Using touch type as control programming, it can display the operating status of fans, water pumps, oil pumps, etc. and flame stepless change status at any time, with a full range of online help, simple operation, suitable for people of any cultural level.
B. Really unmanned operation and fully automatic operation
It has the functions of automatic flame ratio adjustment, automatic furnace purging and automatic detection of flame, wind pressure and oil return pressure. In addition, the steam boiler also has the functions of continuous automatic water supply, automatic surface discharge control, and automatic detection of low and high limits of water level.
C. Fully automatic system start and stop
It has the functions of automatic start-stop setting, time correction, timing start-stop, multiple priority start-stops, pre-setting of working days, rest days, and automatic judgment of rest days.
The steam boiler has a standby function when the steam pressure is higher and a self-start function when the pressure is low; it has the function of automatically shutting down the boiler when the water level is super high and pre-discharging water when restarting.
D. High reliability of the system
It has interlock protection functions for oil pump, water pump, fan overload, ignition failure, abnormal flameout, fan no wind, gas leak detection failure, gas leakage, low gas pressure, smoke temperature, gas pressure, and oil return pressure are too high; With operating password, system debugging password, and user program OEM protection password. In addition, the hot water boiler also has the interlock protection function of circulating water vaporization, circulating judged water, and the temperature of the outlet water exceeds the limit.
