Sell central heating gas boiler

Description

Ailunsi gas boilers with *0 protection function, Anti-freezing, when the circulating water temperature is lower than 5 Centigrade, the water pump runs automatically, and the combustion work to heat the water at minimum power status.When the water temperature is up to *0 Centigrade, the system stops working automatically. Water pump anti-seizing, Every *4 hours of standby, the water pump runs automatically for one minute, effectively preventing waterway blocking, prevent water pump from being seized. Bypassing protection, When the main heating circulation is closed or bloced accidentally, the by-pass valve is opened automatically to protect the system . Sanitary hot water first, When the water flow is too small, the sanitary hot water is firstly provided, and the diagnostic status show the code indicating the circulating water is insufficient, Guarding against over high temperature, When the water temperature is up to the utmost margin temperature *0 Centigrade, the gas proportioning vaalve is closed and the system stops working. Wind pressure switch protector, When the fan motor is out of order, when the flue is blocked, or the backwards air pressure is too high or if there is backwards wind, the wind pressure switch automatically close the boilers. Safety valve prevent the heating water system from over high pressure. When the pressure in heating water system is up to 3bar, the gas safety valve protector opens automatically to decrease pressure. Flameout protectors and re-ignition protectors, When the combustion is stopped accidentially, the gas proportioning valve is closed automatically in *0 seconds. Automatic protectors monitoring failured thermal sensor and multi-functional diagnostic, When the thermal sensor on the heating pipe and sanitary hot water pipe was encountered short circuit, or broken, or the resistance is abnormal, the failure can be diagnosed and diagnostic code displayed on the controller display pannel.
