What's wrong with Weineng floor heating f.20

F.20 Meaning: the overheat protection function is started.

Cause: The probe of the water supply sensor is wrongly connected or faulty, and the gas heating water heater is not turned off.

If the Weineng gas-fired water heater fails, a failure code will be displayed on the display screen, which will replace all other displays. If multiple faults occur at the same time, the relevant fault codes will be displayed alternately for about 2 seconds.

Use of Weineng wall-hung boiler

1. Regarding the water pressure, users should check whether the indication of the water pressure gauge of the wall-hung boiler is within the specified range before using it. The standard water pressure specified in the manual is 1- 1.2 Pa. However, in the actual use process, because there is some air in the heating system and boiler, when the boiler is running, the air in the system is continuously discharged from the exhaust valve in the boiler, and the pressure of the boiler will drop irregularly.

When heating in winter, the water in the heating system expands when heated, and the water pressure in the system will rise, and then the pressure will drop after the water is cooled. This is a normal phenomenon.

2. When it freezes in winter, the wall-hung boiler can be electrified for a long time. Especially in winter, if the wall-hung boiler or heater has been filled with water, it is necessary to set up antifreeze, prepare enough electricity and gas for the wall-hung boiler, and avoid the radiator and the boiler water pump, heat exchanger and other parts from being frozen. Various brands of heating wall-hung boilers have anti-freezing function. Please refer to the instruction manual for specific operation methods.

3. With regard to energy saving, it is not advisable to turn the hot water faucet to the maximum at once: "When the water output exceeds 3 liters per minute, the wall-hung boiler can work normally." When the hot water faucet is turned on until the hot water flows out, the wall-hung boiler has a delay process of about 6 seconds. At this time, the pipe between the wall-hung boiler and the faucet is cold water, so it is cold water even if the faucet is opened to the maximum. If you turn it to the maximum, you will waste a lot of cold water.

4, solar terms, turn off or turn down the radiator valve of the unoccupied room: If the housing area is large, there are many rooms and the population is small, then the radiator valve of the unoccupied or low-frequency room can be completely turned off or turned down, which is equivalent to reducing the heating area, saving energy, speeding up the heating of the normal use space and reducing the gas consumption.
