Guide: Gas-fired steam boilers are the main power to provide hot water for industrial production and daily life. Choosing a gas-fired steam boiler with long service life, high heat transfer efficiency, and high cost performance is of great significance to the enterprise. In order to maintain a long service life, protective measures from the manufacture, installation, and operation of the boiler to the later period are very important.

Gas-fired steam boilers are the main power to provide hot water for industrial production and daily life. Choosing a gas-fired steam boiler with long service life, high heat transfer efficiency, and high cost performance is of great significance to the enterprise. In order to maintain a long service life, protective measures from the manufacture, installation, and operation of the boiler to the later period are very important.

　　1. High temperature protection

　　When the dry burning protector detects that the temperature in the furnace is higher than 95, it cuts off the power of the heating tube to prevent the temperature from further increasing.

　　2, record and save function

　　The various parameter settings of the boiler are equipped with automatic recording and saving functions, even if the power is cut off, there is no need to reset. When the time setting of the gas-fired steam boiler is completed, it can run as usual after power off, and it cannot be corrected after power on.

　　3, antifreeze function

　　When the controller is energized, when the temperature is detected to be lower than 3 degrees, the heater starts to heat; when the temperature is detected to rise to 8 degrees, the heater stops heating.

　　4, leakage protection

　　When the system detects that the leakage current is greater than 15 mA, it will immediately cut off the power supply to prevent electric shock after contact. At the same time, the display will prompt fault codes and warnings. After troubleshooting, the controller can resume normal operation.

　　5, constant temperature control function

　　If the working temperature is not set after power on, the system will work at 50 degrees according to the set default parameters; if the working temperature is set, the system will work at the set temperature.

　　After 　　is turned on, the controller detects that the heating temperature is 8 degrees lower than the set temperature. Turn on the heating tube according to the set gear. When it is detected that the heating temperature is equal to the set temperature, the power supply is cut off to stop heating. When the temperature slowly drops below the set temperature of 8 degrees, the heating tube is turned on again to make the circulation achieve the purpose of constant temperature control.
