1.Function Summary: The system uses alcohol-baed fuel as energy, and integrates heating function and integrated installation. 2.Heating function: 1) Water temperature:temperature range 20-85ºC, boiler start and boiler stop are adjustable. 2)Water pump control: Start the circulating pump temperature 35ºC 3)Timing function: total 8 stages timing functions 4) Over temperature protection: When the water temperature exceeds 85ºC 5)Return water temperature protection: when the difference between the return water temperature and the outlet water temperature is higher than the set degree, the protection will downtime. 6)Freeze-proofing function: when the controller is powered on, it starts by default. When the return water temperature is lower than the set temperature, the freeze proffing function is automatically turned on. 7)Leakage protection function: when the detect the leakage current is more than 25mA, cut off the power. 8)Temperature sensor damage protection: when the temperature sensing signal exceeds the normal (short circuit or open circuit). protection downtime. 9)Flame out portection function: Protective downtime in case of accidental flame out. 10)Fuel level detection function: Real time detection of fuel level remaining according to ultrasonic probe 11)The product can be equipped with Wifi, NB-Lot function
