient to operate
Anti-dry combustion protection: once dry combustion occurs, protection device will shut-off gas supply automatically
Over-pressure protection: once water pressure is over than 1.0mPa, unit heater will relieve pressure automatically to avoid damage
Low water pressure start-up function: when water pressure is less than 0.025mPa, water heater can also start-up, is suitable to user who living in high floor or lower water pressure
Anti-freezing protection: when temperature is very low, remove water discharge valve to discharge cumulative water inside pipe to avoid damage caused by freezing
Energy saving: advanced combustion system with Winter/summer switch, water temperature can be adjusted in maximum range, save about 20% of energy
