 ◆ MCU using automatic control, easy operation, with temperature control function. Demand for imported water heater can achieve double the temperature range control 60 ℃ - 70 ℃, 65 ℃ - 78 ℃. 
 ◆ imported water temperature and overheat sensor thermistor, stable and reliable control of sensitivity, accuracy ± 0.5 ℃. 
 ◆ Power full testing, user-friendly design, LED flash code indicates the heater working conditions. 
 ◆ fire way to determine: patented, shock-free signal acquisition, high sensitivity, good consistency, can be a reliable indication of fire and control the shutdown. 

 ◆ heater with overvoltage, undervoltage protection, motor, solenoid valve, glow plug short circuit protection, ignition sensor circuit protection to ensure safe and reliable heater. 
 ◆ automatic blood pressure heater main motor start, the ignition time is shorter, lower power consumption. 
 ◆ Working voltage range, glow plugs and the main motor has been running regulator; suitable for use altitude of 5000 meters. 
 ◆ efficient combustion chamber and heat exchanger structure to ensure heater combustion efficiency above 80%. 
 Special Note: The selection of the appropriate grade of light diesel oil. Heater using the same grade of fuel with the engine, if equipped with a separate tank, the fuel is used at ambient temperature can not be frozen or paraffin, suction pump for the heater to ensure smooth
