In the current epidemic prevention phase, it is very important to keep warm and improve immunity. When a household uses a heating system, proper ventilation should be carried out. In everyday ventilated environments, there is usually no COVID-19 in the air. It is recommended to open the Windows at least twice a day.
At present, many residential areas in the implementation of the "can not go out" policy, after-sales technical personnel can not enter the user's home for inspection. When the heater fails, don't worry. You can consult the after-sales technical personnel online to solve it. You can also conduct self-inspection according to the following contents.
1. If the water pressure of the wall-hung furnace is too low for alarm/shutdown, the water pressure of the wall-hung furnace should be checked in case of sudden alarm or shutdown of the furnace. The normal pressure of the wall-hung furnace in the heating process is 1.5 ~ 2.0bar. If the water pressure of the wall-hung furnace is too low and the boiler cannot be started normally, the boiler will automatically alarm and the LCD panel will display the corresponding fault code.
The user rotates the water supply button at the bottom of the boiler to observe the water pressure gauge on the operation panel. When the pressure of the liquid crystal panel reaches the normal range, the user turns off the knob immediately and restarts it to operate normally. (Close the gas valve when replenishing water, and open the gas valve after replenishing water)
2, the wall furnace ignition failure and other faults
Ignition is related to natural gas, ignition pin and gas. When the gas wall-hung furnace is not on fire, first determine whether the natural gas is sufficient, whether the valve is opened, and then check the ignition position of the ignition needle or the electrode of the ignition needle is deviated, resulting in the ignition point is not on fire.
Domestic hot water is sometimes hot and sometimes cold
Normal heater heating, hot water when the cold temperature when the heat is not stable, may be due to these reasons: check the water pressure change big or air pressure change of valve or circuit board if there is a problem of tap water flow less, check the water temperature of high temperature sensor of air pressure switch contact undesirable thermal flow sensor is bad, the minimum power.
When using domestic hot water, adjust the mixing faucet, the cold water flow is too large, the hot water flow through the gas wall-hung stove is too small, the stove automatically adjusts, the situation is serious, the wall-hung stove may be flameout, the hot water suddenly becomes cold, the flame suddenly becomes small. Therefore, in the use of hot water, it is best to adjust the temperature control button on the gas wall hanging furnace, so that it reaches the appropriate temperature, the mixing faucet does not do more mixed water, in order to ensure that the furnace is in a stable working state; Hot water hot water plate excessive change of water, will also lead to hot water cold, should timely contact the special after-sales cleaning descaling; Small area of water pressure instability may cause instantaneous or large flow, hot water will be cold.
The fault code on the display screen can also help users quickly find the cause of the fault, easy to repair. Special period, there is a temporary failure do not panic, you can first self-test, observe the fault code, and professional online communication and teaching processing, to help restore warmth as soon as possible.
